THC is toxic to dogs — edibles are especially dangerous
Dogs are much more sensitive to THC than humans. Marijuana toxicity in dogs has increased dramatically with the rise of high-potency edibles. Edibles are doubly dangerous because they may also contain chocolate, xylitol (artificial sweetener), or butter — all harmful to dogs.

What to Do Right Now
Be honest with your vet — they're there to help your dog, not to judge. Accurate information saves time and lives.
- Call your vet or emergency clinic immediately
- Tell the vet exactly what your dog ate — the form, amount, and when
- If it was an edible, check the label for chocolate, xylitol, or other toxic ingredients
- Do NOT induce vomiting unless specifically directed by the vet
- Keep your dog in a quiet, safe space — they may be disoriented and frightened
Symptoms from edibles can appear within 30-90 minutes of ingestion
THC effects in dogs typically last 12-24 hours with supportive care
Marijuana toxicity cases in dogs have surged with edible legalization
