Dog ate marijuana / THC
If your dog has eaten marijuana, an edible, or a THC oil, call a veterinarian or animal poison control line now — dogs are far more sensitive to THC than people. Typical signs include wobbliness, a dazed or glassy look, dribbling urine, sensitivity to sound or touch, a slow heart rate, and sometimes tremors. Edibles are extra dangerous because they can also contain chocolate, xylitol, or raisins. Be completely honest with your vet about what and how much — they are there to help your dog, not to judge you, and accurate information leads to the right treatment.
Go to a vet now if
- Marked wobbliness, dazed/glassy eyes, or collapse
- Dribbling urine, tremors, or twitching
- An edible that may also contain chocolate, xylitol, or raisins
- A small dog, a puppy, or a large amount eaten
Call a vet today if
- Mild, brief drowsiness in a large dog after a tiny exposure (still call your vet for advice)
What to tell the vet
- What form (bud, edible, oil) and how much
- When it happened
- Whether the product also contained chocolate, xylitol, or raisins
- Your dog's weight
- Signs so far
- Any other medicines or conditions
What not to do
- Do not wait out of embarrassment — honesty helps your vet treat your dog correctly
- Do not make your dog vomit unless a vet directs you to
- Do not give food, milk, or home remedies to 'flush it out'
What your vet may check
Your vet will assess how affected your dog is, support breathing, temperature and hydration, and monitor the heart. Most dogs recover with supportive care, though concentrated edibles and oils can cause more serious effects.
Recovery support after veterinary assessment
Most dogs recover fully with monitoring. Your vet will advise when to reintroduce food and water; any supportive nutrition during recovery is used on veterinary advice.
Frequently asked questions
Is marijuana dangerous for dogs?
Yes. Dogs are much more sensitive to THC than humans, and signs like wobbliness, dribbling urine, and tremors can be marked. Concentrated edibles and oils are especially risky.
Should I tell the vet my dog ate cannabis?
Absolutely. Vets are there to help your dog, not to report you. Honest information about the type and amount lets them treat your dog quickly and correctly.
Why are cannabis edibles extra dangerous for dogs?
Edibles can combine THC with chocolate, xylitol, or raisins — each toxic to dogs on its own — so the risk is higher than cannabis alone. Tell your vet exactly what was in it.
