Mon chien a mangé de la marijuana/comestibles : Que faire maintenant
Les chiens sont plus sensibles au THC que les humains. Les comestibles (bonbons, brownies) sont particulièrement dangereux en raison de leur concentration élevée.
📋 Important : Soyez honnête avec votre vétérinaire

Que faire maintenant
- 1
Step 1: Remove All Remaining Product
Check for packaging — note THC content in mg per piece and total pieces eaten. This determines toxicity risk.
- 2
Step 2: Check for Xylitol (CBD Products)
⚠️ Some CBD oils contain xylitol, which is extremely toxic to dogs. Check the ingredient list immediately.

Step 4: Monitor Symptoms
Watch for: stumbling, dilated pupils, urinary incontinence, drooling, slow heart rate, hypothermia. Severe cases: seizures or coma. Symptoms can last 12-72 hours.
La science derrière
Le Delta-9-tétrahydrocannabinol (THC) se lie aux récepteurs cannabinoïdes CB1 dans le système nerveux central canin. Les chiens ont une densité plus élevée de récepteurs CB1 dans le cervelet (responsable de la coordination) et le tronc cérébral que les humains, ce qui explique leur sensibilité accrue. Le THC est lipophile et subit une recirculation entéropatique, prolongeant les effets. Les edibles sont dangereux car le tractus gastro-intestinal absorbe rapidement le THC, et le foie convertit le 11-hydroxy-THC, qui est 5 fois plus psychoactif. La plupart des cas sont traités de manière supportive — il n'y a pas d'antidote spécifique, mais la thérapie par émulsion lipidique IV peut accélérer l'élimination du THC (ASPCA, 2023).
Questions fréquentes
Is marijuana toxic to dogs?
Yes, THC (tetrahydrocannabinol) is toxic to dogs. Dogs have more cannabinoid receptors (CB1) in the brain than humans, making them significantly more sensitive. Edibles (gummies, brownies, cookies) are especially dangerous due to high THC concentration — one gummy can contain 10-100mg THC, which is toxic to most dogs.
What are the symptoms of marijuana poisoning in dogs?
Symptoms appear within 30-90 minutes: dazed appearance, stumbling/ataxia, urinary incontinence (dripping urine), drooling, dilated pupils, vomiting, tremors, bradycardia (slow heart rate), hypothermia, and in severe cases: seizures or coma. Be honest with your vet — marijuana toxicosis is rarely fatal, and honesty ensures proper treatment.
Are marijuana edibles more dangerous than dried cannabis?
Yes, edibles are significantly more dangerous: (1) High THC concentration (10-100mg per piece), (2) Often contain chocolate (double toxicity), (3) Faster absorption from GI tract, (4) Dogs eat multiple pieces quickly. Edibles account for the majority of severe cannabis toxicosis cases in dogs.
Can a dog die from eating marijuana?
Fatalities from marijuana alone are rare in dogs — the LD50 is very high (over 3g/kg of THC). However, edibles pose additional risks: chocolate toxicity, xylitol in some CBD products, and overdose from multiple ingestion. Death is more likely from complications (aspiration pneumonia, hypothermia) or combined toxins. Always seek veterinary care.
Should I tell my vet my dog ate marijuana?
Yes, always be honest. Veterinarians are required to treat, not report, pet poisonings. Knowing your dog ate marijuana ensures they provide appropriate care: inducing vomiting (if early), activated charcoal, IV fluids, thermoregulation, and monitoring heart rate. Without this information, your dog may undergo unnecessary tests or receive inappropriate treatment.
