Can dogs eat cannabis / marijuana / edibles?
If your dog has just eaten cannabis / marijuana / edibles
Do this now
- Call your vet or ASPCA (888) 426-4435 — BE HONEST about what was eaten
- Your vet/poison control is not reporting you — they need to know to treat your dog
- Identify the product: flower, edible (what kind?), concentrate, vape
- Check edibles for chocolate AND xylitol
- Estimate amount and time
- Do NOT induce vomiting without vet instruction — marijuana has anti-emetic effects that prevent vomiting anyway
- Watch for: wobbly walking, dilated pupils, urine dribbling, low body temp, slow heart rate, excessive sleeping or unresponsiveness, tremors
What your vet will want to know
Have this information ready when you call:
- Product type (flower, edible brand, oil, wax)
- Approximate THC content if known (percentage or mg)
- Other ingredients (chocolate, xylitol, butter)
- Amount eaten
- Time
- Your dog's weight
The full picture
Marijuana/THC ingestion in dogs has risen dramatically since US legalization — the ASPCA reports 300%+ increase in cannabis-related calls. Dogs are significantly more sensitive to THC than humans — they have more cannabinoid receptors in their brains, making symptoms more severe. Signs: wobbly walking (ataxia), dilated pupils, dribbling urine, hyperreactivity to sound/touch, low body temperature, slow heart rate, and in severe cases collapse, coma, or seizures. The combination with edibles makes things worse: brownies add chocolate toxicity, gummies often contain xylitol (emergency), baked goods add butter/sugar (pancreatitis). Important — be honest with your vet. They aren't legally reporting you; they need accurate info to treat your dog. Symptoms typically last 12-24 hours, but can be 48+ hours with high-THC edibles. Supportive care is usually sufficient but hospitalization may be needed.
If your dog ate chocolate, enter their weight and how much they ate for an instant risk assessment based on theobromine levels.

Check if vomiting is safe →Risks to watch for
- Neurological: ataxia, tremors, seizures
- Cardiovascular: slow heart rate, low blood pressure
- Respiratory depression at high doses
- Hypothermia (low body temp)
- Coma at very high doses
- COMBINED risks: chocolate (edibles), xylitol (gummies), butter (pancreatitis)
Symptom timeline
Symptoms typically progress in stages. Knowing what to expect helps you act fast:
- 30 min - 2 hours Onset: ataxia, dilated pupils, subtle behavioral changes
- 2–6 hours Peak: profound wobbliness, urinary dribbling, slow heart rate, low temperature
- 6–24 hours Gradual resolution with supportive care
- 24–48 hours Full resolution typical; high-THC edibles may extend effect
Breed-specific warnings
- Small dogs severely affected by doses that barely affect large dogs.
- Senior dogs and those on cardiac medications at higher risk.
- Brachycephalic breeds at elevated aspiration risk if vomiting.
Safe portion size
None. Note: prescription veterinary cannabinoid medications may be used in specific cases under specialist care — but that's different from human marijuana.
Safer alternatives
- Veterinary cannabinoid products under specialist care only
- Prescription anxiety/pain medications appropriate to the condition
Common questions
Is my dog going to die from eating marijuana?
Usually no — even severe cases typically recover with supportive care. The exception is when the edible contained other toxins (chocolate brownies, xylitol gummies) or when a very small dog ate very high-THC concentrates. Still always a vet call.
Why does my vet need to know it was marijuana specifically?
To differentiate from other neurological toxins (some require very different treatment), to gauge recovery timeline, and to monitor for specific side effects. Accurate info = better care. They're not going to report you.
What if it was an edible with chocolate?
Multiple toxicity — treat as both chocolate AND THC emergency. Use our chocolate toxicity calculator for that dose, and call your vet specifically mentioning both.
My dog ate a THC gummy — is that worse?
Potentially yes, because THC gummies OFTEN contain xylitol — which is a separate, serious emergency. Check the gummy's ingredients immediately. Xylitol can cause hypoglycemia within 30 minutes.
