Dr. Ahna Brutlag as interview by NPR on marijuana poisoning in dogs. Click here to listen to the interview:
Dogs and cats can be poisoned by marijuana from second hand smoke exposure, or from direct ingestion of marijuana or baked foods (e.g., pot brownies, pot butter, etc.) laced with THC. In dogs and cats poisoned by marijuana, clinical signs can be seen within 3 hours, and include severe depression, walking as if drunk, lethargy, coma, low heart rate, low blood pressure, respiratory depression, dilated pupils, hyperactivity, vocalization and seizures. Vomiting is often seen with dogs despite the “anti-emetic” (anti-vomiting) qualities of THC.
The veterinary and toxicology experts at Pet Poison Helpline recommend that pet owners take immediate action if a pet is exposed to marijuana by contacting either their veterinarian or Pet Poison Helpline at 1-800-213-6680.
