If your pet eats cannabis, call a veterinarian or an animal poison control hotline right away. Most pets survive THC exposure with supportive care, but the first two hours matter for decontamination. Do not wait for symptoms before you make the call.
first aid for pet cannabis ingestion
Pet ingestion of cannabis treatment follows a set path: remove what is left in the stomach, support the body, and watch until signs clear. The exact steps depend on the pet's weight, the product, and how long ago the dose went in.

What should you do first after a pet eats cannabis?
Calling for guidance beats guessing. Poison control staff will ask about the pet's weight, the product, and the amount eaten, then tell you whether to head to a clinic. Your own vet is often the fastest first call.
what to do if my pet ate cannabis
- Note the product name, its THC and CBD content, and the package weight.
- Save the wrapper or container and any leftover material.
- Write down the time of ingestion and the pet's weight in pounds.
- Keep the pet warm and calm while you call. Do not let them stumble down stairs.
Pets who ate edibles face a second problem. Chocolate, xylitol, raisins, and macadamia nuts in the same treat carry their own toxicity.

Why does cannabis hit dogs and cats harder than people?
Dogs have a higher density of CB1 receptors in the brain than humans do. That makes them more sensitive to THC, the compound behind most poisoning cases. Cats get exposed less often, but they react in similar ways.
THC vs CBD risk
CBD alone has a wide safety margin in pets, and reported side effects are mild. THC is the compound that causes wobbling, urine dribbling, and tremors. A full-spectrum product with high THC content can sicken a small dog from one dose.
What are the signs of cannabis poisoning in a pet?
Signs start 30 to 60 minutes after ingestion and can last 12 to 24 hours. Edibles take longer to hit and often last past 24 hours because the body absorbs them over hours instead of minutes.
- Drowsiness, staring, or a dazed look
- Wobbling, crossing the legs, trouble standing (ataxia)
- Dribbling urine without control
- Dilated pupils and slow response to light
- Vomiting, drooling, or low appetite
- Slow heart rate and low body temperature
- Tremors, agitation, or head twitching at high doses
- Coma or seizures in severe cases
Most pets are awake but "not right." A dog who drips urine and sways when standing is the classic picture. Vets often spot it before an owner mentions the edible.
How much THC is dangerous for a pet?
There is no clear threshold, and reactions vary by weight, product, and body fat. Severe signs appear with large doses of THC, and deaths from cannabis alone are rare. Fatal reports often involve another toxin taken at the same time.
How do vets treat cannabis ingestion in pets?
Treatment is supportive and depends on how much time has passed. There is no antidote that reverses THC, so care focuses on removing the drug and keeping the pet stable.
- Decontamination. If the pet ate within one to two hours and can stand steady, the vet may induce vomiting. Activated charcoal can bind what is left in the stomach.
- Fluids and warmth. IV fluids support blood pressure and speed drug clearance. Warming blankets help pets with low body temperature.
- Symptom control. Anti-nausea drugs, anti-anxiety drugs, and in severe cases medications for tremors or seizures.
- Monitoring. Vets track heart rate, temperature, and blood glucose until signs fade.
- Lipid emulsion in severe cases. An IV fat emulsion pulls THC out of tissue, and vets use it for pets with profound signs.
Most pets go home within 24 to 72 hours. A large edible dose can keep a pet in the clinic for longer.
What should you not do?
Home remedies cause more harm than the cannabis in many cases. Wait for a vet to guide you.
- Do not induce vomiting on your own. Hydrogen peroxide burns the stomach, and a wobbly pet can inhale vomit into the lungs.
- Do not give activated charcoal at home. It can cause choking, and it does nothing for dehydration.
- Do not give more CBD, coffee, or human medications to "wake them up."
- Do not leave the pet alone to sleep it off. Tremors and low body temperature need care.
Does pet CBD carry the same risk?
Trace THC in a full-spectrum pet oil sits far below the dose that causes poisoning in most cases. The bigger risk comes from human edibles and vape leftovers that pets find on the floor or in bags. Check the certificate of analysis for THC content before you buy any pet product.
How can you prevent pet ingestion?
- Store edibles and flower in a locked box, not a zipper bag. Dogs chew through plastic and childproof lids.
- Sweep floors for roaches, vape carts, and dropped gummies.
- Keep purses and backpacks off the floor after a night out.
- Post the poison control numbers where the whole household can see them.
Frequently asked questions
How long does cannabis stay in a pet's system?
Behavior signs fade in 12 to 24 hours for smoked or raw material. Edibles can keep a pet wobbly for up to 36 hours. Full clearance takes a few days, and urine tests can pick up traces for weeks after heavy exposure.
Can a dog die from eating weed?
Deaths from THC alone are rare in veterinary reports. Fatal cases often involve a huge dose, a very small pet, or another toxin such as chocolate or xylitol. Call for help either way.
Should I give my pet CBD after they eat THC?
No. CBD does not reverse THC, and it adds to the load the liver has to process. Let the vet decide what the pet needs.
Can pets get high from secondhand smoke?
Yes, though signs are mild in most cases. A small pet in a closed room with heavy smoke can show drowsiness and wobbling. Smoke also irritates the airways, so keep pets out of the room.
When should you call for help?
Call at once if a pet ate any cannabis product, whatever the size. Two US hotlines run 24 hours: ASPCA Animal Poison Control at (888) 426-4435 and Pet Poison Helpline at (855) 764-7661. Both charge a consultation fee per case.
