My 40 pound 2 year old border collie ate 0-3 cigarettes, what should I do? It was 15 minutes ago and he currently isn't exhibiting any symptoms of nicotine toxicity.

Hello, I recommend that your dog is seen by a veterinarian to induce vomiting. If you cannot reach a veterinarian soon, I would administer 2 tablespoons of hydrogen peroxide by mouth to induce vomiting while you make your way to the ER. Nicotine can cause abnormal heart rhythms and the toxicity depends on how much nicotine is in each cigarette. Hope this helps.

    Bruce should be taken to the nearest veterinary ER. One cigarette can cause toxicity in a 40lb dog. Vomiting can be induced via injection to get the cigarettes out. Activated charcoal can be given afterwards to further reduce nicotine absorption. He may need to be monitored overnight to watch for vomiting, rapid heart rate, abnormal heart rate or even seizures. Do not delay. Treatment is most successful if administered within 2 hours of ingestion.
