You found the shredded packaging, and your stomach dropped.
First: it's not your fault (these things happen), and most dogs recover fully. Second, and more important, this is a real emergency that a professional should weigh in on right now, not in an hour.
If a dog eats THC gummies, the THC is absorbed and can cause cannabis poisoning, because dogs are far more sensitive to it than people.
Signs include a wobbly, drunken walk, dribbling urine, lethargy, dilated pupils, drooling, and sometimes vomiting or tremors, usually starting within 30 to 60 minutes.
Call your veterinarian or an animal poison control line immediately, whatever the dose, and do not induce vomiting on your own.
Most dogs recover with supportive care, but edibles can also contain xylitol or chocolate, which are separate, potentially deadly dangers.
Call for help right now
Contact your vet or a 24/7 animal poison control line before anything else. Have the packaging handy so you can report how much THC and which other ingredients were involved.

Quick Takeaways
- Call your vet or animal poison control immediately, no matter how much your dog ate.
- Signs start in 30 to 60 minutes: wobbly gait, urine dribbling, lethargy, dilated pupils.
- Do not induce vomiting unless a vet tells you to.
- Xylitol and chocolate in some edibles are separate, potentially fatal dangers.
- Most dogs recover fully with supportive care, usually within a day or two.
Why Is THC Toxic to Dogs?
Dogs have far more cannabinoid receptors in their brains than humans, so a dose that would barely affect a person can hit a dog hard.
Dogs have an endocannabinoid system like ours, but with a much higher concentration of CB1 receptors in the brain.
That makes them dramatically more sensitive to THC, which is why an amount that's mild for an adult can cause real poisoning in a dog.
Per the Merck Veterinary Manual, edible products are especially risky because they can be high in THC and may contain other toxic ingredients.
Signs of THC Poisoning in Dogs
The hallmark combination is a wobbly walk plus dribbling urine, often with a dazed, sedated look. Signs usually appear within 30 to 60 minutes.
Common signs
- Wobbly, uncoordinated "drunken" walk (ataxia)
- Leaking or dribbling urine
- Lethargy, sedation, or disorientation
- Dilated pupils and glassy eyes
- Drooling, and sometimes vomiting
- Startling at sounds or touch
More serious signs
- Tremors or shaking
- A slow heart rate
- Low body temperature
- Agitation or restlessness
- Seizures (in severe cases)
- Unresponsiveness or collapse
The American Kennel Club notes that urinary incontinence and an unsteady gait are classic tells of marijuana poisoning in dogs. If you see any of the more serious signs, get to a clinic right away rather than waiting it out.
The bigger danger: xylitol and chocolate
THC alone is rarely fatal to a dog, but many gummies and edibles contain ingredients that can be. Xylitol, a sweetener in many sugar-free gummies, is extremely toxic to dogs.
The FDA warns it can cause a rapid, dangerous drop in blood sugar and liver failure. Chocolate and raisins in some edibles are toxic too.
This is why the ingredient list matters as much as the THC. Read the package, and tell the vet exactly what was in it, including the sweetener.
What to Do if Your Dog Ate THC Gummies
Act fast, call a professional, and don't try to treat it yourself.
- Call your vet or animal poison control now. Use the numbers above. Do this even if your dog seems fine, because signs can take up to an hour to appear.
- Grab the packaging and estimate the amount. Note the THC per piece, how many are missing, and every other ingredient, especially xylitol or chocolate. This determines the treatment.
- Do not induce vomiting on your own. It can do more harm than good and should only be done under veterinary direction.
- Be completely upfront. Vets and poison lines exist to help your pet, not to report you. Hiding what happened only slows down care.
- Keep your dog calm, warm, and supervised. Reduce noise and light, and follow the instructions you're given, whether that's monitoring at home or coming in.
What the Vet Will Do
There's no antidote for THC, so care is about supporting your dog while their body clears it.
Depending on the dose and timing, a vet may give anti-nausea medication, IV fluids, and help regulate body temperature, and monitor your dog until the effects pass.
If the gummy was eaten very recently, they may induce vomiting or give activated charcoal to limit absorption. Severe cases are managed in the hospital.
Most dogs are back to normal within about 24 hours, though it can take a couple of days depending on the amount.
How to Prevent It Happening Again
If your dog found the stash once, they'll look for it again. Store THC like medication, high, sealed, and locked.
Store it safely
- Keep gummies in high cabinets, out of reach
- Use child-proof, sealed containers
- A locked drawer or box for real peace of mind
- Never leave edibles on counters or nightstands
Get everyone on board
- Tell roommates, partners, and kids what happened
- Agree on where THC products live
- Keep bags and pockets with edibles zipped away
- Check the floor after guests visit
If your dog needs calming, use a pet-safe option
Human THC and CBD edibles are never for dogs. If your pup struggles with anxiety, choose a product made for dogs, like Calming Treats for Dogs, which are THC-free and use CBD isolate.
They're for everyday calm, not for treating poisoning, so any suspected THC ingestion still needs a vet.
What Happens if a Dog Eats THC Gummies: The Bottom Line
Call for help immediately, and take a breath: most dogs recover fully.
THC is toxic to dogs, and while it's rarely fatal on its own, the wobbliness, urine dribbling, and sedation are deeply distressing, and hidden ingredients like xylitol or chocolate can be deadly.
Call your vet or an animal poison control line right away; don't induce vomiting on your own, bring the packaging, and be upfront about what and how much your dog ate.
Then store your THC products locked and out of reach, so it never happens again.
Frequently Asked Questions
Can a dog die from eating THC gummies?
Death from THC alone is rare, but possible with very high doses. The greater risk is other ingredients: xylitol and chocolate in some edibles can be fatal to dogs. Any suspected ingestion should be treated as an emergency and reviewed by a vet.
How much THC is toxic to a dog?
There's no safe amount, and dogs are far more sensitive than people, so even a small dose can cause poisoning, especially in a small dog. Don't try to judge whether it's "enough" to matter. Call a vet or poison control and let them assess it.
How long until my dog recovers?
Most dogs return to normal within about 24 hours, though it can take a day or two depending on the dose and treatment. Your vet will guide monitoring. Effects typically start within an hour of eating the gummies.
Should I make my dog throw up?
Not on your own. Inducing vomiting can cause complications and should only be done under veterinary direction. Call your vet or an animal poison control line first and follow their instructions.
My dog seems fine. Do I still need to call?
Yes. Signs can take up to an hour to appear, and you can't see how much was absorbed. Calling early gives your dog the best outcome, even if they look okay right now.
Will I get in trouble for telling the vet?
No. Vets and poison control lines are focused on treating your pet, not reporting you. Being fully upfront about what your dog ate, including the amount and other ingredients, is the single most helpful thing you can do.
These statements have not been evaluated by the Food and Drug Administration. This article is general information, not veterinary advice, and is not a substitute for professional care. If you suspect your dog has eaten THC or any toxic substance, contact your veterinarian or an animal poison control line immediately. Never give human THC or CBD products to pets, and keep all THC products securely stored away from children and animals.
