|---|---|---|---|
| E-liquid (any amount) | Even a few drops | CRITICAL | 🚨 Emergency vet NOW — highly concentrated |

今すぐやるべきこと
- 1
Step 1: Calculate Total Nicotine
Count cigarettes/packages consumed. Cigarette: 10-15mg each. E-liquid: check mg/mL concentration × mL consumed. This determines toxicity risk.

Step 2: Call Poison Control IMMEDIATELY
📞 <strong>ASPCA Poison Control:</strong> (888) 426-4435. Nicotine is absorbed rapidly through oral mucosa — effects can begin within 15 minutes.

Step 3: Do NOT Induce Vomiting If Symptomatic
⚠️ If your dog shows tremors, seizures, or agitation, inducing vomiting risks aspiration. Only induce if instructed by a professional AND your dog is asymptomatic within 15 minutes.

Step 4: Go to Emergency Vet for Monitoring
Your vet will administer activated charcoal, provide IV fluids, and monitor heart rhythm and respiratory function. Symptoms can progress rapidly.
その背後の科学
ニコチンはアルカロイドで、自律神経節、神経筋接合部、CNSのニコチン性アセチルコリン受容体（nAChR）に結合します。低用量では受容体を刺激し、頻脈、高血圧、CNS興奮を引き起こします。高用量では受容体脱分極遮動を引き起こし、徐脈、呼吸麻痺、昏睡につながります。二相性効果（刺激然後抑制）は特徴的です。犬は主に肝N-酸化を通じてニコチンを代謝し、半減期は約1.5時間です。電子液体は1mLに3-24mgのニコチンを含む可能性があり、口腔粘膜から迅速に吸収されるため極めて危険です（ASPCA、2023）。
よくある質問
How much nicotine is toxic to dogs?
The toxic dose of nicotine in dogs is 20-100mg/kg. For a 20kg dog, this equals 400-2000mg of nicotine. Sources: 1 cigarette = 10-15mg nicotine, 1 cigarette butt = 5-7mg, nicotine patch = 8-21mg, nicotine gum = 2-4mg, e-liquid = 3-24mg/mL (highly concentrated). Even ONE cigarette can cause symptoms in a small dog.
What are the symptoms of nicotine poisoning in dogs?
Symptoms appear within 15-60 minutes: hypersalivation, vomiting, tachycardia (rapid heart rate), muscle tremors, agitation, and hypertension. As toxicity progresses: bradycardia (slow heart rate), weakness, collapse, respiratory paralysis, and seizures. The biphasic effect — first excitation then depression — is characteristic of nicotine poisoning.
Is vape liquid dangerous for dogs?
Yes, e-liquid (vape juice) is EXTREMELY dangerous due to high nicotine concentration. A single 10mL bottle can contain 30-240mg of nicotine — enough to kill multiple small dogs. The sweet flavorings also attract dogs. Ingestion of even small amounts requires emergency veterinary treatment.
What should I do if my dog ate tobacco?
Call ASPCA Poison Control at (888) 426-4435 immediately. Calculate total nicotine consumed: mg per item × number of items. Go to emergency vet if your dog ingested: (1) more than 1 cigarette, (2) any e-liquid, (3) a nicotine patch, or (4) any amount if your dog shows symptoms. Do NOT induce vomiting if seizures or tremors are present.
