Is My Dog High From Weed? Signs of THC Exposure, What to Do, and When to Go to the Vet

Many people use the phrase “high” when they think a dog has been exposed to weed. In plain terms, this usually means the dog has taken in THC, the main chemical in cannabis that causes mind and body effects. Dogs can be exposed in several ways. They may eat an edible like a gummy, brownie, cookie, or chocolate. They may chew on dried plant material, such as buds or a joint left within reach. Some dogs get into stronger forms, like oils, vape liquids, wax, or “dabs.” In some homes, a dog may also breathe in smoke or vapor in a small room. No matter how it happens, the result can look scary, because dogs do not understand what is happening to them and cannot tell us how they feel.

This guide is written for one main reason: when you suspect THC exposure, it helps to stay calm and act in a clear order. Dogs often recover well with the right care, but some situations can become serious fast. The goal is not to shame anyone or to guess what “should” have happened. The goal is to help you notice the signs early, protect your dog from harm, and know when professional help is needed. Weed products today can be much stronger than many people expect, especially concentrates and some edibles. That strength matters because a small dog can be affected by a small amount, and a medium or large dog can still be in danger if the product is potent enough.

It also helps to understand why dogs may seem more affected than people. Dogs have different body sizes, different metabolism, and different sensitivity to THC. A dose that seems “small” to a person may be a big dose for a 10-pound dog. Some dogs are also more sensitive than others, even at the same weight. Age and health can matter too. Very young dogs, older dogs, and dogs with heart, liver, or brain problems may have a harder time handling intoxication. Another issue is that dogs explore with their mouths. They do not stop at “one bite” the way a person might. If they find a bag of gummies, they may eat many at once before anyone notices.

This article will guide you through the most important steps, in the order you need them. First, you will learn how to spot common signs of THC exposure. These signs can include a wobbly walk, acting “spacey,” being unusually sleepy, or reacting in odd ways to sound and touch. Some dogs drool, vomit, or lose bladder control. A few show more severe signs, like shaking, extreme weakness, or seizures. Knowing these signs matters because THC exposure can look like other problems, such as low blood sugar, poisoning from other household items, or even a brain issue. You do not need to diagnose the cause at home, but you do need to recognize that something is wrong and respond quickly.

Next, you will learn about timing. Many owners ask, “How fast will this start?” and “How long will it last?” The answers depend on what the dog was exposed to. Inhaled smoke or vapor can act faster, while edibles often take longer to show effects and may worsen over time. Some dogs seem okay at first and then become very unsteady or very sleepy later. Knowing this helps you decide whether it is safe to watch at home or whether you should go in right away. It also helps you plan for monitoring, because some dogs need a quiet, safe space for many hours, and sometimes longer.

You will also get clear guidance on what to do right away. That includes moving your dog to a safe area, preventing falls, keeping them calm, and gathering useful information for a veterinarian. If you have the packaging, the label can tell you the THC amount per piece and the total amount in the product. That information can be very helpful. You will also learn what not to do. Many people search for quick fixes, like making a dog vomit or giving home remedies. These steps can be risky, especially if your dog is very sleepy or uncoordinated. In those cases, vomiting can lead to choking or aspiration, which is when vomit is breathed into the lungs.

Finally, this guide will explain when to call a vet and when to go to an emergency clinic. Some symptoms are always urgent, like trouble breathing, seizures, collapse, or being unable to wake your dog normally. Other signs may still need same-day advice because dogs can get worse, and some products contain other dangerous ingredients, like chocolate or certain sweeteners. The safest approach is simple: if you are not sure, call a veterinarian or an animal poison hotline for guidance. A short phone call can help you choose the right next step for your dog’s safety.

Even though this topic can feel stressful, there is a practical path forward. You do not need perfect information to take smart action. If you suspect THC exposure, focus on safety, observe your dog closely, and seek professional advice early. This article is meant to help you do that with clear steps, plain language, and a calm plan.

Quick emergency check: Is this a “go now” situation?

When you think your dog may be high from weed (THC), the first goal is simple: figure out if your dog needs emergency care right now. Some dogs only seem sleepy or wobbly and recover with support. Other dogs can become very sick fast, especially after edibles or concentrates. This section will help you spot the danger signs and choose the safest next step.

Step 1: Look for “go now” red flags (emergency signs)

If you see any of the signs below, do not wait. Go to an emergency vet right away or call your nearest emergency clinic while you are on the way.

Seizures or severe shaking

A seizure may look like stiff legs, paddling, collapsing, or loss of control.
Some dogs have strong tremors (shaking that does not stop).
These signs can be life-threatening and need urgent care.

Trouble breathing

Fast, hard breathing, loud breathing, or struggling to breathe is an emergency.
If your dog’s gums look pale, gray, or blue, treat it as urgent.
Breathing problems can happen if your dog is too sedated or if vomit is inhaled.

Your dog cannot stand, keeps falling, or seems “not there”

Mild wobbling can happen with THC, but not being able to walk at all is more serious.
If your dog collapses, cannot sit up, or seems unaware of you, get help now.
Deep sedation can lead to choking or breathing issues.

Repeated vomiting or signs of choking

One vomit can happen, but repeated vomiting is a bigger risk.
A very sleepy dog may vomit and accidentally inhale it into the lungs. This is called aspiration, and it can cause pneumonia.
If your dog is gagging, coughing after vomiting, or making wet breathing sounds, go now.

Extreme body temperature changes

If your dog feels very hot or very cold, that can be serious.
You may notice heavy panting (too warm) or shivering and weak movement (too cold).
Vets can check temperature and give safe support.

You suspect a high-potency product

Vape oils, dabs, wax, or strong edibles can contain much more THC than dried plant material.
If you think your dog got into a concentrate, treat it as urgent even if signs are mild at first.

Step 2: Know the “call now” signs (urgent, but not always ER)

If your dog is awake and breathing normally, but has these signs, you should call your vet, an emergency clinic, or an animal poison hotline right away. The goal is to get guidance and decide if your dog should be seen today.

Common urgent signs include:

Wobbly walking, stumbling, or acting dizzy
Very sleepy, slow to respond, or “spaced out”
Wide eyes, glassy eyes, or pupils that look larger than normal
Drooling a lot
Urine accidents or dribbling urine (many owners notice this with THC)
Restlessness, whining, or acting unusually anxious
Mild vomiting with otherwise stable breathing

Even if these signs seem mild, your dog may worsen over the next hours, especially after edibles. A phone call early can prevent problems later.

Step 3: Use a simple decision guide (Call first vs Go now)

Use these questions to guide your next move:

Go now if:

Your dog has any red-flag signs listed above.
Your dog is very small, very young, very old, or has heart/lung disease.
You do not know what or how much was eaten.
You suspect concentrates or strong edibles.
Symptoms are getting worse quickly.

Call first (but do it right away) if:

Your dog is awake, breathing normally, and can stand.
Symptoms are mild to moderate and not getting worse fast.
You know the product and amount and can share details.
You can watch your dog closely while you get advice.

If you call, be ready to share:

Your dog’s weight, age, and health issues
The time you think exposure happened
The product type (gummy, brownie, joint, oil, vape)
The THC amount on the label (mg per piece) and how much might be missing
Current symptoms and when they started

Step 4: Make your dog safer while you decide

Whether you are calling or heading to the vet, make your dog safer right away:

Prevent falls: Block stairs and keep your dog on the floor, not on furniture.
Keep it calm: Quiet room, dim lights, low noise.
Do not force food or water: A sleepy dog can choke.
Watch breathing: Count breaths if you can and note changes.
Bring packaging: Take the label or container to the vet if possible.

If your dog has seizures, breathing trouble, collapse, repeated vomiting, or severe confusion, go to an emergency vet now. If signs are milder (wobbly, sleepy, drooling, urine accidents), call a vet or poison hotline right away for the next steps. When it comes to THC exposure, acting early is the safest choice.

Can dogs get high from weed? What THC does in a dog’s body

Yes—dogs can get “high” from weed. When people say a dog is “high,” they usually mean the dog has been exposed to THC, the main chemical in cannabis that causes intoxication. Dogs do not experience THC the same way humans do. Even a small amount can cause clear, sometimes scary signs in a dog.

What THC is, in plain terms

Cannabis (also called marijuana or weed) contains many chemicals. The two most talked-about ones are:

THC (tetrahydrocannabinol): the part that can cause a “high,” meaning changes in the brain and nerves.
CBD (cannabidiol): a different cannabis chemical that does not cause a “high” in the same way.

When a dog eats or breathes in THC, it can affect the dog’s brain, balance, heart, and digestion. The effects may look like illness, poisoning, or even a stroke. That is why it is important to take the situation seriously and contact a veterinarian.

How THC gets into a dog’s system

A dog can be exposed in a few main ways:

Eating cannabis products (most common)

This includes edibles like gummies, cookies, brownies, chocolates, candies, and butter or oil used in cooking.
This is often the most risky type because edibles can contain high amounts of THC and may also contain other harmful ingredients, like chocolate.

Eating plant material

This includes dried “buds,” joints, or leftover pieces.
Plant material may have less THC than concentrates, but it can still cause signs, especially in small dogs.

Eating or licking concentrates

Concentrates include oils, wax, “dabs,” vape cartridges, and some tinctures.
These products can be very strong. A small amount can lead to bigger problems.

Breathing in smoke or vapor

Secondhand smoke exposure is possible, though it may cause milder signs than eating an edible.
However, a small dog in a closed room with heavy smoke can still be affected.

What THC does inside the body (why the signs happen)

THC works by attaching to special “switches” in the body called receptors. These receptors are part of the endocannabinoid system, which helps control things like mood, movement, appetite, and alertness. Dogs have these receptors too. The big difference is that THC may affect dogs more strongly, especially in the brain.

When THC reaches the brain and nervous system, it can interfere with normal signals that control:

Balance and coordination (leading to wobbling or falling)
Alertness (leading to sleepiness or being “out of it”)
Body control (leading to dribbling urine or accidents)
Temperature regulation (some dogs get too cold or too warm)
Heart rate and blood pressure (may go up or down)

These effects can look sudden and intense, which is why many owners think something else is happening, such as a seizure disorder or a toxin exposure. In a way, it is a toxin exposure—because THC is not meant for dogs, and it can disrupt normal body function.

Why dogs may react more than humans

Many people wonder, “If this amount doesn’t bother me, why is my dog acting so strange?” There are a few simple reasons:

Body size matters. A gummy with 10 mg of THC may be mild for an adult human, but for a 10-pound dog, it is a much higher dose per pound.
Dogs are more sensitive. Dogs can show strong neurologic signs like wobbling, confusion, and urine accidents.
Edibles are unpredictable. Some edibles are much stronger than they look. Homemade foods can be especially hard to judge.
THC is stored in fat. THC is fat-soluble, meaning the body can hold onto it longer. This can make signs last longer than people expect.

CBD vs THC: an important clarification

CBD products are often sold for humans and sometimes marketed for pets. CBD is not supposed to cause the classic “high.” But there are important cautions:

Some products labeled “CBD” may still contain THC, especially if quality control is poor.
A dog may also react to other ingredients in the product, even if THC is low.
Because labels and dosing can be confusing, it is safest to treat any cannabis product exposure as potentially serious until a vet says otherwise.

Dogs can get “high” from weed because THC affects their brain and nervous system. Dogs may react strongly due to their smaller size, higher sensitivity, and the high potency of many edibles and concentrates. THC can change balance, alertness, urination, temperature, and heart function. If you suspect THC exposure, treat it as a real medical concern and contact a veterinarian for guidance.

Common sources of exposure: What dogs get into most often

When people say a dog is “high from weed,” they usually mean the dog has been exposed to THC, the chemical in cannabis that causes intoxication. Dogs can be exposed in several ways. Knowing the most common sources helps you figure out what happened, how serious it might be, and what details to share with a vet.

Edibles: gummies, baked goods, chocolates, and candies

Edibles are one of the most common causes of THC exposure in dogs. They often smell and taste good to pets, so dogs may eat them quickly and in large amounts. Edibles also come in many forms, including:

Gummies and chewy candies
Cookies, brownies, cakes, and other baked goods
Chocolate bars, chocolate cookies, or chocolate brownies
“Butters” and oils used for cooking (like cannabis butter)

Edibles can be extra risky for two main reasons:

First, the THC dose can be high. Some products contain a lot of THC in one piece. For example, a single gummy or cookie can contain more THC than a small dog can handle. Dogs do not understand “one serving,” so they may eat the whole package.

Second, edibles may include other ingredients that are dangerous to dogs. Chocolate is a big example. Chocolate can poison dogs on its own, even without THC. Some sugar-free products may contain xylitol (a sweetener that can be very dangerous for dogs). Not every edible contains xylitol, but it can show up in certain candies, gums, baked goods, or “sugar-free” items. This is why the exact product label matters.

Edibles can also be tricky because symptoms may start later than you expect. When THC is eaten, it has to move through the stomach and intestines first. That delay can make owners think the dog is fine—until symptoms suddenly appear or worsen.

Plant material: buds, joints, “shake,” and leftover scraps

Some dogs get exposed when they eat cannabis plant material, such as:

Loose buds or dried flower
Pre-rolled joints or blunts
“Shake” (small pieces left in a bag or container)
Leftovers dropped on the floor, couch, or bed
Stash found in a backpack, purse, or jacket pocket

Plant material may seem less dangerous than edibles, but it can still cause strong symptoms—especially in small dogs. It may also be hard to estimate how much was eaten. A dog might chew and swallow quickly, or scatter it around, so you cannot always tell what is missing.

Another issue is that joints or blunts may include paper, filters, or tobacco. These add more problems. Chewed paper can upset the stomach. Tobacco and nicotine can be toxic. If you suspect a dog ate something mixed with tobacco, treat it as urgent and call a vet right away.

Concentrates: oils, wax, dabs, and vape cartridges

Concentrates are products with very high THC strength. They can cause more serious symptoms because the THC amount per drop or bite may be large. Dogs may be exposed through:

THC oils or tinctures
Wax, shatter, or “dabs”
Vape cartridges, pods, or disposable vapes
THC liquids used for vaping

These products can be dangerous for two reasons:

They are very concentrated, meaning a small amount can be a big dose. Also, vape cartridges and devices contain parts that can be chewed and swallowed. This can create choking risk or stomach blockage. Some cartridges may also leak sticky oil, which can coat the mouth and be hard to remove.

If you find a chewed cartridge, keep it and bring it to the vet if you go in. The vet may use it to estimate the risk.

Secondhand smoke: being near smoke or vapor

Dogs can also be exposed by breathing smoke or vapor in an enclosed space. This can happen when:

A person smokes in a small room with the dog
A dog sits in a car where cannabis is being smoked
A dog is close to someone vaping THC indoors

Secondhand exposure may cause mild signs, but it can still be a problem—especially for small dogs, older dogs, or dogs with heart or lung disease. Also, if a dog is sleepy or unsteady after being in a smoky room, it can be hard to know whether it was only inhalation. Sometimes, the dog may also have eaten something without the owner noticing.

Bonus risk: other toxins that come with cannabis products

A key point is that cannabis is not always the only danger. Some products come with extra risks, such as:

Chocolate in brownies, cookies, or bars
Xylitol in certain sugar-free items
Alcohol in some homemade foods or drinks
Caffeine in chocolate or energy-style edibles
Fatty foods (like butter-heavy baked goods), which can trigger stomach upset in some dogs

These ingredients can change what symptoms look like and how urgent the situation is. That is why you should gather details like the brand, THC amount per serving, and ingredient list if you can do so safely.

Dogs most often get THC exposure from edibles, plant material, concentrates, or secondhand smoke. Edibles and concentrates are usually the most concerning because they can contain a high THC dose, and edibles may also include other toxic ingredients like chocolate or xylitol. If you suspect exposure, save the packaging, estimate what is missing, and contact a vet or emergency clinic with those details.

Signs your dog may be “high”: symptom checklist (organized and easy to scan)

If a dog has been exposed to THC (the part of cannabis that causes a “high”), the signs are usually easy to spot once you know what to look for. Many dogs seem “drunk” or “out of it.” Some look sleepy and calm, while others become restless and confused. Symptoms can start mild and then get worse, especially if your dog ate an edible, because edibles take longer to digest.

Below is a clear checklist of the most common signs. Not every dog will show every sign. A dog may have only a few mild symptoms, or several symptoms at once.

Movement and coordination problems (wobbliness)

One of the most common clues is a change in how your dog walks and stands.

Wobbly walking (ataxia): Your dog may sway, stumble, or walk like they are off balance.
Trouble standing: They may spread their legs wide to keep from falling.
Weakness: Some dogs act like their legs are “not working right,” especially the back legs.
Falling or tipping over: They might misjudge steps, bump into furniture, or fall when turning.
Slow reactions: Your dog may take longer to respond when you call them or touch them.

Why this happens: THC affects the brain and nervous system. That can change balance, muscle control, and reaction time.

Safety tip: If your dog is wobbly, block stairs and keep them on one level of your home. A fall can cause injuries.

Behavior and awareness changes (confusion or “not themselves”)

THC often changes how alert your dog seems.

Confusion: Your dog may look lost, stare at walls, or seem unsure where they are.
Disorientation: They may pace, walk in circles, or get “stuck” in corners.
Sleepiness or heavy sedation: Some dogs become very drowsy and want to lie down.
Restlessness or agitation: Others do the opposite—pant, pace, whine, or seem unable to settle.
Unusual vocalizing: Some dogs whine, bark, or howl for no clear reason.
Startle easily: Normal sounds may scare them, and they may jump or flinch.

Why this happens: THC changes how the brain processes signals. Your dog may feel overwhelmed, confused, or very tired.

What this can look like at home: A dog may not come when called, may not want to play, or may act “spaced out.” You might feel like your dog is awake but not fully present.

Eye and mouth changes (a helpful clue)

Changes in the eyes and mouth often show up with THC exposure.

Glassy or dull eyes: The eyes may look shiny or unfocused.
Dilated pupils: The black centers of the eyes may look larger than normal.
Odd eye movements: In some dogs, the eyes may flick or move strangely.
Drooling: Your dog may drool more than usual, sometimes a lot.
Lip smacking: Some dogs lick their lips repeatedly, which can go with nausea.

Why this happens: THC can affect nerves that control the eyes and also cause nausea and drooling.

Stomach and gut signs (especially with edibles)

If your dog ate cannabis—especially an edible—stomach problems may happen.

Vomiting: This can occur once or many times.
Nausea: Your dog may look uncomfortable, drool, swallow a lot, or refuse food.
Diarrhea: Not all dogs get diarrhea, but it can happen.

Important: Edibles may contain other ingredients that upset the stomach. Some can be dangerous on their own. For example, chocolate can be toxic to dogs. That means an “edible” exposure may be more serious than THC alone.

Urination changes (accidents or dribbling)

Urinary issues are very common with THC exposure and can be a strong clue.

Accidents in the house: A potty-trained dog may suddenly pee indoors.
Dribbling urine: Some dogs leak urine without realizing it.
Needing to pee more often: Your dog may ask to go out more than usual.

Why this happens: THC can relax muscles and affect nerve signals. Your dog may not have normal bladder control for a while.

Body changes you may notice (breathing, temperature, heart rate)

Some changes are subtle and may be easier for a vet to measure, but owners can still notice some of them.

Panting: Your dog may pant even when it is not hot.
Shaking or trembling: Mild tremors can happen.
Too cold or too warm: Some dogs feel cooler than normal, or they may seem overheated.
Fast or slow heart rate: You may not measure this at home, but you might notice weakness or unusual calmness.

These signs matter because they can point to a stronger exposure, especially if your dog is very small or ate a high-potency product.

Serious signs: when it may be severe

Most THC exposures cause mild to moderate signs, but serious signs can happen. These need urgent veterinary care.

Seizures: Full-body shaking that your dog cannot stop.
Collapse: Your dog cannot stand at all.
Very slow breathing or trouble breathing: Breathing looks weak, slow, or strained.
Unresponsive or hard to wake: Your dog does not react to your voice or touch.
Repeated vomiting: This raises the risk of dehydration and aspiration (breathing vomit into the lungs).

If you see any of these, treat it as an emergency.

Dogs exposed to THC often look wobbly, confused, very sleepy, or unusually restless. You may also notice glassy eyes, drooling, vomiting, and urine accidents. Mild signs can still worsen over time, especially after edibles. If your dog has seizures, collapse, trouble breathing, cannot wake up normally, or keeps vomiting, seek emergency veterinary care right away.

Timing: How fast symptoms start and how long they last

When a dog is exposed to THC (the main “high” chemical in marijuana), one of the first questions people ask is: “How long until I see signs?” The answer depends on how your dog was exposed, how much they got, and your dog’s size and health. Some dogs look “off” quickly. Others seem normal at first, then get worse later. Understanding timing helps you know what to watch for and when to call for help.

How fast symptoms can start

THC can enter a dog’s body in different ways. The route matters because it changes how fast THC reaches the brain.

Inhaled exposure (smoke or vapor)

If a dog breathes in marijuana smoke or vapor, signs can start fairly fast, sometimes within minutes to about an hour.
Inhaled THC moves from the lungs into the bloodstream quickly.
Even if signs start fast, they can still change over the next few hours, especially if the dog stays in a smoky area.

Eaten exposure (edibles, plant material, oils, concentrates)

If a dog eats THC, the body must digest it first. That usually means slower onset.
Signs often start in 30 minutes to 2 hours, but it can take longer.
With some edibles, especially high-fat foods or baked goods, signs may be delayed to 3 hours or more.
This delay can trick people into thinking the dog is fine. Then symptoms suddenly appear or become stronger.

Why edibles often get worse over time
Edibles can “stack” in the body. That means the dog may still be absorbing THC while you are watching them. A dog might start with mild sleepiness, then later become very wobbly, confused, or unable to walk normally. This is one reason veterinarians take edible exposures seriously, even if the dog looks okay at first.

What affects the start time

Even with the same product, two dogs can show signs at different times. Common reasons include:

Dose (how much THC): Higher amounts usually cause signs sooner and more strongly.
Potency: Concentrates and oils can contain much more THC than plant material.
Stomach contents: A dog that ate THC on an empty stomach may show signs faster. A full stomach can slow digestion, delaying signs.
Dog size: Smaller dogs can become affected with less THC, and signs may be more noticeable.
Age and health: Older dogs or dogs with liver disease may process THC more slowly, leading to longer-lasting effects.
Other ingredients: Chocolate, certain sweeteners, or alcohol (in rare cases) can add extra risks and may change symptoms and timing.

How long a dog can stay “high”

The next big question is: “How long will this last?” There is no single number that fits every case. But many dogs show signs for several hours, and some can remain affected for a full day or longer.

Mild exposures may improve within 6 to 12 hours.
Moderate cases may last 12 to 24 hours.
Some dogs can show signs for 24 to 72 hours, especially after large edible doses or very strong products.

This longer timeline happens because THC is fat-soluble, meaning it can be stored in body fat and released slowly. Also, when THC is eaten, the liver processes it. In some cases, that process can create effects that last longer than people expect.

What “improving” usually looks like

Recovery is often gradual. You may notice:

The dog becomes less sleepy and more alert.
Walking becomes steadier.
The dog stops having urine accidents.
Appetite and normal behavior return slowly.

A dog may seem better, then look a bit worse again after a nap. That can happen because THC effects can rise and fall as the body processes it. This does not always mean an emergency, but it is a reason to keep close watch.

When timing becomes a warning sign

Timing can also tell you when the risk is higher.

Go to a vet or emergency clinic right away if:

Symptoms are getting worse after the first hour or two.
Your dog cannot stand, seems very confused, or is hard to wake up.
There is repeated vomiting, shaking, tremors, or any seizure.
You suspect a high-potency product (oil, wax, vape cartridge, gummies with high THC).
You do not know what was eaten or how much is missing.

If you are not sure, it is safest to call a vet. The sooner you call, the more options they may have to help.

THC timing in dogs depends on the exposure type. Inhaled THC can cause signs quickly, sometimes within minutes. Eaten THC, especially edibles, can take longer to show signs and may worsen over several hours. Many dogs improve within 12 to 24 hours, but some can stay affected for up to 72 hours, especially after strong products or large amounts. If your dog’s signs are severe, getting worse, or you suspect a high dose, treat it as urgent and contact a veterinarian or emergency clinic right away.

How dangerous is it? “Can THC kill my dog?” and what raises the risk

THC (the chemical in marijuana that causes a “high”) can make dogs very sick. Many dogs recover with the right care, but THC exposure is still serious. The danger depends on how much THC your dog got, what type of product it was, and how your dog’s body reacts. Some dogs look “drunk” and sleepy and get better in a day or two. Others can become so weak and confused that they cannot protect their airway, cannot walk, or cannot control their body temperature. Those cases need emergency help.

What “dangerous” really means

When people ask “How dangerous is this?” they often mean one of two things:

Can this cause life-threatening symptoms?
Yes. A dog can develop severe signs like extreme sleepiness, collapse, tremors, or seizures. A dog can also vomit and accidentally breathe vomit into the lungs (this is called aspiration). Breathing vomit into the lungs can cause pneumonia, which can become life-threatening.
Can THC kill a dog by itself?
Most dogs do not die from THC exposure, especially when they get help quickly. But it can happen, especially with very high doses or very strong products. Also, the biggest danger is not always the THC alone. It can be the problems that come with it—like choking, aspiration, injury, or other toxins mixed into the edible.

Why small dogs are at higher risk

A small dog needs far less THC to become very sick. For example, one gummy or one brownie might be a mild problem for a large dog, but a major emergency for a 5-pound dog. Dogs also do not understand what is happening. They may panic, stumble, or fall. If a small dog becomes very weak, it can cool down too much or overheat, depending on the room and activity. Small dogs also have less body reserve, so they can get into trouble faster.

Products that raise the risk: edibles and concentrates

Not all cannabis products carry the same risk.

Edibles are often more dangerous than plant material because:

They can contain a high dose of THC in a small bite.
The effects can be delayed, so signs may worsen over time.
They often contain other ingredients that are harmful to dogs.

Concentrates (like oils, wax, “dabs,” or vape cartridges) are especially risky because:

They can have very high THC levels.
A small amount can cause strong effects.
Dogs may lick or chew containers, which makes it hard to know how much they swallowed.

The hidden danger: other toxins in edibles

Many people focus only on THC. But some edibles have ingredients that can be dangerous on their own. Two important examples are:

Chocolate: Chocolate can poison dogs. Dark chocolate and baking chocolate are the worst. If a dog eats a marijuana brownie, there may be two problems at once—THC intoxication and chocolate poisoning.
Sugar alcohols (like xylitol): Some candies and baked goods use sugar substitutes. Xylitol can cause a dangerous drop in blood sugar and can harm the liver. Not every edible has xylitol, but if it does, it becomes a true emergency.

Because of these added risks, it is important to tell the vet exactly what your dog ate, not just “weed.”

How THC causes serious problems

THC affects the brain and nerves. This can cause:

Poor balance and slow reflexes: Your dog may fall, hit furniture, or tumble down stairs.
Severe sleepiness: Your dog may be too sleepy to swallow well or protect their airway.
Changes in heart rate and blood pressure: Some dogs may have a fast heartbeat, others may have a slow one. Either can be concerning if the dog is weak or unstable.
Body temperature problems: Some dogs get too cold, others get too warm. Both can be dangerous if not corrected.
Tremors or seizures (in severe cases): These are urgent signs.

Delayed discovery makes it worse

The earlier you get help, the better. If you find out right away, a vet may be able to reduce how much THC gets absorbed. If you discover it hours later, more THC may already be in your dog’s system. This can mean stronger signs and a longer recovery time.

Dogs with higher risk even at lower doses

Some dogs can become very sick with smaller amounts, including:

Very young puppies
Senior dogs
Dogs with heart disease, lung disease, liver disease, or kidney problems
Dogs taking medicines that cause sleepiness

These dogs may not handle the effects as well and may need vet care sooner.

When THC exposure becomes an emergency

Go to an emergency vet right away if you see:

Seizures, repeated tremors, or collapse
Trouble breathing, choking, or loud snoring when your dog is not normally a snorer
Extreme sleepiness (hard to wake), or your dog cannot stand or walk
Repeated vomiting or signs of severe distress
You suspect a high-potency product (concentrate, vape oil, many edibles)
You are not sure what your dog ate, how much, or when

THC exposure in dogs can range from mild to life-threatening. The biggest risks happen with high doses, strong products (especially concentrates and edibles), small dogs, and delayed treatment. The danger also increases when edibles include other toxins like chocolate or xylitol. If your dog is very weak, vomiting repeatedly, having tremors or seizures, or struggling to breathe, treat it as an emergency and get veterinary care right away.

What to do right now at home (first steps, in order)

If you think your dog got into weed or a THC edible, it’s normal to feel scared. The most helpful thing you can do is act in a calm, organized way. These steps are meant to keep your dog safe and help a vet give the right advice as fast as possible.

Step 1: Remove your dog from the source and prevent more exposure

First, stop your dog from getting any more THC.

Move your dog to a safe room away from the area where the product was found. Close doors or use a baby gate.
Pick up and secure anything left behind: gummies, brownies, plant material, vape pens, cartridges, oils, wrappers, and crumbs. Dogs will often go back for seconds if they can.
Check the floor and low surfaces. Look under couches, tables, beds, and around trash cans. Small pieces can still cause symptoms, especially in small dogs.
Secure the trash. If your dog got it from the garbage, take the bag outside or put it in a locked bin. Many “second exposures” happen when a dog returns to the trash later.

If you have other pets, keep them away too. More than one pet can be affected if the product was shared, dropped, or spilled.

Step 2: Make the space safe so your dog doesn’t get hurt

THC can make dogs clumsy, sleepy, or confused. Even if the exposure seems mild, accidents can happen.

Block stairs and balconies. A wobbly dog can fall easily.
Keep them on one level of the home if you can.
Remove hazards like sharp furniture edges, slippery rugs, and items your dog could bump into.
Dim the lights and lower noise. Some dogs get more sensitive to sound or movement. A quiet space can reduce stress.
Do not let your dog jump on furniture. If your dog wants to rest, set up a soft bed on the floor.
Supervise closely. A dog that is very sleepy may vomit and inhale it into the lungs. If your dog seems deeply sedated, keep them in a position where their airway stays clear and watch their breathing.

If your dog is very wobbly, use a leash for short potty trips. Walk slowly and stay close to support them.

Step 3: Do a quick, simple symptom check

You do not need special tools. You just need to observe.

Look for:

Wobbly walking, falling, or weakness
Extreme sleepiness or trouble staying awake
Unusual behavior (confusion, staring, acting “spaced out”)
Vomiting
Tremors or shaking
Accidents or dribbling urine
Breathing changes (very slow, very fast, or struggling)
Seizures (body stiffening, jerking, loss of awareness)

If you see seizures, collapse, or breathing trouble, treat it as an emergency. Go to an emergency vet right away.

Step 4: Gather key information before you call (it saves time)

The faster you can give clear details, the faster a professional can help. Take a deep breath and collect what you can.

What product was it?

Edible (gummy, cookie, brownie, chocolate, candy)
Plant material (buds, joint)
Oil/concentrate (vape oil, tincture, wax)

How much THC might be in it?

Look at the label for “THC mg” per piece and per package.
If it’s homemade or unlabeled, write down what you know (for example: “one brownie missing” or “half a cartridge chewed”).

How much is missing?

Count pieces left, check wrappers, look for bite marks.
Even a rough estimate helps.

When did it happen?

Give the best time window you can: “within the last 30 minutes” or “sometime in the last 2 hours.”

Your dog’s details

Weight (even an estimate)
Age (puppy, adult, senior)
Health issues (heart disease, seizures, liver or kidney problems)
Current medications

Current symptoms and how they are changing

What you see right now
Whether symptoms are getting worse, better, or staying the same

If possible, take a photo of the product label. Bring the packaging to the vet. This can be one of the most helpful things you do.

Step 5: Call for professional help right away

Even if your dog seems “okay,” it is still smart to call. THC effects can show up later, especially after edibles.

Call your regular vet if they are open.
If not, call a 24/7 emergency vet clinic.
You can also call an animal poison control hotline if you cannot reach a clinic quickly or if the clinic tells you to. (They may charge a fee, but they can give very specific guidance.)

Be honest about what happened. The goal is to help your dog, not to judge you. Clear information helps the vet decide if your dog can be watched at home or needs care right away.

Step 6: Follow the advice you are given and prepare for transport if needed

If the vet says to come in:

Keep your dog warm and calm during the ride.
Use a leash or carrier so they don’t stumble or jump.
Bring the packaging or a photo of the label.
Do not give food, treats, or human medicines unless a vet tells you to. Some products can make vomiting more likely, and some medicines can cause harm.

If the vet says to monitor at home, follow their instructions closely and keep watching for changes.

If you suspect THC exposure, act in this order: stop more exposure, prevent falls and injuries, check symptoms, gather product details, and call a vet or emergency clinic right away. Fast, calm action is the best way to protect your dog and get the right help.

Should I Make My Dog Throw Up? What NOT to Do (and What to Do Instead)

If you think your dog ate weed or a THC edible, your first instinct might be to “get it out” right away. Many people search for how to make a dog throw up at home. But with THC exposure, making your dog vomit can be risky, especially if your dog is already acting “high.” A safer plan is to call a veterinarian or an animal poison hotline first, then follow their instructions.

Why you should not induce vomiting without a vet’s guidance

Vomiting is not always safe for dogs. When a dog is affected by THC, they may be:

very sleepy
confused or disoriented
wobbly on their feet
slower to swallow normally

These problems matter because vomiting requires good coordination. If your dog vomits while very sleepy or unsteady, they can breathe vomit into their lungs. This is called aspiration, and it can lead to serious lung infection or trouble breathing. Aspiration can become an emergency even if the THC exposure itself was mild.

Inducing vomiting can also cause:

choking
severe stress and panic
worsening dehydration (if vomiting continues)
throat irritation or injury, depending on what was used

Because of these risks, do not try to make your dog throw up unless a vet tells you to and confirms it is safe based on your dog’s current condition.

Why timing matters (and why “just do it now” is not always correct)

Even when vomiting is an option, timing is important. In many poison cases, a vet might only consider inducing vomiting if:

the exposure was recent (often within a short window), and
the dog is alert and can swallow normally, and
the product is something that can come back up safely.

With THC, the situation is trickier. Some THC products, especially edibles, may already be partly digested by the time you notice symptoms. Also, THC can slow a dog’s reflexes. That makes vomiting less safe.

This is why you should focus first on getting professional advice instead of trying a quick home fix.

Do not use dangerous “home remedies”

Online tips can be harmful. Do not give your dog:

hydrogen peroxide to force vomiting unless a vet specifically tells you the correct dose and confirms it’s safe
salt (this can cause dangerous salt poisoning)
oil, butter, or milk to “dilute” THC (it does not cancel THC and can upset the stomach)
human anti-nausea drugs, pain medicine, or sleep aids (many are toxic to dogs)
coffee, energy drinks, or caffeine (caffeine can be dangerous and can worsen anxiety and heart issues)

These options can turn a treatable situation into a much more serious one.

What about activated charcoal?

Activated charcoal is sometimes used by vets to help bind certain toxins in the gut. Many people wonder if they can buy it and give it at home. In most cases, activated charcoal should be vet-directed, not a do-it-yourself step.

Here’s why:

The correct dose depends on your dog’s weight and the product eaten.
It can be unsafe if your dog is very sleepy, because they could inhale it.
It can cause vomiting or constipation, which may complicate recovery.
It does not “reverse” THC right away. It is only one tool, and it works best in certain situations and time frames.

A vet may recommend it, give it at the clinic, or tell you not to use it at all. The best move is to ask first.

What you should do instead (clear steps)

If you suspect THC exposure, do these steps in order:

Remove access right away.
Pick up any remaining edibles, buds, oils, wrappers, or packaging. Keep them out of reach.
Check your dog’s current state.
Is your dog alert? Can they stand? Are they breathing normally? Are they vomiting?
Call for professional help.
Call your regular vet if open. If not, call an emergency vet or an animal poison hotline. Be ready to share:

your dog’s weight, age, and any health problems
what product it was (gummy, brownie, vape oil, flower, etc.)
how much might be missing
the THC amount listed on the package (mg per piece and total mg)
when you think it happened
what symptoms you see right now

Keep your dog safe while you wait.
Put them in a quiet, dim room. Block stairs. Keep them warm and supervised. Offer small sips of water only if they are fully awake and can swallow normally.
Follow the plan you are given.
If the vet says to come in, go in. If they say to monitor at home, ask what signs mean you should leave for the clinic.

Do not try to make your dog throw up after weed exposure unless a vet tells you to. THC can make dogs sleepy and unsteady, and vomiting can lead to choking or aspiration. Avoid risky home remedies, and do not give activated charcoal unless a professional recommends it. The safest path is to call a vet or emergency clinic quickly, share the product details, and follow their instructions while keeping your dog calm and protected from falls.

When to Go to the Vet (and When to Go Straight to an Emergency Clinic)

If you think your dog ate weed or a THC edible, it is always safer to call a vet right away, even if the signs seem mild. Dogs can get worse over time, especially after eating edibles. Some products also contain other ingredients that are toxic to dogs. The goal is to figure out how serious it is, and how fast your dog needs help.

Go to an emergency clinic right now (do not wait)

Go straight to an emergency vet if you notice any of these signs. These can mean your dog’s brain and body are too affected to stay safe at home:

Seizures or repeated tremors (shaking you cannot stop)
Collapse or your dog cannot stand up
Very slow, very fast, or irregular breathing
Trouble breathing, noisy breathing, or blue/gray gums
Unresponsive behavior, like your dog will not wake up or cannot focus at all
Severe confusion, panic, or agitation that you cannot calm
Repeated vomiting, especially if your dog is weak or sleepy
Very low body temperature (your dog feels cold, is weak, and is not acting normal)

These signs can lead to dangerous problems like choking on vomit, injury from falling, or not getting enough oxygen. An emergency clinic can monitor your dog closely and treat problems quickly.

Go urgently today (same day), even if it does not seem “life or death”

Some dogs look “high” but are still awake and breathing normally. Even then, you should see a vet the same day if any of the points below apply:

Your dog is very wobbly or keeps falling
Your dog is very sleepy and hard to keep awake
Your dog has urine accidents plus wobbliness or confusion
Your dog is acting “off” and is getting worse over the next hour
You do not know how much your dog ate
Your dog may have eaten a high-potency product (vape oil, wax, dabs, concentrates)
Your dog is small, especially toy breeds (small bodies are affected faster)
Your dog is very young, very old, pregnant, or has heart, liver, kidney, or brain disease

A same-day exam matters because some dogs look mild at first, then become very sleepy or start vomiting. A vet can decide if your dog needs fluids, nausea medicine, or close monitoring.

Treat it as “must go” if edibles may contain other toxins

Many “weed snacks” have ingredients that are dangerous for dogs even without THC. This is one reason vets want to know what the product was.

Go to the vet right away if your dog ate:

Chocolate brownies, cookies, or candy
Gum or candy that might contain xylitol (a sugar substitute that can be deadly)
High-fat baked goods (can trigger stomach upset and may raise the risk of pancreas problems)
Products mixed with alcohol or other drugs

Even if the THC amount is low, these other ingredients can cause serious illness. This is also why it helps to bring the package, wrapper, or photo of the label.

When it may be okay to monitor at home (only after you call)

Sometimes a dog has very mild signs, like slightly sleepy behavior, and you know the amount was tiny. In some cases, a vet may say you can watch your dog at home. But you should still call first. Home monitoring may be reasonable if:

Your dog is awake, can walk safely, and is not vomiting
Breathing is normal and steady
You know the product and the amount was small
Your dog has no major health problems
You can watch your dog closely for several hours

Even then, you should be ready to go in if your dog gets worse.

What to tell the vet (this helps them decide fast)

When you call or arrive, share clear details. This can change treatment choices:

Your dog’s weight, age, and health problems
Time of exposure (about when you think it happened)
Type of product (flower, edible, vape oil, gummy, brownie)
THC amount on the label (mg per piece) and how many pieces are missing
Current signs: wobbling, sleepiness, urine accidents, vomiting, tremors

If you feel nervous about admitting exposure, remember this: the vet’s main job is to treat your dog. Clear information can help your dog get the right care faster.

If your dog may be high from weed, call a vet right away. Go to the emergency clinic immediately for seizures, collapse, breathing problems, repeated vomiting, or extreme sleepiness. Go urgently the same day if your dog is very wobbly, getting worse, or you do not know how much they ate. Treat edibles with chocolate or possible xylitol as a must-go situation. When in doubt, it is better to be checked than to wait.

What the vet will do: diagnosis and treatment (what to expect)

When you arrive at the clinic, the vet’s main goal is to keep your dog safe while the THC leaves their system. Many dogs recover well with the right care, but the plan depends on how much was eaten or inhaled, what kind of product it was, and how your dog is acting right now.

What information the vet will ask for (and why it matters)

The vet team will likely ask questions right away, even before the full exam, because the details help them choose the safest treatment.

They may ask:

What was it? (gummy, brownie, plant material, vape oil, concentrate, etc.)
How much is missing? (one gummy vs a whole bag, a bite vs a full brownie)
How strong is it? (the THC amount in milligrams, if you know)
When did it happen? (time matters for decontamination steps)
How big is your dog? (weight helps estimate risk)
What symptoms do you see? (wobbling, vomiting, sleepiness, tremors, etc.)
Any other health problems or medicines? (some conditions raise risk)

If you have the package or label, bring it. The label can show the THC dose per piece and other ingredients. This is important because some edibles also contain things that are toxic to dogs, like chocolate or certain sweeteners.

The physical exam: what they check first

After a quick history, the vet will examine your dog and measure key body functions. This helps them judge how serious the exposure is and what support your dog needs.

Common checks include:

Temperature (too low or too high can happen with intoxication)
Heart rate and rhythm (some dogs have a slow or fast heart rate)
Breathing rate and effort (to make sure breathing stays safe)
Blood pressure (THC can affect it in some cases)
Neurologic status (how alert your dog is, how they walk, pupil size, reflexes)

They will also look for signs that your dog might vomit and inhale vomit (called aspiration). This risk is higher if your dog is very sleepy or cannot swallow normally.

Testing: what may be done (and what tests can’t always tell)

In many cases, the vet can strongly suspect THC exposure based on the story and symptoms. Still, they may do tests to rule out other problems or to check safety before treatment.

Possible tests include:

Bloodwork to check blood sugar, organ function, and hydration status
Electrolytes to look for imbalances, especially if vomiting happened
A basic urine test to check overall health and hydration

Some clinics may use a urine drug screen (like the type used for people). It can sometimes help, but it is not perfect in dogs. A test may be negative even when THC exposure is real, or it may not match the timing of symptoms. Because of this, vets usually treat based on your dog’s condition, not just a test result.

Decontamination: removing what has not been absorbed yet

If the exposure was recent and your dog is still alert enough, the vet may consider steps to reduce how much THC the body absorbs.

This might include:

Inducing vomiting (only if it is safe). The clinic may do this early on, but they will avoid it if your dog is too sleepy, has poor coordination, or is at risk of inhaling vomit.
Activated charcoal in selected cases. Charcoal can bind some toxins in the gut. It is not right for every dog, and timing matters. The vet decides based on the product, the time since exposure, and your dog’s alertness.

These steps are done under supervision because they can cause side effects, like vomiting, dehydration, or aspiration, especially in a sedated dog.

Supportive care: the most common and most important treatment

There is no simple “antidote” that instantly reverses THC. So treatment is mainly supportive care, meaning the vet supports your dog’s body until the drug wears off.

Supportive care can include:

IV fluids to prevent dehydration, support blood pressure, and help the body process and eliminate the drug
Anti-nausea medication if vomiting is present or likely
Warming or cooling support if body temperature is abnormal
Quiet, padded confinement to prevent injuries from wobbling or confusion
Monitoring of heart rate, blood pressure, and breathing, especially for moderate to severe cases

Dogs that are very wobbly may need help standing and walking. Dogs that are very sleepy may need careful monitoring so they do not fall, choke, or become too cold.

Severe cases: when hospitalization and intensive care are needed

Some dogs need stronger support, especially if they ate a large amount or a high-potency product.

In severe cases, a vet may provide:

Oxygen support if breathing is slow or weak
Medications for tremors or seizures if they occur
More frequent monitoring, sometimes in an ICU setting
Airway protection in extreme sedation (rare but possible)

Some hospitals may consider intravenous lipid emulsion (ILE) in certain severe exposures. This is a type of fat-based fluid that can sometimes help with toxins that dissolve in fat. It is not used for every case, and the vet will decide if it fits your dog’s risk level and symptoms.

Will the vet “report” me if my dog ate weed?

Many owners worry about being judged or getting in trouble. In most situations, the clinic’s focus is medical care and safety. The most helpful thing you can do is be honest about what your dog may have been exposed to. Clear information helps the vet choose the right treatment and avoid unsafe steps.

At the vet, you can expect quick questions, a focused exam, and close monitoring. Treatment is usually supportive, and many dogs improve with time and care. The clinic may also try to reduce absorption if the timing is right and it is safe. The most important takeaway is this: early contact with a vet often leads to safer care and a smoother recovery, especially for small dogs, strong edibles, or severe symptoms.

Recovery and aftercare at home (next 24–72 hours)

Most dogs that have been exposed to THC start to improve within a day, but it can take longer for some dogs. You may see signs for 24 to 72 hours, especially if your dog ate an edible or a high-potency product. During this time, your main goals are simple: keep your dog safe, watch for changes, and follow your vet’s instructions closely.

What recovery can look like (and what may still be normal)

As your dog recovers, signs often fade slowly instead of all at once. You may notice:

Sleepiness or “zoning out.” Your dog may rest more than usual and respond slowly when you call their name.
Wobbly walking. Your dog may look unsteady, like they are slipping or drifting to one side.
Extra sensitivity. Some dogs seem startled by normal sounds or lights.
Urine accidents. Your dog may leak urine or have trouble controlling their bladder.
Mild stomach upset. Some dogs may drool or feel nauseous. Some may vomit, especially early on.

These signs can be expected during recovery, but they should gradually improve. If your dog stays the same for many hours, or suddenly gets worse, that is a sign to call a vet.

Set up a safe recovery space in your home

THC can affect balance and awareness. That raises the risk of falls and injuries. Create a calm “recovery zone” for at least the first day:

Choose a quiet room away from loud TV, kids running, or other pets that may stress your dog.
Block stairs and slippery floors. Use baby gates, close doors, and lay down rugs or towels to prevent slipping.
Use soft bedding in a spot where your dog can rest without needing to climb on furniture.
Keep the room dim if your dog seems sensitive to light.
Supervise closely. Do not leave a very sleepy or wobbly dog alone for long periods.

If your dog is very unsteady, consider keeping them on one floor only and limiting movement until they can walk normally.

Potty breaks: keep them short and controlled

Many dogs need help during bathroom breaks because they may stumble or squat awkwardly.

Use a leash, even in a fenced yard, so your dog does not fall, wander, or get stuck.
Go slowly. Let your dog take short steps and avoid slick areas.
Stay close. If your dog starts to tip over, you can support them.
Expect accidents. If your dog dribbles urine or has an accident indoors, stay calm. Clean up well and keep your dog comfortable. This often improves as the THC wears off.

If your dog cannot stand to pee or poop, or seems painful, call your vet.

Food and water: small amounts and common sense

Follow your vet’s advice first. If your dog is at home and alert enough to swallow safely:

Offer fresh water. Start with small sips. Do not force water into the mouth.
Delay food if your dog is nauseous. If your dog has been vomiting, your vet may suggest waiting before feeding.
When you do feed, start small. Offer a small meal of your usual food, or a bland option if your vet recommends it.
Watch swallowing and gagging. A very sedated dog may not swallow well. If your dog seems too sleepy to eat or drink safely, call your vet.

Never give human medicines unless a veterinarian tells you to. Some human drugs can be dangerous for dogs.

Home monitoring checklist (what to watch and how often)

Check your dog often during the first 12–24 hours, then as needed as they improve. Write notes if it helps. Look at:

Walking and balance: Are they less wobbly than before?
Alertness: Do they wake up easily? Do they know who you are?
Breathing: Is it smooth and regular, not labored or noisy?
Vomiting: Is it stopping, or happening again and again?
Hydration: Are they drinking some water? Are gums moist, not sticky?
Urination: Can they pee? Are they leaking urine?
Temperature and comfort: Do they feel unusually cold or very hot? Are they trembling?

A good sign is steady improvement every few hours.

When to re-contact the vet right away

Call your veterinarian or an emergency clinic if any of these happen:

Your dog becomes hard to wake, collapses, or cannot stand.
Your dog has tremors or seizures.
Your dog has trouble breathing or seems to gasp.
Vomiting is repeated, violent, or your dog cannot keep water down.
Your dog seems to be getting worse instead of better.
You suspect your dog ate an edible with chocolate or other harmful ingredients, even if THC signs seem mild.

If you are unsure, it is safer to call. It is always easier to treat problems early.

Recovery at home is mostly about safety and careful watching. Keep your dog in a quiet space, prevent falls, use a leash for potty breaks, and offer water and food only when your dog is alert enough. Most dogs improve with time and supportive care, but worsening signs, repeated vomiting, breathing problems, or seizures are emergencies. When in doubt, contact your vet or an emergency clinic for guidance.

Prevention: keeping cannabis products away from pets

Preventing THC exposure is much easier than treating it. Dogs are curious, fast, and food-driven. Many cannabis products smell interesting to them, especially edibles that contain sugar, butter, meat flavors, or chocolate. A dog can find a dropped gummy or an open backpack in seconds. The goal is to remove easy access, reduce accidents, and make sure everyone in the home follows the same safety habits.

Store cannabis like medicine, not like snacks

Treat cannabis products the way you would treat prescription pills. That means storing them in a place your dog cannot reach, even if they jump, climb, or knock things over.

Use a locked space. A closed drawer is not enough for many dogs. Use a locked cabinet, a lockbox, or a high cupboard with a child safety lock.
Keep it out of “dog-height” zones. Many dogs can reach countertops, coffee tables, nightstands, and bathroom trash cans. If your dog can put their paws on it, they can probably reach it.
Store it in its original package when possible. Many legal products come in child-resistant packaging. Keep it sealed. Do not move gummies or baked goods into easy-open plastic bags.
Separate products from food. Do not store edibles near candy, treats, flour, or baking supplies. If it lives with snacks, it is easier to grab the wrong item and easier for the dog to find.

A good rule: if a toddler could get it, your dog probably can too.

Use sealed containers and label clearly

Even with good storage, accidents happen during daily use. Sealed containers add one more layer of protection.

Choose a hard container with a tight lid. A glass jar with a strong lid or a hard plastic container is better than a thin bag.
Label the container clearly. Write “THC” or “Cannabis—Not for Pets” on the container. This helps other adults in the home, babysitters, and older kids.
Avoid loose items. Loose pre-rolls, roaches, and leftover edibles are easy to drop. Keep them contained. Small pieces are harder to notice on the floor.

Party and guest safety: backpacks, purses, and pockets

Many dog exposures happen when a visitor brings cannabis into the home. Dogs often sniff bags, jackets, and purses, especially if they smell food.

Create a “bag zone.” Ask guests to place backpacks and purses on a high shelf, in a closet, or in a closed room.
Check coat pockets. A small gummy or chocolate can fall out of a pocket when someone sits down or hangs up a jacket.
Be careful with overnight guests. Guests may keep items on a bedside table or in luggage. Remind them to store products safely, just like medication.

If you feel awkward bringing it up, keep it simple: “My dog gets into things, so please keep any cannabis products locked up or out of reach.”

Trash control after use: wrappers and leftovers matter

Dogs often get exposed from the trash, not from the product itself. Wrappers can smell like candy or butter. Used vape cartridges or leftover baked goods can still contain THC.

Use a lidded trash can. Choose a can with a tight lid or a step pedal lid that your dog cannot pry open.
Take trash out quickly. If you used cannabis at a gathering, don’t leave wrappers and leftovers overnight.
Do not leave food scraps on counters. Brownies, cookies, and gummies should never sit out, even “for a minute.”
Be careful with outdoor bins. Dogs sometimes get into a garage bin or an outdoor trash bag. Keep bins closed and secure.

Smoking and vaping around pets: reduce the chance of exposure

Secondhand smoke exposure is usually less severe than eating edibles, but it can still affect pets. Smoke and vapor can irritate the airways. Dogs may also lick residue from fur, furniture, or floors.

Do not smoke or vape in enclosed spaces with pets. Small rooms, cars, and bathrooms concentrate smoke and vapor.
Ventilate well if cannabis is used. Open windows and use fans. Keep pets out of the area until the air clears.
Avoid blowing smoke toward pets. It may seem obvious, but it happens. Dogs can be close to faces or laps.
Wash hands after handling oils or edibles. Oils can stick to skin. A dog that licks your hand may get a dose.

Build a “pet-safe routine” if cannabis is used often

Habits prevent mistakes. A routine makes safety automatic.

Set one storage spot and use it every time. Don’t leave products in random places like the couch, kitchen counter, or bedside table.
Do a quick “floor check.” Before letting your dog roam after use, scan for dropped gummies, crumbs, or joints.
Keep emergency numbers saved. Save your vet, the nearest emergency clinic, and a pet poison hotline in your phone.
Teach basic boundaries. Training like “leave it” can help, but it is not a guarantee. Storage is still the main protection.

Most THC exposures happen because a dog gets easy access. You can cut the risk a lot with a few strong habits: store cannabis locked up, keep edibles away from food areas, control bags and pockets when guests visit, secure the trash, avoid smoking or vaping near pets, and follow a consistent routine. If you do these things, you greatly reduce the chance that your dog will ever get “high” from weed.

Conclusion: Key takeaways and a simple action plan

If you think your dog may be high from weed, the most important thing is to stay calm and act quickly. THC (the main “high” chemical in cannabis) can affect dogs in ways that look scary, even when the problem can be treated. Your job is to notice the signs, keep your dog safe, and get the right help as soon as you can.

Start by watching for common signs that match THC exposure. Many dogs become wobbly, like they cannot walk straight. They may fall over, stumble, or seem weak in the legs. Some dogs look very sleepy and hard to wake up, while others act restless or confused. You may see drooling, vomiting, or a “glassy-eyed” look. Some dogs have accidents and drip urine without meaning to. These clues matter, because they help you and your veterinarian figure out what is happening. If you see severe signs like shaking that will not stop, seizures, collapse, trouble breathing, or your dog cannot stay awake at all, treat it as an emergency and go to an emergency clinic right away.

Timing also matters. How fast symptoms start depends on how your dog was exposed. If your dog inhaled smoke or vapor, signs may show up sooner. If your dog ate an edible, signs often take longer to appear, and the effects can get worse over the next hours. Edibles can also last longer than people expect. Some dogs improve within a day, but others can stay affected for one to three days. This does not always mean the situation is getting worse, but it does mean your dog may need careful watching, a quiet place to rest, and help from a veterinarian if signs are strong or not improving.

Safety at home is the next priority. A dog that is high may not be able to balance well, so accidents are common. Move your dog to a calm, safe space. Block stairs, keep them off furniture, and do not let them jump. Keep the room quiet and dim if your dog seems sensitive to noise or light. Stay close so you can prevent falls and check breathing and alertness. Offer small amounts of water only if your dog is awake and can swallow normally. Do not force food or water into the mouth of a sleepy or confused dog, because that can cause choking.

At the same time, gather information that will help a vet make good choices. If you can, find the package and read the label. Write down the THC amount per piece, like “10 mg per gummy,” and estimate how many pieces are missing. If it was flower or a vape oil, note the strength if it is listed. Try to remember when it happened or when you first noticed signs. Also note your dog’s weight, age, and any health problems or medicines. These details are useful because treatment depends on dose, time since exposure, and how your dog is acting right now.

Next, call for professional help. If your regular veterinarian is open, call them. If it is after hours, call an emergency clinic. In many areas there are animal poison hotlines that can guide you and work with your vet. Do not wait for signs to “wear off” if your dog is very sleepy, cannot walk, keeps vomiting, or you do not know how much they ate. Early advice can prevent problems, especially if the exposure was recent and your dog is still alert.

One of the biggest mistakes people make is trying to cause vomiting at home. This can be dangerous with THC exposure because many dogs become unsteady and sleepy. A dog that vomits while too sedated can breathe vomit into the lungs, which can lead to serious lung infection. Only a veterinarian should decide if vomiting is safe, and only when the timing and your dog’s condition make it a good idea. The same is true for activated charcoal or other treatments. These can help in some cases, but they must be used the right way and at the right time.

Knowing when to go in is key. Go right away if your dog has seizures, tremors that do not stop, trouble breathing, repeated vomiting, collapse, or cannot stand. Go urgently if your dog is very small, very young, very old, has heart or liver disease, or if the product was a concentrate like oil or wax. Also go urgently if the edible may include other toxins. Chocolate is common in baked edibles and can be toxic to dogs. Some candies and sugar-free products may contain xylitol, which can be very dangerous. Even if you are not sure, it is safer to contact a vet quickly and explain what your dog might have eaten.

If you do go to the vet, it helps to know what will happen. Most vets diagnose THC exposure based on history and a physical exam. Tests may be used to check blood sugar, hydration, and other body functions, but there is no single perfect test that proves cannabis exposure in every case. Treatment is usually supportive. That means the clinic helps your dog’s body stay safe while the drug wears off. Your dog may get fluids, medicine for nausea, temperature support, and close monitoring of heart rate, breathing, and alertness. Severe cases may need oxygen, help protecting the airway, or medicines to control seizures. Many dogs recover well with the right care.

Aftercare matters too. Once your dog is home, keep them quiet and supervised. Use a leash for potty breaks, because balance may still be poor. Keep them away from stairs and slippery floors. Watch for vomiting, weakness, or trouble staying awake. If signs return or worsen, call the vet again. Recovery can be slow, but steady improvement is a good sign.

Finally, prevention is the best long-term plan. Store cannabis products like you would store medicine: sealed, out of reach, and ideally locked. Do not leave edibles on counters or tables. Be careful with trash, wrappers, and leftovers after parties or guests. Remind visitors to keep bags and pockets closed and off the floor. If you smoke or vape, keep pets away from the area. A simple routine of safe storage and quick cleanup can prevent most cases.

In short, recognize the signs, act early, and focus on safety. Call a vet, do not try risky home treatments, and go to the clinic when signs are severe or the exposure is unknown. With fast action and proper care, many dogs make a full recovery.

Questions and Answers

Q1: What are the most common signs that a dog is “high” from weed?
Wobbly or uncoordinated walking, acting unusually sleepy or “spacey,” dribbling urine, vomiting, dilated pupils, tremors, and being extra sensitive to sound or light are common.

Q2: How soon after exposure would symptoms usually start?
Often within 30 minutes to a few hours, but edibles can take longer to kick in and can last longer than inhaled exposure.

Q3: What’s the difference between THC and CBD for dogs?
THC is the intoxicating part of cannabis and is the main cause of being high and toxicity. CBD is less likely to cause a high, but CBD products can still cause problems, especially if they are mislabeled or contain THC.

Q4: My dog seems anxious and restless—could that be weed?
It could be. Some dogs get agitated, vocal, or panicky instead of sleepy. Anxiety alone isn’t proof, but paired with wobbliness, urinary accidents, or unusual drowsiness, cannabis exposure is more likely.

Q5: What symptoms mean this is an emergency?
Go to an emergency vet now if you see repeated vomiting, seizures, severe tremors, extreme sleepiness or unresponsiveness, trouble breathing, very slow heart rate, collapse, or your dog can’t stay awake or stand.

Q6: Are edibles more dangerous than dried weed?
Often yes, because edibles can contain high THC plus extra toxic ingredients like chocolate, xylitol, raisins or grapes, or high-fat butter or oils, which can cause their own serious poisonings.

Q7: What should I do right away if I suspect my dog got into weed?
Remove access, keep them calm and in a safe, dim area, prevent falls, and call your vet or an emergency vet or an animal poison hotline with details: your dog’s weight, what was eaten or inhaled, how much you think, and when.

Q8: What should I NOT do at home?
Don’t try to wait it out without calling a professional if signs are moderate or severe. Don’t give human medications. Don’t force vomiting unless a vet specifically tells you to, because vomiting can be risky if your dog is sleepy or uncoordinated.

Q9: How do vets confirm it’s cannabis and what do they do?
Diagnosis is usually based on history and symptoms, and urine drug tests can be imperfect. Treatment is typically supportive care such as monitoring, fluids, anti-nausea meds, temperature control, and sometimes decontamination if it was recent and safe.

Q10: How long does a weed high or toxicity last in dogs, and will they recover?
Many dogs improve within 12 to 24 hours, but effects, especially from edibles, can last a day or more. Most recover fully with prompt care, but severe cases can be dangerous, so treat it as urgent until a vet advises otherwise.
