Dog Ate Weed or Marijuana?
THC is toxic to dogs. Marijuana edibles are especially dangerous because they often contain both THC and chocolate or xylitol. Get veterinary help quickly.
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.

- 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
