Cannabis ingestion in pets: the short answer
A pet who has eaten cannabis usually looks drunk. The first signs tend to show up 30 to 60 minutes after a dog or cat eats plant material, and 1 to 2 hours or longer after an edible. The classic cluster is lethargy, dilated pupils, a wobbly wide-stance walk, vomiting, and urine leaking while the pet lies still. Most pets recover with supportive care, but some need IV fluids and a hospital stay, and a few serious cases involve tremors, seizures, or slowed breathing.
pet ingestion of cannabis treatment
If you see that combination and there is any chance cannabis was in reach, call your veterinarian or a pet poison hotline right away. Do not wait for the pet to "sleep it off."
Common symptoms
- Wobbling, swaying, or staggering, often called ataxia
- Drowsiness that is out of character, or a pet who will not stand
- Dilated pupils that react poorly to light
- Vomiting, retching, and drooling
- Urinary incontinence, meaning the pet urinates while lying down or without getting up
- Low body temperature and a slow heart rate
- Twitching, startle responses, or sensitivity to touch
- Rapid eye flicking, known as nystagmus
- Head tilting, head pressing, or a blank stare
- Unusual vocalization, agitation, or the opposite, a flat unresponsive state
Dogs are far more likely than cats to eat cannabis. Cats tend to get into it less often, but they are more prone to hiding when something feels wrong, so a quiet cat under the bed with wide pupils is worth a close look.

Symptoms that mean go now
Some signs point to a pet who needs emergency care instead of a wait-and-watch approach:
What to Do If My Pet Ate Cannabis
- Seizures or continuous trembling
- Slow, shallow, or labored breathing
- Pale, white, or blue-tinged gums
- Heart rate that is very fast, very slow, or irregular
- Unresponsiveness or a pet you cannot rouse
- Repeated vomiting that will not stop
- Body temperature that feels cold to the touch
Chocolate, raisins, and xylitol are the other reason to move fast. THC and a second toxin in the same bite change the whole picture.
Why edibles are often worse than flower
A baked good with cannabis in it can carry a concentrated dose of THC along with chocolate, sugar, raisins, or xylitol. Chocolate adds theobromine and caffeine, which push heart rate and can cause tremors on their own. Xylitol drops blood sugar and can damage the liver. Raisins can trigger kidney injury.
Dose matters too. THC affects a 12-pound terrier very differently than an 80-pound shepherd, and an edible made for a person may hold several times the amount that causes heavy sedation in a small dog. Onset is also slower with edibles because the pet has to digest the food first, so symptoms can appear hours after you last looked at the pet and think everything is fine.
What to do in the first hour
- Call your vet, an emergency clinic, or a pet poison hotline before you do anything else. They will tell you whether this is a watch-at-home situation or a come-in-now situation.
- Move your pet away from the source and pick up whatever is left, including wrappers, so you can describe it.
- Do not induce vomiting unless a veterinarian tells you to. It can be dangerous with some products and with certain pets.
- Write down the time you think the pet ate it, how much, and what the product was. THC content on the label helps, but bring the package anyway.
- Keep the pet warm, quiet, and on the floor or a low bed so a fall cannot happen. Carry small pets instead of letting them walk stairs.
- Do not give food, coffee, oil, or any home remedy to "sober them up." None of that works and some of it causes more harm.
How vets confirm it and treat it
There is no antidote for cannabis. A veterinarian may run a urine drug screen that detects the THC metabolite, plus blood work to check glucose, liver, and kidney values and rule out other causes that mimic the signs. If the pet was seen within a short window, the vet may give activated charcoal to limit absorption. From there it is supportive care: IV fluids, anti-nausea medication, warmth, oxygen if breathing is depressed, and monitoring. Most pets improve within 12 to 24 hours, though edibles can stretch the timeline to 72 hours in heavy cases. Deaths are uncommon, but they do happen, usually with a large dose, a small pet, or a second toxin in the mix.
Keeping it out of reach
- Store edibles in a locked drawer or cabinet, not a purse, backpack, or nightstand.
- Keep joints, roaches, vape cartridges, and used flower material off coffee tables and floors. Dogs happily eat stems and ash.
- Watch the floor at gatherings. A dropped gummy is gone in a second.
- Tell your vet the truth about what your pet got into. It changes treatment and it is not a police report.
A word about CBD products for pets
CBD is not THC, and a hemp product is not the same as a marijuana edible. That said, CBD products for animals are not FDA approved, and independent testing has found that some labels do not match what is in the bottle, including THC content. Never give your pet a product made for people. If you are considering CBD for a pet, talk to your veterinarian first and choose a brand that publishes third-party lab results for every batch.
