Dogs have significantly higher concentrations of CB1 receptors in the brain than humans, making THC ingestion uniquely toxic and distressing. Dr. Benjamin Caplan explains what happens when dogs consume cannabis and what steps owners must take.
Can Dogs Get High? The Science of Canine Cannabis Toxicity
If your dog consumed an edible, they aren’t ‘vibing’—they are experiencing acute toxicosis. Dr. Caplan explains why dogs are hypersensitive to THC and what veterinary steps to take immediately.

This neuroanatomical difference means dogs experience severe neurological ataxia, hypothermia, and extreme distress from THC quantities that a human might barely notice. Furthermore, edibles often contain toxic ingredients like chocolate, xylitol, or raisins, creating a compounding medical emergency.
- Static Ataxia: Wobbly, uncoordinated gait and swaying stance.
- Urinary Incontinence: Leaking urine (seen in over 50% of canine toxicity cases).
- Hypothermia & Bradycardia: Abnormally low body temperature and slow heart rate.
- Hyperesthesia: Extreme flinching or startling in response to mild light or sound.
Frequently Asked Questions
Can weed kill a dog?
While fatal THC overdoses are rare, severe toxicity can lead to dangerous hypothermia, respiratory depression, seizures, and death—especially if combined with chocolate, xylitol, or high-potency concentrates.
What should I do if my dog ate an edible?
Contact an emergency veterinary hospital or animal poison control immediately. Bring the product packaging so veterinarians can calculate the exact milligrams of THC and check for other toxic additives.
How long does weed toxicity last in dogs?
Symptoms typically manifest within 30 to 90 minutes and can persist for 12 to 36 hours due to prolonged canine metabolic clearance.
