今すぐやるべきこと
- 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.
その背後の科学
デルテトラヒドロカンナビノール（THC）は犬の中枢神経系のCB1カンナビノイド受容体に結合します。犬は人間よりも小脳（協調性に関脳）と脳幹のCB1受容体密度が高く、その高い感受性を説明しています。THCは親油性で肝腸循環を起こし、効果を延長します。エディブルは危険です。GI管がTHCを迅速に吸収し、肝臓が11-ヒドロキシ-THCに変換します。これは5倍精神活性が強いです。ほとんどの病例は支持的です—特異的な解毒剤はありませんが、IV脂質エマルジョンテラピーはTHCクリアランスを加速できます（ASPCA、2023）。
よくある質問
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.
