When people say that a dog is “stoned” or “high,” they are usually talking about cannabis intoxication. This happens when a dog is exposed to enough tetrahydrocannabinol, or THC, to cause noticeable effects. THC is the main chemical in cannabis that causes intoxicating effects. Dogs can become exposed when they eat marijuana flower, cannabis edibles, oils, concentrates, gummies, or other products that contain THC.
Cannabis toxicity in dogs is a medical condition that should be taken seriously. A dog that has consumed THC may become very sleepy, weak, confused, or unsteady. Some dogs have trouble walking and may stumble as if they cannot control their legs. Others may tremble, vomit, urinate without control, become sensitive to sounds or movement, or behave differently than normal. Severe cases can affect body temperature, heart rate, blood pressure, and breathing.
Dogs appear to respond to THC differently from humans. One reason involves the cannabinoid receptors found throughout the body. According to the Merck Veterinary Manual, dogs have a high concentration of CB1 cannabinoid receptors in areas of the brain that help control movement and important body functions. This may help explain why THC exposure can cause major problems with coordination and other nervous system functions in dogs.
A dog does not have to intentionally eat cannabis flower to become intoxicated. In many cases, exposure happens when a dog finds a cannabis product in a place that seems interesting or smells like food. Dogs may pull marijuana from a bag, eat discarded cannabis material, get into a trash can, or take an edible from a table or counter.
Edibles can be especially concerning because they may contain much more than THC. A dog that eats a cannabis brownie, cookie, candy, or other food may also consume ingredients that create separate health risks. For this reason, knowing exactly what the dog ate is important. Saving the package, label, or ingredient list can help a veterinarian evaluate the situation.
The strength of the cannabis product also matters. Cannabis products can contain very different amounts of THC. Concentrated oils and other extracts may contain much higher levels than some forms of plant material. The amount swallowed, the dog’s size, and the concentration of THC can all affect the severity of the reaction. Merck reports that dogs may develop mild clinical effects at THC doses as low as about 0.3 to 0.5 milligrams per kilogram of body weight, although individual responses can vary.
Symptoms do not always appear immediately. After a dog swallows THC, signs commonly begin within about one to two hours, although onset can sometimes take longer. The dog may first seem unusually tired or quiet. As the effects increase, the owner may notice poor balance, slow movements, strange behavior, vomiting, trembling, or difficulty walking normally.
The effects may also last longer than many owners expect. THC is stored and distributed through body tissues, and dogs do not eliminate it immediately. In more affected dogs, signs can remain for one to three days. Most dogs have a good prognosis with proper supportive care, but recovery time depends on how much THC was consumed, the type of product involved, the dog’s health, and whether other toxic ingredients were swallowed.
There is no simple home remedy that instantly makes a dog sober. The main goal is to keep the dog safe while the body processes the THC. Treatment may involve observation, fluids, control of nausea, temperature management, and other supportive measures based on the dog’s symptoms. Mild cases may sometimes be monitored at home after professional assessment, while more serious cases may require treatment at a veterinary clinic or hospital.
Owners should not try unproven methods to make the dog recover faster. In particular, trying to make an already sleepy or poorly coordinated dog vomit can be dangerous. A dog that cannot swallow normally may inhale vomit into its lungs. Veterinary guidance states that inducing vomiting is generally unsafe when an animal is neurologically unstable or has a high risk of aspiration.
Instead, the safest first step after known or suspected cannabis exposure is to contact a veterinarian or animal poison service. Owners should provide as much information as possible, including the dog’s weight, the product involved, the estimated amount eaten, when the exposure occurred, and any symptoms that have appeared. Being clear about cannabis exposure can help the veterinary team choose the right care quickly.
Although marijuana poisoning can look frightening, most dogs recover when they receive appropriate care. Merck Veterinary Manual states that the prognosis is generally good and that clinical signs usually resolve within one to three days. Death from THC exposure alone is considered extremely rare, although serious complications can occur.
The key is to recognize the problem early and respond safely. A dog that becomes unusually sleepy, unsteady, weak, trembly, or confused after possible cannabis exposure should not simply be left alone to “sleep it off.” Owners should identify what the dog may have consumed, prevent further access to the product, contact a veterinary professional, and closely watch for worsening symptoms. Understanding what cannabis toxicity looks like is the first step toward helping an affected dog recover safely.
How Can You Tell If a Dog Is High?
Dogs exposed to marijuana can show a clear set of physical and behavioral changes. These signs are usually caused by tetrahydrocannabinol, or THC, which is the main chemical in cannabis that produces an intoxicating effect. Dogs can be especially sensitive to THC because of differences in their nervous system and the way cannabinoid receptors are distributed in their brain.
A dog that has eaten marijuana may seem sleepy, weak, confused, or unable to walk normally. However, not every dog reacts in exactly the same way. The signs can depend on how much THC the dog consumed, the strength of the product, the dog’s body size, and whether other ingredients were eaten at the same time.
Knowing the common signs of marijuana toxicity can help owners recognize a possible exposure early and seek veterinary advice before the dog’s condition becomes more serious.
Common Signs of Marijuana Toxicity in Dogs
One of the most common signs of THC poisoning in dogs is unusual sleepiness or lethargy. A dog may lie down for long periods, seem difficult to wake, or show little interest in normal activities. Some dogs appear unusually relaxed, while others may seem confused or unaware of what is happening around them. Merck Veterinary Manual lists lethargy among the most frequently reported signs of THC exposure in dogs.
Another major sign is poor coordination, also called ataxia. A dog with ataxia may stumble, sway from side to side, cross its legs while walking, or have trouble staying upright. The dog may look as though it is drunk. Some dogs can stand but have trouble walking in a straight line. Others may become too weak or unsteady to walk safely.
Changes in the eyes may also occur. The pupils can become larger than normal, which is known as pupil dilation. The dog’s eyes may appear glassy or unusual. Some dogs may also have abnormal eye movements or difficulty focusing.
Dogs affected by THC can become more sensitive to touch, sound, or movement. A small noise may cause a stronger reaction than expected. A dog may suddenly twitch when touched or become startled by normal movement nearby. This increased sensitivity is sometimes called hyperesthesia.
Trembling, twitching, or head bobbing may also develop. Mild trembling does not always mean the dog is having a seizure. However, severe or repeated shaking should be taken seriously, especially if the dog is unable to respond normally.
Vomiting and drooling are other possible symptoms. In reported THC exposures, vomiting is one of the more common digestive signs. A dog may also lose interest in food or appear nauseated.
One particularly noticeable symptom is loss of bladder control. A dog that is normally house-trained may suddenly urinate while lying down, sleeping, or walking. Urinary incontinence is a recognized sign of marijuana toxicity in dogs and can be an important clue when it appears together with sleepiness and poor coordination.
Behavior can also change. While many affected dogs become quiet and sleepy, some may become restless, agitated, or unusually vocal. They may whine, bark, pace, or react strongly to their surroundings. The ASPCA also lists sleepiness or, in some cases, unusual excitement among the possible signs of marijuana poisoning.
Heart rate and body temperature can change as well. Some dogs develop a slower-than-normal heart rate. Body temperature may fall, although increases in temperature can also occur in some cases. More serious cases can involve low blood pressure or respiratory depression. These problems require prompt veterinary attention.
When Symptoms Usually Begin
The timing of symptoms depends partly on how the dog was exposed to THC. In most household cases, dogs become intoxicated after eating marijuana, cannabis edibles, or products containing concentrated THC.
After THC is swallowed, clinical signs often appear within about one to two hours. In some dogs, especially under certain feeding conditions, signs may take several hours to become noticeable.
Older veterinary guidance has also reported that signs can begin within about 30 to 90 minutes after marijuana ingestion. This means owners should not assume that a dog is safe simply because it looks normal immediately after eating a cannabis product.
The effects of edibles can be harder to predict. Cannabis gummies, brownies, cookies, chocolates, oils, and other products may contain concentrated amounts of THC. They may also contain ingredients that cause separate health problems. For example, chocolate, xylitol, raisins, caffeine, or very high levels of fat can create additional risks that are separate from the effects of THC.
For this reason, the exact product matters. If a dog eats an edible, owners should keep the package or ingredient label if possible. A veterinarian may need to know the THC concentration, serving size, number of missing pieces, and other ingredients.
How Long Can the Symptoms Last?
Marijuana intoxication in dogs can last much longer than many owners expect. THC is stored and distributed in body tissues, and dogs may continue showing effects even after the initial exposure has passed.
According to the Merck Veterinary Manual, clinical signs in significantly affected dogs can continue for one to three days. Some dogs may begin improving much sooner, especially after a mild exposure, but recovery time can vary.
Improvement usually happens gradually. A dog may first become more alert, then begin standing and walking more steadily. Coordination, appetite, normal behavior, and bladder control may return over time.
Owners should continue watching the dog even when the symptoms appear to be improving. A dog that is still sleepy or unsteady can fall from furniture, slip on stairs, or injure itself while walking.
Severe symptoms should not simply be watched at home. A dog that becomes unconscious, has trouble breathing, develops seizures, repeatedly vomits, collapses, or cannot stand should receive immediate veterinary care. Although death from THC exposure alone is considered extremely rare, serious complications can occur.
A dog that is high from marijuana often shows a combination of sleepiness, poor coordination, unusual eye changes, trembling, vomiting, increased sensitivity, or loss of bladder control. Some dogs become very quiet, while others may appear restless or agitated. Symptoms often begin within a few hours after the dog eats a THC-containing product and can continue for one to three days in more affected cases.
Because these symptoms can also occur with other types of poisoning or illness, owners should not rely on appearance alone to make a diagnosis. If marijuana exposure is known or suspected, contacting a veterinarian is the safest way to determine what level of care the dog needs. Keeping the cannabis package or ingredient list can also help the veterinarian understand the possible dose and identify any other toxic ingredients the dog may have consumed.
What Should You Do Immediately If Your Dog Ate Marijuana?
If you think your dog ate marijuana or a product that contains THC, act quickly but stay calm. Cannabis can cause poisoning in dogs, especially when they eat concentrated products or large amounts. Dogs may become sleepy, weak, unsteady, or unusually sensitive to sounds and touch. More serious cases can involve low body temperature, low blood pressure, seizures, or severe sedation.
There is no safe way to instantly make a dog “unstoned” at home. The first steps are to prevent your dog from eating more, collect useful information about the exposure, and contact a veterinarian. Early guidance can help determine whether your dog needs treatment right away or can be watched safely at home.
Remove Access to the Cannabis Product
The first thing to do is move the marijuana product away from your dog. Check the floor, table, trash can, bag, or other area where the exposure happened. Remove any remaining cannabis so your dog cannot eat more. If there are other pets in the home, keep them away from the area as well.
Do not throw away the package yet. Packaging can provide important information about the product. A veterinarian may need to know whether your dog ate dried cannabis, an edible, THC oil, a concentrate, a gummy, or another product. The strength of THC can vary greatly between products, so this information can help the veterinarian estimate the possible risk.
If your dog ate an edible, check the complete ingredient list. The cannabis itself may not be the only concern. Some edibles can contain ingredients that are also harmful to dogs. Chocolate, raisins, caffeine, and certain sweeteners may create separate health risks. This is one reason it is important to tell the veterinarian exactly what product your dog ate rather than simply saying that the dog ate marijuana.
Do not allow your dog to continue licking spilled oil, crumbs, wrappers, or containers. Even small amounts left on packaging may contain THC.
Determine What the Dog May Have Eaten
Before calling the veterinarian, gather as much information as you can. You do not need to know every detail, but accurate information can help the veterinary team decide what should happen next.
Try to identify the type of cannabis product involved. Find out how much may be missing and when your dog might have eaten it. If the label lists the amount of THC in each serving or package, keep that information available. You should also know your dog’s approximate weight.
For example, eating a small amount of dried marijuana may create a different level of concern than eating several concentrated THC gummies. The amount of THC in modern cannabis products can vary widely, and stronger products can cause more serious effects.
If you are unsure how much your dog ate, tell the veterinarian that the amount is unknown. Do not guess if you have no reasonable estimate. It is better to provide clear information about what you know and what you do not know.
Pay attention to your dog’s current condition as well. Tell the veterinarian if the dog is walking normally, sleeping heavily, stumbling, vomiting, trembling, urinating unexpectedly, or acting unusually. Symptoms can help determine how much veterinary attention is needed.
Contact a Veterinarian
Contact your veterinarian as soon as you know or strongly suspect that your dog has eaten marijuana. If your regular clinic is closed, contact an emergency veterinary hospital or an animal poison service that serves your location.
The ASPCA recommends contacting a veterinarian or animal poison control service as soon as possible after suspected marijuana exposure. Veterinary guidance is important because the best response depends on when the exposure occurred and whether the dog is already showing symptoms.
Be direct about what your dog ate. Tell the veterinary team that marijuana or THC may be involved. Give them the product name, THC strength if known, approximate amount eaten, time of exposure, your dog’s weight, and any symptoms you have noticed.
Accurate information helps the veterinarian choose safer treatment. Marijuana intoxication can cause signs that resemble other medical problems, including poor coordination, weakness, vomiting, and severe sleepiness. Knowing that cannabis exposure occurred can make it easier for the veterinary team to understand what may be happening.
Do not delay getting help because you feel uncomfortable discussing cannabis. The veterinarian’s main concern is treating the animal safely.
Do Not Try to Make the Dog Vomit Without Veterinary Advice
Some owners may think that making a dog vomit is the quickest way to remove marijuana from the stomach. However, this can be dangerous in a dog that is already sleepy, weak, or poorly coordinated.
Veterinary guidance states that decontamination may sometimes be considered soon after THC ingestion, but only when the patient is still clinically normal. Dogs that already have neurological symptoms may have trouble protecting their airway. Vomit could then enter the lungs, causing aspiration and potentially serious complications.
Do not give hydrogen peroxide, salt, oil, milk, or other home remedies unless a veterinarian specifically instructs you to do so. The correct response depends on the product, timing, amount consumed, and your dog’s condition.
If the exposure happened very recently and your dog is still acting completely normal, a veterinarian may decide whether decontamination is appropriate. This decision should be made by a professional rather than attempted at home without guidance.
Keep Your Dog Safe While Waiting for Instructions
While contacting the veterinarian or preparing to travel to a clinic, place your dog in a quiet and safe location. A dog affected by THC may become unsteady and can fall from stairs, beds, or furniture.
Keep the dog at floor level and away from hazards. Limit noise and unnecessary handling because some dogs become unusually sensitive to sound and touch after THC exposure.
Watch your dog’s breathing, alertness, and ability to stand. If your dog collapses, has trouble breathing, experiences a seizure, becomes unresponsive, or develops other severe symptoms, treat the situation as an emergency and seek immediate veterinary care.
Do not force food or water into a dog that is extremely sleepy or having trouble swallowing. A heavily sedated dog may not be able to swallow normally, which can increase the risk of choking or aspiration.
If your dog eats marijuana, the safest response is to act quickly and gather accurate information. Remove any remaining cannabis, save the packaging, identify the product and approximate amount eaten, and contact a veterinarian. Be clear about the possible THC exposure and describe any symptoms your dog is showing.
Do not try to make an affected dog vomit or use home remedies unless a veterinarian specifically tells you to do so. Dogs that are already sleepy or uncoordinated may be at greater risk of inhaling vomit into their lungs. Until professional help is available, keep your dog in a calm, secure place and watch closely for changes in breathing, alertness, movement, or behavior. Early veterinary guidance is the safest way to determine what care your dog needs.
Can You Get a Dog Unstoned at Home?
When a dog eats marijuana or another product that contains THC, there is no simple home remedy that can instantly make the dog sober. The safest response depends on how much the dog consumed, what type of product was involved, the dog’s size, and the symptoms that are developing.
Some dogs with mild THC exposure may be able to recover at home after they have been assessed by a veterinarian. However, home care should not replace professional advice. Dogs can become very sleepy, lose their balance, develop a low body temperature, vomit, or show changes in heart rate and blood pressure. Severe cases can require treatment at a veterinary hospital.
The most useful thing an owner can do is contact a veterinarian as soon as possible, explain what happened, and follow the instructions provided. Knowing the type of cannabis product, the amount that may have been eaten, and the approximate time of exposure can help the veterinarian decide what level of care is needed.
Why There Is No Instant Home Cure for THC Intoxication
There is no specific household treatment that immediately removes the effects of THC from a dog’s body. In most cases, treatment is based on supportive care while the dog’s body processes and eliminates the drug. Veterinary references report that symptoms often resolve within one to three days, although the exact recovery period can vary.
This means that common ideas about quickly “sobering up” a dog should not be relied on. Giving food, taking the dog for a walk, putting the dog in a cold shower, or trying to make the dog more active will not remove THC from the bloodstream.
In fact, some attempts to make a dog more alert may create additional risks. A dog affected by THC may have poor balance and slow reactions. Forcing the dog to walk or exercise could cause a fall or other injury. A dog that is very sleepy may also have trouble swallowing normally, so forcing food, water, or other substances into its mouth may not be safe.
Supportive care is important because the body usually needs time to metabolize and eliminate the THC. General treatment for poisoning focuses on supporting normal breathing, circulation, hydration, body temperature, and neurological function until the toxic substance has been cleared.
The length and severity of intoxication can also depend on the product. A small amount of dried cannabis may create a different exposure than a concentrated oil, edible, or THC-rich product. Edibles can create additional concerns because they may contain chocolate, xylitol, raisins, caffeine, or other ingredients that are harmful to dogs.
Caring for a Mildly Affected Dog
A mildly affected dog may sometimes be monitored at home, but this should normally be done after speaking with a veterinarian. The Merck Veterinary Manual notes that mildly affected animals may be candidates for home monitoring once they are stable, able to walk, and able to maintain a normal body temperature.
Keep the dog in a quiet and comfortable area. THC can make some dogs unusually sensitive to noise, movement, touch, or other stimulation. A calm room with limited activity can make recovery safer and less stressful.
The recovery area should be at floor level. Keep the dog away from stairs, balconies, swimming pools, furniture, and other places where an unsteady animal could fall. Even a dog that normally climbs stairs without difficulty may stumble when affected by THC.
Supervise bathroom trips closely. A dog experiencing marijuana toxicity may walk slowly, sway from side to side, or have trouble standing. Some dogs also develop urinary incontinence, which means they may urinate without normal control. This is a recognized sign of THC poisoning and should not be mistaken for a behavior problem.
Continue watching the dog’s level of alertness. Mild sleepiness may occur, but the dog should still be monitored for worsening symptoms. Pay attention to whether the dog can stand, walk, respond to you, and breathe normally.
Food and water should also be handled carefully. Follow the veterinarian’s instructions about when the dog can eat and drink. A very sleepy dog may not swallow normally, which can increase the risk of food, water, or vomit entering the lungs.
Do not give medications, supplements, activated charcoal, or other substances unless a veterinarian specifically recommends them. Treatment decisions depend on the dog’s condition and the type and timing of exposure.
When Home Monitoring Is Not Appropriate
Home monitoring is not suitable for every dog. A dog with severe symptoms needs veterinary care rather than simple observation at home.
Seek urgent veterinary help if the dog becomes extremely weak, collapses, becomes difficult to wake, cannot stand, has trouble breathing, develops severe tremors, or has a seizure. Marijuana poisoning can also cause low body temperature, low blood pressure, abnormal heart rates, and, in rare severe cases, coma.
Repeated vomiting is another reason to contact a veterinarian. Vomiting can lead to dehydration, and a heavily sedated dog may be at greater risk of breathing vomit into the lungs.
The type of product the dog consumed also matters. A dog that ate a cannabis edible may have been exposed to more than THC. Chocolate, xylitol, raisins, caffeine, and other ingredients can cause separate forms of poisoning that may require specific treatment.
Very small dogs, puppies, older dogs, and animals with existing medical conditions may also need closer monitoring. A dose that causes mild symptoms in a large dog could have a stronger effect on a much smaller animal.
Owners should not wait for severe symptoms if they know their dog consumed a large amount of cannabis or a highly concentrated THC product. Contacting a veterinarian early gives the veterinary team more options for assessing and managing the exposure.
There is no instant home method for getting a dog unstoned. THC intoxication usually improves as the dog’s body processes the drug, and treatment mainly focuses on supportive care. Mild cases may sometimes be monitored at home after veterinary assessment, but the dog should be kept in a quiet, safe area and watched closely for changes in alertness, balance, breathing, vomiting, and other symptoms.
Do not force a sleepy dog to exercise, eat, or drink, and do not give medications or other treatments without professional guidance. If the dog cannot stand, is difficult to wake, has breathing problems, experiences severe tremors or seizures, or shows other worsening symptoms, seek veterinary care immediately. With appropriate monitoring and treatment, the prognosis for most dogs with THC toxicity is generally good.
Should You Make a Dog Vomit After Eating Marijuana?
Making a dog vomit may seem like a quick way to remove marijuana from the stomach. However, it is not always safe. Whether vomiting is useful depends on when the cannabis was eaten, how much was consumed, and whether the dog is already showing signs of THC poisoning.
In some cases, a veterinarian may decide that inducing vomiting can reduce the amount of THC that enters the body. This is most likely to be considered soon after the exposure and before the dog develops signs such as sleepiness, poor balance, trembling, or reduced awareness. The Merck Veterinary Manual notes that decontamination may be considered within about one hour of THC ingestion in dogs that are still clinically normal.
Once a dog begins acting intoxicated, trying to make it vomit at home can create more danger than benefit. For this reason, owners should contact a veterinarian or animal poison service before attempting any method designed to cause vomiting.
Why Vomiting Is Not Always Safe
Vomiting requires a dog to be awake enough to protect its airway. A healthy and alert dog can usually cough, swallow, and control its breathing while vomiting. A dog affected by THC may lose some of these normal protective responses.
Cannabis poisoning often causes lethargy and poor coordination. A dog may become very sleepy, weak, or unable to walk normally. Some dogs may also have unusual movements, trembling, or changes in their level of awareness.
If vomiting is triggered while a dog is heavily sedated or poorly coordinated, stomach contents may enter the airway instead of leaving through the mouth. This is called aspiration. Material that reaches the lungs can cause aspiration pneumonia, which may become a serious medical problem.
General veterinary toxicology guidance therefore advises against inducing vomiting when an animal is not neurologically stable, has lost a normal swallowing reflex, or has a high risk of aspiration.
This means owners should not assume that vomiting is appropriate simply because marijuana was swallowed. A dog that is already stumbling, extremely sleepy, weak, or difficult to wake should be evaluated by a veterinarian instead of being made to vomit at home.
When Veterinarians May Consider Decontamination
Veterinarians use the term decontamination for methods that reduce the amount of a toxic substance absorbed into the body. Inducing vomiting is one possible form of gastrointestinal decontamination.
For THC exposure, a veterinarian may consider this approach when the ingestion happened recently and the dog still appears completely normal. According to current veterinary guidance, decontamination may be considered within about one hour of THC ingestion in a clinically normal patient.
Timing matters because THC begins moving from the stomach and digestive system into the body after it is swallowed. As more time passes, removing material from the stomach becomes less useful.
The dog’s condition matters just as much as the clock. If the dog is already showing neurological signs, the risks of vomiting may outweigh the possible benefit. Veterinary toxicology guidance also states that patients already showing signs from recreational drugs should first be stabilized before attempts at decontamination are considered.
A veterinarian can decide whether inducing vomiting is appropriate based on the dog’s size, symptoms, time since exposure, product involved, and estimated amount consumed. Veterinary clinics also have medications designed to induce vomiting under controlled conditions when doing so is considered safe.
In some situations, a veterinarian may consider activated charcoal. Activated charcoal can bind certain substances in the digestive tract and reduce their absorption. However, it also has risks and should not simply be given at home. Improper administration can cause complications, especially in a sleepy animal that may inhale the material. Activated charcoal may also cause vomiting, diarrhea, constipation, or changes in blood sodium levels.
Why Owners Should Not Induce Vomiting Without Professional Guidance
Home methods for making dogs vomit can be harmful when used incorrectly. The correct decision depends on the toxin, the dog’s condition, and how much time has passed since the exposure.
Some substances commonly suggested online should not be used at all. Veterinary toxicology guidance specifically advises against methods involving products such as dish soap, mustard, hot sauce, or raw eggs. These substances may cause additional irritation or other complications without safely treating the poisoning.
Hydrogen peroxide has sometimes been used to induce vomiting in dogs, but it should not be treated as a routine home remedy. Giving an incorrect amount or using it in the wrong situation can irritate the stomach and may lead to complications. More importantly, making a dog vomit when it is already sedated or uncoordinated can increase the risk that vomit enters the lungs.
Owners should instead contact a veterinarian as soon as possible and provide clear information about what happened. Useful details include the dog’s weight, the type of cannabis product, the estimated amount eaten, the THC concentration if known, and the approximate time of ingestion.
The product packaging can also be important. Marijuana edibles may contain ingredients that create separate poisoning risks. Chocolate, xylitol, raisins, caffeine, or other ingredients may require different treatment. Knowing exactly what was consumed helps the veterinarian choose the safest approach.
Owners should also be direct about the possibility of marijuana exposure. The purpose of this information is to help the veterinarian make a faster and more accurate treatment decision. Hiding the exposure can delay appropriate care because symptoms such as poor coordination, sleepiness, vomiting, trembling, and abnormal behavior can have many other causes.
Making a dog vomit after marijuana exposure is not automatically the right response. It may sometimes be considered when the ingestion happened very recently and the dog is still completely alert and showing no symptoms. However, the decision should be made with veterinary guidance.
A dog that is already sleepy, stumbling, trembling, weak, or less responsive should generally not be made to vomit because it may not be able to protect its airway. This creates a risk that vomit could enter the lungs and cause serious complications.
Owners should avoid unproven home remedies and contact a veterinarian or animal poison service instead. Early professional advice can determine whether decontamination is still useful or whether supportive care and monitoring are safer. The goal is not simply to remove marijuana from the stomach. The goal is to help the dog recover while avoiding additional harm.
When Is Marijuana Poisoning an Emergency in Dogs?
Marijuana poisoning in dogs can range from mild sleepiness to serious nervous system problems. Many dogs recover with supportive care, but some need urgent veterinary treatment. The level of risk depends on how much THC the dog consumed, the strength of the product, the dog’s size and health, and whether other harmful ingredients were involved.
Dogs can be more sensitive to THC than people. Common effects include extreme tiredness, poor balance, vomiting, trembling, urinary accidents, and unusual reactions to sounds or movement. More serious cases may involve changes in heart rate, body temperature, blood pressure, or breathing. Although death from THC alone is considered extremely rare, serious complications are possible.
Because symptoms can become worse after the initial exposure, owners should not assume that a dog will simply “sleep it off.” If the dog develops severe symptoms or its condition continues to decline, emergency veterinary care is needed.
Emergency Warning Signs
Difficulty breathing is one of the most important warning signs. THC can rarely cause respiratory depression, which means breathing becomes slower or less effective. A dog that is struggling to breathe, breathing very slowly, or showing unusual breathing patterns should receive emergency veterinary care.
A dog that becomes unresponsive or extremely difficult to wake also needs urgent attention. Mild sleepiness is common after cannabis exposure, but a dog should still have some response to its surroundings. A dog that appears unconscious, cannot lift its head, or does not react normally to touch may have more serious poisoning.
Collapse is another emergency sign. THC can affect the nervous and cardiovascular systems. Some dogs may develop low blood pressure or an unusually slow heart rate. These changes can make the dog extremely weak or unable to remain standing.
Severe tremors or seizures also require immediate veterinary treatment. Trembling can occur with THC poisoning, but strong or continuous muscle tremors are more concerning. Seizures are uncommon with marijuana exposure, but they have been reported. A dog having a seizure should be protected from nearby hazards and taken for emergency veterinary care as soon as possible.
Large changes in body temperature are another reason to seek professional help. Some dogs develop hypothermia, meaning their body temperature becomes too low. Hyperthermia, or an unusually high temperature, can also occur. A veterinarian can monitor temperature and provide warming or cooling support when needed.
Repeated vomiting can also become dangerous. Vomiting may lead to dehydration, but there is another concern when a dog is very sleepy or poorly coordinated. If the dog cannot swallow normally, vomit may enter the lungs. This can lead to aspiration pneumonia and other serious breathing problems. For this reason, owners should never try to make a neurologically affected dog vomit unless a veterinarian has specifically instructed them to do so. General veterinary toxicology guidance states that vomiting should not be induced when the swallowing reflex is absent, the animal is neurologically unstable, or there is a high risk of aspiration.
Dogs That May Need Closer Monitoring
Very small dogs may be at greater risk when they consume a cannabis product because a relatively small amount can represent a large dose for their body weight. For example, the same edible that produces moderate effects in a large dog may cause much stronger effects in a small dog.
Puppies also deserve careful attention. Their small body size and developing systems can make accidental ingestion more concerning. Older dogs may also require closer observation, especially if they already have heart, liver, kidney, breathing, or neurologic problems.
The strength of the cannabis product also matters. Modern cannabis products can contain widely different amounts of THC. Concentrates and some edible products may contain much higher levels than plant material. A dog that consumes a concentrated THC product can therefore receive a significant dose from a relatively small amount.
Unknown exposures should also be taken seriously. If an owner does not know how much a dog consumed, it may be difficult to predict how severe the symptoms will become. The veterinarian may recommend observation based on the dog’s symptoms and the suspected product.
Edibles create another concern because THC may not be the only danger. Products can contain chocolate, xylitol, raisins, caffeine, or other substances that are harmful to dogs. In these cases, the veterinarian must consider all possible ingredients rather than treating the exposure as cannabis poisoning alone.
What to Do During Transport
If emergency veterinary care is needed, keep the dog as safe and stable as possible during transportation. A dog affected by THC may be unable to walk normally. Poor coordination can cause the dog to fall from a seat, stumble down steps, or injure itself while trying to move.
Place the dog in a secure area of the vehicle. A carrier may be useful for a small dog. A larger dog can be placed on a flat surface where it is less likely to fall. Keep movement and noise to a minimum because THC can make some dogs unusually sensitive to sound, touch, and motion.
Do not force food or water into the mouth of a dog that is extremely sleepy or unable to swallow normally. Doing so may increase the risk of liquid or food entering the lungs.
Bring the cannabis package with you if it is available. The label may tell the veterinarian the THC concentration, serving size, and other ingredients. If the product was an edible, the ingredient list can be especially useful.
Tell the veterinary team what you believe the dog consumed, how much may be missing, and approximately when the exposure occurred. Accurate information can help the veterinarian decide whether decontamination, monitoring, fluids, medication, or other supportive treatment is appropriate.
There is no benefit in hiding a known cannabis exposure from the veterinarian. The goal is to identify the cause of the symptoms quickly so the dog can receive suitable treatment.
Marijuana poisoning becomes an emergency when a dog develops serious symptoms such as trouble breathing, collapse, severe weakness, unresponsiveness, repeated vomiting, major temperature changes, severe tremors, or seizures. Dogs that cannot stand, swallow normally, or respond to their surroundings also need prompt veterinary assessment.
Very small dogs, puppies, older dogs, dogs with existing health problems, and dogs exposed to concentrated or unknown amounts of THC may require closer monitoring. Edibles can be especially concerning because they may contain other ingredients that are toxic to dogs.
Most dogs with THC poisoning recover with proper supportive care, and serious outcomes are uncommon. However, owners should not try to judge a severe case based only on how “high” the dog appears. When symptoms are intense, worsening, or affecting breathing, consciousness, movement, or other vital functions, immediate veterinary care is the safest response.
How Do Veterinarians Treat a Dog That Is High?
When a dog is affected by marijuana or another product that contains THC, veterinary treatment is based on the dog’s symptoms and the amount of THC that may have been consumed. There is no standard treatment that every dog receives. A dog with mild signs may only need careful monitoring, while a dog with severe symptoms may need hospital care.
THC poisoning in dogs is mainly treated with supportive care. This means the veterinary team helps keep the dog stable and comfortable while its body breaks down and removes the THC. Most dogs recover as the effects of THC wear off. However, close monitoring is important because THC can affect movement, alertness, heart rate, body temperature, and other basic functions.
Initial Veterinary Examination
The veterinarian will usually begin by asking what the dog may have eaten. Owners should provide as much information as possible. This includes the type of cannabis product, the estimated amount consumed, when the exposure happened, and the dog’s weight. If the dog ate an edible, the ingredient list is also important because other ingredients may cause separate health problems.
Owners should be open about a possible marijuana exposure. The information helps the veterinarian make faster and safer treatment decisions. Cannabis poisoning can cause symptoms that are similar to several other medical problems, so knowing about a possible THC exposure can help narrow down the cause.
The veterinarian will also examine the dog’s nervous system and general condition. A dog affected by THC may be very sleepy, unsteady, weak, unusually sensitive to touch, or unable to walk normally. Some dogs may appear restless or confused instead.
Heart rate, breathing, body temperature, hydration, and blood pressure may also be checked. THC can cause changes in several of these areas. The veterinarian may continue checking vital signs every few hours when the dog has noticeable symptoms.
The veterinary team may also look for signs that suggest another toxin or medical condition is involved. This is especially important when the exact substance that the dog consumed is unknown.
Supportive Treatment
Supportive treatment helps maintain normal body functions until the THC has been processed by the dog’s body. The type of care needed depends on the severity of the symptoms.
Fluids may be given under the skin or through an intravenous line. Intravenous fluids can help maintain hydration and normal circulation, especially when a dog is too sleepy or nauseated to drink enough water on its own. Fluid treatment may also be useful when the dog has been vomiting.
Dogs that are nauseated or vomiting may receive anti-nausea medication. This can make the dog more comfortable and reduce continued fluid loss. Veterinarians choose the medication and dose according to the dog’s condition.
Temperature control can also be important. A severely affected dog may have trouble maintaining a normal body temperature. Veterinary staff may use warming or cooling measures depending on the dog’s temperature. This is one reason that severely intoxicated dogs may need to remain in a clinic rather than recover without supervision at home.
A quiet environment is another part of supportive care. Dogs affected by THC can become unusually sensitive to noise, touch, light, or sudden movements. Keeping the patient in a calm area can reduce stress and unnecessary stimulation. Merck Veterinary Manual notes that affected animals can benefit from a low-stimulus environment.
Veterinary staff may also help a weak or unsteady dog move safely. Dogs with poor coordination can fall or injure themselves if they try to walk without assistance. Soft bedding and regular nursing care may be needed when a dog is very sleepy.
Decontamination may sometimes be considered when the exposure happened very recently and the dog is still clinically normal. However, attempts to make a dog vomit are generally avoided once neurological signs such as severe sleepiness or poor coordination have developed because the dog may inhale vomit into its lungs.
Activated charcoal may be used in selected cases to reduce the amount of certain toxic substances absorbed through the digestive system. It is not suitable for every patient. Dogs that are extremely sedated or at high risk of aspiration may not be appropriate candidates unless their airway can be safely protected.
Treatment for More Serious Cases
Dogs with severe THC poisoning may need hospitalization so that their condition can be watched closely. The veterinary team may monitor heart rate, blood pressure, breathing, temperature, and neurological signs.
A very slow heart rate can occur in some dogs with THC toxicity. If it becomes medically significant, a veterinarian may give medication to support the heart rate. Dogs that become unusually agitated may also receive medication to help control severe agitation.
Tremors are less common, but they can occur. Veterinarians can use medications to control significant trembling or muscle activity. Seizures are considered uncommon with THC toxicity, but anticonvulsant drugs may be given if seizures develop.
Breathing must also be watched carefully in dogs that are deeply sedated. General toxicology treatment focuses on maintaining normal respiration, circulation, hydration, and neurological function while the toxic substance is eliminated.
In some severe cases, especially after exposure to a large amount of THC or a highly concentrated cannabis product, a veterinarian may consider intravenous lipid emulsion therapy. This treatment involves giving a special fat solution through a vein. THC is highly fat soluble, and lipid treatment may sometimes help reduce the amount of active drug available to body tissues. It is generally reserved for selected severe cases rather than used routinely for every dog exposed to cannabis.
The length of hospitalization depends on how quickly the dog improves. Some mildly affected dogs may be able to return home after they are stable, able to walk safely, and able to maintain a normal body temperature. More seriously affected dogs may need longer observation.
Veterinarians treat marijuana toxicity in dogs mainly by supporting the dog’s body until the effects of THC wear off. Treatment may include fluids, anti-nausea medicine, temperature support, a quiet environment, and frequent monitoring of vital signs. More serious cases may need hospitalization and medications for abnormal heart rates, agitation, tremors, or seizures.
There is usually no single drug that instantly makes a dog “unstoned.” Instead, treatment focuses on preventing complications and keeping the dog stable while the THC is metabolized. Most cases are expected to improve with appropriate supportive care, and clinical signs commonly resolve within one to three days.
How Long Does It Take for a Dog to Get Unstoned?
When a dog eats marijuana or another product that contains THC, the effects can last much longer than many pet owners expect. A person may feel the effects of cannabis for only a few hours, but dogs can remain affected for much longer. In some cases, signs may continue for one to three days.
The exact recovery time depends on several factors. These include the amount of THC the dog consumed, the strength of the product, the dog’s size, and whether other harmful ingredients were present. Some dogs recover fairly quickly, while others may need a longer period of rest and veterinary care.
There is no safe way to instantly make a dog “unstoned.” Recovery happens as the dog’s body processes and removes the THC. During this time, careful monitoring is important because symptoms can change.
Typical Recovery Time
Many dogs with mild marijuana toxicity begin to improve within several hours. However, it can take much longer for all symptoms to disappear. Some dogs may remain sleepy, unsteady, or less alert for 24 hours or more.
Moderate or severe cases may take one to three days to fully resolve. Dogs that consume a large amount of THC may need even more time. This is especially true if they ate a concentrated cannabis product.
A dog should slowly become more alert as recovery continues. Balance and coordination usually improve over time. The dog may also begin responding more normally to sounds, movement, and people.
Owners should not assume that a dog is fully recovered just because it looks slightly better. A dog may still have poor coordination even after becoming more awake. It may still fall, stumble, or have trouble walking normally.
This is why close supervision is important throughout the recovery period. Dogs should be kept away from stairs, pools, balconies, and other areas where poor balance could cause injury.
Why the Effects Can Last So Long
THC affects the nervous system. Dogs are especially sensitive to its effects. Their bodies may also process THC differently from humans.
THC is stored in body fat and can remain in the body for some time. This can help explain why symptoms may continue even after the dog seems to be improving.
The strength of modern cannabis products can also affect recovery time. Concentrated oils, extracts, and certain edible products may contain much more THC than dried cannabis plant material. A small amount of a strong product can cause noticeable symptoms, especially in a small dog.
Edibles may also take longer to digest. This can delay the start of symptoms and may extend the period during which the dog is affected.
Because of these differences, there is no exact number of hours that applies to every dog.
Factors That Affect Recovery
A dog’s body size can have a major effect on how strongly THC affects it. A small dog that consumes the same amount as a large dog may experience more serious symptoms because the dose is higher compared with its body weight.
The amount of THC is also important. A tiny exposure may cause mild sleepiness, while a larger amount can lead to severe weakness, poor coordination, tremors, or other signs.
THC concentration matters as well. Cannabis flower, gummies, baked goods, oils, and concentrates can contain very different amounts. Some products may contain several doses of THC in a single package.
The type of product can also change the situation. A dog that eats a cannabis brownie, for example, may be exposed to both THC and chocolate. A gummy may contain another ingredient that is unsafe for dogs. Fatty baked goods may also cause digestive problems or contribute to pancreatitis in some dogs.
A dog’s age and general health may affect recovery as well. Puppies, older dogs, and dogs with existing health problems may need closer monitoring. Dogs with heart, breathing, liver, or neurological problems may face additional risks.
What Recovery Usually Looks Like
Recovery from marijuana toxicity is often gradual. A dog may first appear extremely sleepy or unsteady. It may have trouble standing or walking in a straight line.
As the THC wears off, the dog often becomes more alert. It may begin lifting its head, responding to its owner, and moving with better control.
Walking usually becomes steadier over time. A dog that was stumbling may slowly regain normal balance. However, owners should continue to supervise movement until coordination has clearly returned to normal.
Normal eating and drinking may also return gradually. A dog that has been very sleepy may show little interest in food at first. Appetite often improves as alertness increases.
Owners should follow veterinary advice about when to offer food and water. Food or liquids should not be forced into a dog that is extremely sleepy or unable to swallow normally.
Urinary accidents may occur during marijuana intoxication. Some dogs lose bladder control while they are affected. This usually improves as the nervous system returns to normal.
Behavior may also change during recovery. A dog that seemed unusually quiet, nervous, sensitive, or confused should slowly begin acting more like itself.
When Recovery Is Taking Too Long
A dog should receive veterinary attention if symptoms are severe, getting worse, or not improving as expected.
Continued inability to stand, severe shaking, repeated vomiting, trouble breathing, seizures, collapse, or extreme weakness should be treated as urgent warning signs.
Owners should also contact a veterinarian if they are unsure how much cannabis the dog consumed. The same is true if the product contained chocolate, xylitol, caffeine, raisins, medications, or other potentially harmful ingredients.
A dog may appear only mildly affected at first and then become more sedated as more of the product is absorbed. This is one reason why early veterinary guidance is valuable.
Most dogs recover from marijuana toxicity with time and proper care. Mild symptoms may start improving within several hours, but some dogs can remain affected for one to three days. Recovery time depends on the amount of THC consumed, the strength and type of product, the dog’s body size, overall health, and whether other toxic ingredients were involved.
Recovery should usually be gradual. A dog may become more alert, regain better balance, begin eating and drinking normally, and return to its usual behavior as the THC leaves its system. However, the dog should still be supervised until coordination and awareness have fully returned.
There is no instant method for getting a dog unstoned. The safest approach is to follow veterinary advice, provide a secure recovery area, watch for changes, and seek immediate veterinary care if serious symptoms develop.
Are Marijuana Edibles More Dangerous for Dogs?
Marijuana edibles can be more dangerous for dogs than plain cannabis plant material. One reason is that an edible may contain a high amount of tetrahydrocannabinol, or THC, in a small piece of food. THC is the main substance in cannabis that causes intoxication. Dogs can develop signs such as poor balance, extreme sleepiness, trembling, vomiting, and urinary accidents after THC exposure.
Edibles can create another problem because they often contain ingredients that are harmful to dogs on their own. A brownie, cookie, candy, gummy, or other cannabis product may expose a dog to both THC and another toxin at the same time. This means the veterinarian may need to treat more than cannabis toxicity.
For this reason, owners should not focus only on whether their dog appears “high.” They should also find out what else was in the product and tell a veterinarian as soon as possible.
THC Concentration in Edibles
Cannabis edibles may contain concentrated amounts of THC. The exact amount varies widely between products. Some items contain only a small amount per serving, while others may contain much more. A dog that eats several servings can therefore receive a much larger dose than the owner first realizes.
The size of the dog also matters. The same piece of an edible can have a much greater effect on a small dog than on a large dog because the amount of THC is spread across a smaller body weight.
Another difficulty is that dogs do not understand serving sizes. A person may eat one small portion of a cannabis product, but a dog may eat an entire package if it can reach it. This can lead to a much larger exposure.
Veterinary sources report that THC poisoning can cause stomach and nervous system signs, including lethargy, poor coordination, trembling, and urinary incontinence. Most cases improve with supportive treatment, but signs may continue for one to three days.
Concentrated cannabis products may also make it harder for an owner to estimate the dose. If the amount eaten is unknown, it is safer to provide the veterinarian with all available product information rather than trying to estimate the risk at home.
Dangerous Ingredients That May Be Present
THC may not be the only concern in a marijuana edible. Many edible cannabis products are made from foods that can be harmful to dogs.
Chocolate is one important example. Brownies, cookies, chocolate bars, and other cannabis products may contain cocoa. Chocolate contains theobromine and caffeine, which can affect a dog’s nervous system and heart. Large enough exposures can cause vomiting, restlessness, rapid heart rate, abnormal heart rhythms, tremors, and seizures. Dark chocolate and baking chocolate generally contain higher amounts of these substances than milk chocolate.
Xylitol is another serious concern. This sugar substitute may be used in sugar-free candies, baked goods, gums, and other products. In dogs, xylitol can cause a rapid and dangerous drop in blood sugar. Larger exposures can also cause serious liver injury. Signs may include weakness, vomiting, poor coordination, seizures, or collapse.
Some edibles may also contain raisins. Raisins and grapes can cause kidney injury in dogs, and the amount needed to cause toxicity is not easy to predict. This makes any known exposure a reason to contact a veterinarian.
Caffeine may also be present in some chocolate, coffee-flavored, or energy-style products. Caffeine can increase heart rate and stimulate the nervous system. A dog exposed to both THC and caffeine could therefore show a mixture of symptoms.
High-fat foods can create another concern. Many brownies, cookies, and baked edibles contain large amounts of butter or oil. Eating a very fatty food can cause stomach upset and, in some dogs, may contribute to pancreatitis.
Because several ingredients can be involved at once, cannabis edibles can present a more complicated poisoning problem than cannabis alone.
Why the Packaging Matters
If a dog eats a marijuana edible, the product package can give a veterinarian useful information. Owners should save the package rather than throwing it away.
The label may show how much THC is present in each serving and how many servings were in the package. This can help the veterinarian estimate how much THC the dog may have consumed.
The ingredient list is equally important. It can show whether the product contains chocolate, xylitol, raisins, caffeine, or other ingredients that may change the treatment plan.
Owners should also try to determine how much of the product is missing. For example, if a package originally held ten gummies and only four remain, the veterinarian needs to know that as soon as possible.
ASPCA guidance also recommends keeping packaging after a suspected toxic food exposure because ingredients and amounts can help determine the level of risk.
If the original package is not available, owners should still provide any information they know, such as the product name, type of food, approximate amount eaten, and time of ingestion.
Why Edible Exposure Should Be Discussed With a Veterinarian
A dog that eats a cannabis edible should be evaluated based on the whole product, not only the marijuana in it. This is especially important when the ingredients or amount eaten are unknown.
A dog may appear sleepy because of THC while another ingredient is causing a separate medical problem. For example, xylitol can lower blood sugar, while chocolate can affect the heart and nervous system. These problems may need different treatments.
Owners should tell the veterinarian exactly what they believe the dog ate. There is no benefit in hiding cannabis exposure. Accurate information helps the veterinary team decide what tests, monitoring, or treatment may be needed.
Veterinary treatment for THC poisoning is usually supportive. Depending on the dog’s condition, this may include monitoring, fluids, temperature support, and treatment of serious nervous system or heart-related effects. When another toxin is present, however, the treatment may need to address that substance as well.
Owners should also avoid trying to make a sleepy or poorly coordinated dog vomit unless a veterinarian specifically instructs them to do so. A heavily sedated dog may have trouble protecting its airway, which can increase the risk of inhaling vomit.
Marijuana edibles can be more dangerous for dogs than cannabis plant material because they may contain a high amount of THC as well as other harmful ingredients. Chocolate, xylitol, raisins, caffeine, and high-fat foods can add separate health risks to the effects of cannabis.
If a dog eats a marijuana edible, owners should save the package, check the ingredient list, estimate how much was eaten, and contact a veterinarian promptly. They should also report the dog’s approximate weight, the time of exposure, and any symptoms that have appeared.
Can Marijuana Poisoning Kill a Dog?
Marijuana poisoning in dogs is usually treatable, especially when the dog receives proper care. Most dogs recover after the THC leaves their system. However, cannabis exposure should still be taken seriously. A dog can become very sick after eating or inhaling marijuana, and some cases can lead to dangerous complications.
The level of risk depends on several factors. These include the dog’s size, the amount of THC consumed, the strength of the product, and whether other harmful ingredients were also eaten. A small dog that eats a strong cannabis edible may face a much greater risk than a large dog that has a very small exposure.
Dogs do not react to THC in the same way people do. They can become very sleepy, weak, unsteady, or unusually sensitive to sound and touch. In more serious cases, they may have trouble controlling their body temperature, heart rate, breathing, or level of consciousness.
For this reason, owners should not assume that a dog will simply “sleep it off.” Mild cases may improve with careful monitoring, but serious symptoms need veterinary care.
Understanding the Overall Prognosis
The prognosis for most dogs with marijuana toxicity is generally good when they receive the right care. Many dogs begin to improve as their bodies slowly process and remove THC.
The recovery process can take time. Some dogs may appear mildly affected for several hours, while others can show symptoms for one to three days. Strong cannabis products can cause longer-lasting signs.
The amount of THC matters. A small exposure may only cause mild sleepiness and poor balance. A larger exposure can cause deeper sedation, weakness, abnormal heart rate, low body temperature, or other problems.
The type of cannabis product also matters. Modern cannabis concentrates may contain much higher levels of THC than dried plant material. Oils, waxes, gummies, baked goods, and other concentrated products may expose a dog to a larger dose in a small amount of food.
The dog’s body size plays an important role as well. A dose that causes only mild symptoms in a large dog may cause much stronger effects in a small dog or puppy.
Age and general health can also affect recovery. Puppies, senior dogs, and dogs with heart, breathing, or neurological problems may need closer observation.
In many cases, the greatest concern is not THC alone. Cannabis products can contain other ingredients that may be more dangerous than the marijuana itself.
Possible Complications
One possible complication is aspiration. This happens when food, liquid, or vomit enters the lungs instead of going down the esophagus into the stomach.
A dog that is very sleepy or poorly coordinated may not swallow normally. If the dog vomits while heavily sedated, it may breathe some of the vomit into its lungs. This can lead to aspiration pneumonia, which is a serious condition.
Severe sedation is another concern. A mildly affected dog may simply seem sleepy or slow. A more seriously affected dog may become difficult to wake or may respond poorly to touch and sound.
Dogs that become very deeply sedated need careful monitoring because their normal protective reflexes may become weaker.
Respiratory depression can also occur in severe poisoning. This means the dog’s breathing becomes slower or less effective. Any dog that appears to have difficulty breathing, very slow breathing, blue or pale gums, or extreme weakness needs emergency veterinary care.
Body temperature can also change. Some dogs develop a lower-than-normal temperature because THC affects the nervous system. A dog that is very cold may need controlled warming under veterinary supervision.
Heart rate changes are possible as well. Some dogs develop a slower heart rate, while others may develop changes in blood pressure. These effects are one reason veterinarians may monitor the heart and circulation in more serious cases.
Another risk comes from poor coordination. Dogs affected by THC may stumble, fall, or struggle to stand. A dog can injure itself by falling down stairs, walking into furniture, or jumping from a bed or couch.
Keeping the dog in a safe, low area can help prevent these injuries while recovery is taking place.
Why Edibles Can Be More Dangerous
Cannabis edibles may create risks beyond THC poisoning. The other ingredients in the food can sometimes be toxic to dogs.
Chocolate is a common example. Some brownies, cookies, candies, and baked goods contain both marijuana and chocolate. Chocolate contains substances called theobromine and caffeine, which can be harmful to dogs.
The danger depends on the type of chocolate, the amount eaten, and the dog’s body weight. Dark chocolate and baking chocolate usually contain higher amounts of theobromine than milk chocolate.
Some cannabis candies or baked products may also contain xylitol. Xylitol is an artificial sweetener that can be extremely dangerous to dogs. It can cause a rapid drop in blood sugar and may also lead to liver damage.
Other edibles may contain raisins, caffeine, large amounts of fat, or other ingredients that can cause additional problems.
High-fat foods may increase the risk of pancreatitis in some dogs. Pancreatitis is inflammation of the pancreas and can cause vomiting, stomach pain, loss of appetite, and weakness.
Because of these added risks, owners should always tell the veterinarian exactly what product the dog ate. Bringing the package or ingredient list can be very useful.
Why Serious Symptoms Should Never Be Ignored
There is an important difference between a dog that is mildly sleepy and a dog showing signs of a medical emergency.
A mildly affected dog may seem tired, walk slowly, or appear slightly uncoordinated. The dog may still respond normally when called, breathe comfortably, and remain aware of its surroundings.
A more seriously affected dog may become difficult to wake, collapse, have repeated vomiting, develop tremors, or have trouble breathing. These signs need immediate veterinary attention.
Seizures should always be treated as an emergency. Although seizures are not the most common sign of cannabis poisoning, they can occur in severe cases or when another toxic substance is also involved.
Repeated vomiting is another warning sign. Vomiting can lead to dehydration and can also increase the risk of aspiration if the dog is very sleepy.
Owners should also seek urgent veterinary care if the dog cannot stand, becomes unresponsive, appears extremely cold, has very slow or abnormal breathing, or shows a major change in heart rate.
It is also important to remember that the exact amount of THC eaten is not always known. A dog may eat more than the owner realizes, especially if a package was damaged or part of the product is missing.
When the amount is uncertain, it is safer to contact a veterinarian rather than assume the exposure was small.
Can THC Alone Be Fatal to a Dog?
Death caused only by marijuana exposure appears to be uncommon in dogs. Most animals recover when they receive appropriate supportive care.
However, this does not mean marijuana is harmless to pets.
Very high doses can cause serious nervous system depression and other complications. Concentrated THC products may also expose dogs to much larger amounts than traditional cannabis plant material.
The risk becomes greater when other toxic ingredients are involved. A dog that eats a cannabis brownie, for example, may be affected by both THC and chocolate. A sugar-free cannabis edible may contain xylitol, which can create a separate and potentially life-threatening emergency.
Severe dehydration, aspiration pneumonia, injuries from falls, abnormal body temperature, and breathing problems can also make the situation more dangerous.
For these reasons, every suspected cannabis exposure should be evaluated based on the specific dog and the specific product involved.
Owners should never hide the fact that marijuana may have been involved. Veterinarians need accurate information to choose the safest treatment. Veterinary professionals are focused on treating the animal and identifying the cause of the symptoms.
Marijuana poisoning is rarely fatal in dogs, and most dogs recover with proper care. However, serious complications are possible, especially after a large exposure or when strong THC concentrates or harmful edible ingredients are involved.
Problems such as severe sedation, aspiration, breathing difficulty, abnormal body temperature, heart rate changes, repeated vomiting, seizures, and injuries from poor coordination can make the condition more serious.
Cannabis edibles deserve extra caution because they may contain other toxic substances such as chocolate, xylitol, raisins, or caffeine.
A dog that is only mildly sleepy may recover with veterinary guidance and careful monitoring. A dog that collapses, cannot stand, has trouble breathing, becomes unresponsive, has seizures, or repeatedly vomits needs immediate veterinary care.
Most dogs have a good outcome when the exposure is recognized early and the right supportive treatment is provided.
How Can You Keep a Dog Safe While Recovering From Cannabis Toxicity?
A dog recovering from cannabis toxicity may seem sleepy, weak, confused, or unsteady for many hours. Some dogs may also react strongly to sounds, movement, or touch. Because of these effects, recovery care should focus on safety, comfort, and close monitoring.
Most dogs recover well with proper supportive care. However, signs can sometimes last from one to three days, depending on the amount of THC consumed, the strength of the product, and the dog’s size and health. Mild cases may sometimes be monitored at home after a veterinarian has decided that the dog is stable enough to leave the clinic.
Create a Quiet Recovery Area
A dog recovering from marijuana exposure should have a calm and secure place to rest. THC can make dogs more sensitive to sound, movement, and touch. A loud room with children, other pets, music, or constant activity may make the dog more anxious or confused.
Choose a quiet room where the dog can sleep without being disturbed. Keep the lights comfortable and limit unnecessary handling. A soft bed placed directly on the floor is usually safer than a couch, chair, or raised dog bed.
Dogs affected by THC may have poor balance, also known as ataxia. They may sway, stumble, or fall when they try to walk. For this reason, stairs should be blocked. The dog should also be kept away from balconies, swimming pools, open doors, and other places where a fall could cause injury.
A low-stimulation environment is also part of veterinary supportive care for THC toxicity. Keeping the surroundings calm can help reduce stress while the dog’s nervous system returns to normal.
Supervise Movement
Do not assume that a dog can walk safely just because it is awake. A dog under the effects of THC may look alert but still have poor muscle control and balance.
Watch the dog closely whenever it stands or walks. If it needs to go outside to urinate or defecate, keep the trip short and controlled. A leash can help prevent the dog from wandering, falling, or suddenly moving into an unsafe area.
Avoid long walks, running, stairs, jumping, and active play until normal coordination has returned. Do not encourage the dog to climb onto beds, sofas, or other furniture. A dog that normally jumps without difficulty may misjudge the distance while intoxicated and fall.
Some dogs with marijuana toxicity may also leak urine or urinate without realizing it. This is a recognized sign of THC exposure and does not mean the dog has forgotten its house training. Placing washable bedding or absorbent pads beneath the dog can make cleanup easier during recovery.
Food and Water During Recovery
Food and water should be handled carefully while the dog is still very sleepy or poorly coordinated. A dog must be alert enough to swallow normally before eating or drinking safely.
Do not force water into the dog’s mouth with a syringe, bottle, or other device. Do not force-feed a dog that is very drowsy. If swallowing is weak, food or liquid could enter the airway instead of the stomach. This can lead to aspiration, which can cause serious lung problems.
The safest approach is to follow the veterinarian’s instructions about when food and water should be offered. Once the dog is alert, able to stand more normally, and swallowing without difficulty, small amounts of water may be offered if the veterinarian approves.
Food can usually be introduced gradually as the dog’s condition improves. If the dog is nauseated or vomiting, a veterinarian may recommend waiting before feeding or may prescribe medication to control nausea. Veterinary treatment for symptomatic THC exposure can include fluids and anti-nausea medication when needed.
Never give human medications, supplements, oils, stimulants, or other substances in an attempt to make the dog sober faster unless a veterinarian has specifically instructed you to do so.
Continue Monitoring the Dog
Even when a dog is allowed to recover at home, observation is important. Symptoms should gradually improve rather than become more severe.
Watch how alert the dog is. It may sleep more than usual, but it should eventually become easier to wake and more responsive. Pay attention to walking and balance as well. Coordination should slowly return as the THC leaves the body.
Breathing should remain steady and comfortable. Severe breathing changes are uncommon, but respiratory depression has been reported with serious THC poisoning. Dogs can also develop slow heart rates, low blood pressure, or problems controlling body temperature.
Contact a veterinarian promptly if the dog becomes difficult to wake, cannot stand, has repeated vomiting, develops severe tremors, has a seizure, struggles to breathe, or appears to be getting worse instead of better. Seizures and severe complications are uncommon, but they require professional treatment.
Urination should also be monitored. Temporary urinary incontinence can occur with cannabis toxicity. Keep the dog clean and dry if accidents happen, and provide regular opportunities to go outside once walking becomes safe.
Recovery may not be immediate. According to the Merck Veterinary Manual, clinical signs usually resolve within one to three days. A dog may therefore remain tired or mildly unsteady even after the strongest effects have passed.
Prevent Future Marijuana Exposure
Once the dog has recovered, preventing another exposure is important. Cannabis products should be treated much like medications and kept where pets cannot reach them.
Store cannabis flower, gummies, baked goods, oils, concentrates, and other THC products in closed containers inside secure cabinets. Leaving them on countertops, coffee tables, nightstands, or inside easily opened bags can put dogs at risk.
Edibles can be especially attractive because they may smell like normal food. Some also contain ingredients that create additional dangers for dogs. Chocolate, raisins, caffeine, and the artificial sweetener xylitol can all cause separate forms of poisoning.
Trash also needs to be secured. Dogs may eat discarded cannabis material, wrappers, leftover edibles, or other products from an open garbage can. Visitors should also know that cannabis products must be kept away from pets.
The ASPCA recommends keeping marijuana and THC products securely out of reach because pets can easily find edible products through their strong sense of smell.
Keeping a dog safe during recovery from cannabis toxicity mainly involves preventing injury and watching for changes in its condition. Provide a quiet place on the floor, block access to stairs and other hazards, and supervise the dog whenever it walks. Avoid strenuous activity until normal coordination has returned.
Food and water should only be offered when the dog is alert enough to swallow safely and according to veterinary guidance. Never force-feed a very sleepy dog or give home remedies in an attempt to remove THC from its system faster.
Continue watching the dog’s alertness, breathing, balance, vomiting, urination, and overall behavior. Most dogs recover with supportive care, and signs commonly improve within one to three days. However, worsening symptoms, breathing problems, seizures, severe weakness, or loss of consciousness require immediate veterinary attention.
Conclusion: Helping a Dog Recover Safely From Marijuana Exposure
When a dog eats marijuana or another product that contains THC, the most important step is to stay focused on safety. There is no quick home remedy that can instantly make a dog “unstoned.” The effects of THC have to wear off as the dog’s body processes and removes the drug. Treatment is mainly supportive, which means keeping the dog stable and treating problems that appear while the THC leaves the body. Most dogs recover well with proper care, and clinical signs often improve within one to three days.
Owners should act as soon as they suspect that a dog has eaten cannabis. Try to identify what the dog consumed, how much may be missing, and when the exposure happened. Keep the package or label if one is available. This information can help a veterinarian understand the possible dose and the level of risk. Products can have very different amounts of THC, so knowing whether the dog ate dried cannabis, an edible, an oil, or a concentrated product can make a difference.
It is also important to watch for early signs of THC toxicity. A dog may become very sleepy, weak, or unsteady. It may stumble when walking or have trouble standing. Other possible signs include vomiting, trembling, dilated pupils, unusual sensitivity to sound or touch, slow heart rate, low body temperature, or loss of bladder control. More serious exposures may cause severe weakness, agitation, seizures, breathing problems, or loss of consciousness.
A veterinarian should be contacted when marijuana exposure is known or strongly suspected, especially if the dog is already showing symptoms. Owners should be open about what the dog may have eaten. The goal is to help the veterinary team choose the safest treatment. Important details include the dog’s weight, the name of the product, its THC strength if known, the estimated amount eaten, and the time of exposure.
Owners should not try to make a dog vomit unless a veterinarian or veterinary poison expert specifically recommends it. Inducing vomiting may sometimes be considered shortly after an ingestion if the dog is still alert and neurologically normal. However, vomiting can be dangerous once a dog is sleepy, unsteady, or unable to swallow normally. In that condition, vomit can enter the lungs and lead to aspiration pneumonia. Veterinary guidance lists neurologic problems and a high risk of aspiration as reasons not to induce vomiting.
There is also no safe household trick that can quickly reverse the effects of THC. Owners should avoid giving human medications, stimulants, oils, milk, salt, or other unproven treatments. These methods may not help and could cause new health problems. A veterinarian can decide whether the dog needs fluids, medicine for vomiting, temperature support, seizure control, or closer monitoring. Dogs with more serious symptoms may need to stay at a veterinary hospital until their condition improves.
Edibles need special attention because THC may not be the only concern. A brownie, cookie, candy, or other edible may contain ingredients that are harmful to dogs. Chocolate, xylitol, raisins, caffeine, and other substances can create separate poisoning risks. High-fat foods may also cause digestive problems in some dogs. For this reason, owners should tell the veterinarian exactly what type of edible was consumed and provide the ingredient list when possible.
During recovery, a dog should be kept in a calm and safe area. THC can affect balance and coordination, so stairs, high furniture, balconies, pools, and other hazards should be blocked. A soft resting place on the floor can reduce the chance of injury. Noise, bright activity, and unnecessary handling should also be limited because some affected dogs become very sensitive to sound or touch.
Food and water should be handled carefully. Owners should follow the veterinarian’s instructions instead of forcing a very sleepy dog to eat or drink. A dog that cannot swallow normally could inhale food or liquid into the lungs. As the dog improves, normal interest in food, water, movement, and its surroundings should gradually return.
Continued monitoring is important even after the dog begins to look better. Owners should watch the dog’s breathing, ability to walk, alertness, vomiting, urination, and overall behavior. Clinical signs commonly resolve within one to three days, although the length of recovery depends on the amount consumed, the product involved, and how severely the dog was affected.
Emergency veterinary care is especially important if a dog becomes unconscious, has trouble breathing, has a seizure, repeatedly vomits, cannot stand, or becomes extremely weak. Severe changes in heart rate or body temperature can also require treatment. While deaths from THC exposure are described as extremely rare, serious complications can occur, especially after exposure to large amounts, concentrated products, or foods that contain other toxic ingredients.
Prevention is the safest approach. Cannabis flower, gummies, baked goods, oils, concentrates, and other THC products should be stored like medications. They should be placed in secure containers and kept inside cabinets or other areas that dogs cannot reach. Bags, countertops, bedside tables, trash cans, and outdoor areas should also be checked because dogs may find products that people assume are safely out of the way. The ASPCA recommends keeping marijuana and THC products securely out of pets’ reach.
In most cases, a dog exposed to marijuana can recover with proper monitoring and supportive care. The key is not to search for a fast way to make the dog sober. Instead, identify the exposure, contact a veterinarian, avoid unsafe home treatments, watch closely for serious symptoms, and give the dog a safe place to recover. With prompt attention and suitable veterinary care when needed, the prognosis for THC toxicity in dogs is generally good.

Questions and Answers
Q1: How can I get my dog unstoned?
There is no safe home remedy or instant way to make a dog unstoned. If you suspect THC or marijuana exposure, contact a veterinarian or animal poison service as soon as possible. Treatment usually focuses on monitoring and supportive care while the dog’s body removes the THC.
Q2: What should I do first if my dog ate marijuana?
Remove your dog from the source, prevent any more exposure, and identify what was eaten and how much if possible. Keep the product packaging and contact a veterinarian promptly, even if your dog seems normal at first.
Q3: What are the signs that a dog is high from marijuana?
Common signs include wobbling, unusual sleepiness, dilated pupils, urine dribbling, vomiting, sensitivity to sound or touch, and changes in heart rate or body temperature. Severe poisoning can cause seizures, collapse, breathing problems, or coma.
Q4: How long does it take for a dog to recover from being high?
Recovery time depends on the amount and concentration of THC, the dog’s size, and the type of product involved. Some dogs may recover within about 18 to 36 hours, while signs can sometimes last longer after larger exposures.
Q5: Can I make my dog vomit after eating marijuana?
Do not try to make your dog vomit unless a veterinarian specifically tells you to do so. A dog that is already sleepy, uncoordinated, or neurologically affected may inhale vomit into the lungs, creating another serious problem.
Q6: Can a dog die from marijuana poisoning?
Most marijuana exposures are not fatal, but serious poisoning is possible, especially with large amounts or highly concentrated THC products. Severe cases may involve low blood pressure, seizures, breathing problems, aspiration, coma, and, rarely, death.
Q7: Should I take my dog to the vet if it is high?
Yes, you should at least contact a veterinarian promptly for guidance. Immediate emergency care is especially important if your dog has seizures, collapses, becomes unconscious, has trouble breathing, or shows severe weakness.
Q8: What will a veterinarian do for a dog with marijuana toxicity?
Treatment depends on the severity of the poisoning. A veterinarian may provide IV fluids, temperature control, anti-vomiting medication, heart and blood pressure monitoring, oxygen, and other supportive treatment. Severe cases may require hospitalization or breathing support.
Q9: Are marijuana edibles more dangerous to dogs?
They can be. Edibles may contain concentrated THC, and dogs may eat several servings at once. Some edible products can also contain other dangerous ingredients, such as chocolate, which can add another source of toxicity.
Q10: Can I let my dog sleep off a marijuana high at home?
Do not simply assume the dog can sleep it off. Contact a veterinarian first because the correct response depends on the amount consumed, the dog’s condition, and any other ingredients involved. A veterinarian may sometimes recommend home monitoring for mild cases, but more serious symptoms require veterinary treatment.
