Treatment for pet ingestion of cannabis starts with a phone call, not a home remedy. Contact a veterinarian or animal poison control immediately, then follow their direction on decontamination. Clinical care typically combines induced vomiting (only when a vet instructs it), activated charcoal when appropriate, intravenous fluids, anti-nausea medication, and monitoring of heart rate, body temperature, and neurologic status. Most pets recover within 12 to 24 hours, but high-dose THC edibles can cause severe or fatal poisoning.
Symptoms of Cannabis Ingestion in Pets: What to Watch For
What should I do first if my pet ate cannabis?
Call a veterinarian, an emergency clinic, or a poison hotline before symptoms appear. Have the product packaging ready so you can state the THC content, the amount eaten, and the time of ingestion.

Do not wait for your pet to look sick. Signs can take 30 to 90 minutes to appear after smoking or vaping exposure, and up to 12 hours after an edible.
First Aid for Pet Cannabis Ingestion: What to Do First
- Keep the container, wrapper, or label for the vet.
- Note your pet's weight and any other foods eaten, especially chocolate or xylitol gum.
- Do not induce vomiting, give food, or offer activated charcoal unless a veterinarian tells you to.
What are the signs of cannabis poisoning in pets?
Dogs are far more sensitive to THC than humans because they have a higher density of cannabinoid receptors in the brain. Common signs include lethargy, wobbling, dilated pupils, drooling, vomiting, urinary incontinence, and sensitivity to sound or touch.

Severe cases involve tremors, slow heart rate, low body temperature, seizures, coma, or respiratory depression. Cats show similar neurologic signs but often with more agitation and hiding.
How do veterinarians treat cannabis ingestion?
- Decontamination: vomiting is induced within one to two hours of ingestion in stable patients, never in pets that are already sedated or seizing.
- Activated charcoal: given by a vet to bind remaining toxin, and skipped if the pet is vomiting or has an ileus.
- Supportive care: IV fluids, antiemetics, thermal support for low body temperature, and blood glucose checks.
- Advanced care: lipid emulsion therapy, anticonvulsants, oxygen, or mechanical ventilation for the most severe cases.
- Monitoring: hospitalized observation for 12 to 24 hours, longer if the pet ate a concentrated edible.
Is CBD different from THC for pets?
Yes. THC is the intoxicating compound responsible for most pet poisonings, while CBD products made for animals usually contain little or no THC. Many human CBD oils, gummies, and vape cartridges contain THC, and those are the products pets most often get into.
Even hemp-derived CBD can cause stomach upset, sedation, or changes in liver enzyme levels in pets. Keep every cannabis product, including edibles, in a locked or high cabinet.
When is cannabis ingestion fatal?
Deaths are uncommon and are linked to very large THC doses, concentrated edibles, or co-ingestion of chocolate, raisins, or xylitol. Pets with heart disease, seizures, or a small body weight face a higher risk.
A veterinary exam, not at-home watching, is what separates a mild case from a life-threatening one.
