Nicotine & Tobacco

Ingestion of nicotine may be toxic to your pet. It can be found in many products including:

    • chewing tobacco
    • cigarettes
    • cigars
    • bidis
    • traditional nicotine replacement therapies (e.g., patches, gum)
    • newer replacement therapies (e.g., electronic cigarettes, nasal sprays, inhalers)


Some nicotine products may be flavored, increasing the appeal to your pet. Note that nicotine gums may also contain xylitol, also considered a toxin to dogs.

Ingestion of cigarette butts may also cause toxicity. Do not leave ashtrays or nicotine containing products within your pets reach.

Birds are also indicated for this toxicity, particularly with inhalation of second hand tobacco smoke.

Signs and symptoms of toxicity: Vomiting is common following ingestion. Other signs of toxicity include increased saliva production, diarrhea, increased activity and agitation followed by extreme depression, difficulty walking, seizures, tremors, and increased heart rate. Clinical signs often develop within 1 hour of ingestion.

Toxic consumption: In dogs, a dose of 9-12 mg/kg is considered lethal. There is no established toxic threshold for cats. All incidents of accidental exposure should be reported immediately.

Pets often vomit immediately following ingestion, making severe clinical toxicosis less likely to occur.
