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

O Que Fazer Agora
- 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.
A Ciência Por Trás Disso
Nicotina é um alcaloide que se liga aos receptores nicotínicos de acetilcolina (nAChRs) nos gânglios autônomos, junções neuromusculares e SNC. Em doses baixas, estimula receptores causando taquicardia, hipertensão e excitação do SNC. Em doses altas, causa bloqueio de despolarização do receptor, levando à bradicardia, paralisia respiratória e coma. O efeito bifásico (estimulação seguida de depressão) é patognomônico. Cães metabolizam nicotina primariamente via N-oxidação hepática, com uma meia-vida de aproximadamente 1,5 horas. Líquido de vape representa perigo extremo porque 1mL pode conter 3-24mg de nicotina absorvida rapidamente através da mucosa oral (ASPCA, 2023).
Perguntas Frequentes
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.
