What Is the Dog Nicotine Toxicity Calculator?

Assess the risk when your dog ingests nicotine from cigarettes, patches, e-liquid or vapes — by weight and amount.

Nicotine is highly toxic to dogs. Cigarette butts, e-cigarette liquid (vape juice), nicotine patches, and nicotine gum all pose serious poisoning risks. E-liquid is particularly concentrated and dangerous — even a few drops can be lethal for a small dog.

Every result is based on published veterinary research and breed-size-specific growth data — not generic averages. This tool is completely free, works instantly in your browser, and requires no account or sign-up.

How It Works

Nicotine acts on nicotinic acetylcholine receptors throughout the body, initially causing stimulation (increased heart rate, blood pressure, agitation) followed by depression (weakness, respiratory failure). Absorption is rapid, especially from liquids and patches.

The toxic dose in dogs is approximately 1–2 mg/kg for mild signs, with the LD50 (lethal dose for 50% of animals) reported at approximately 9.2 mg/kg. The calculator estimates nicotine dose based on product type and quantity consumed. Sources: ASPCA Animal Poison Control, Plumb's Veterinary Drug Handbook.

Frequently Asked Questions

Is e-cigarette liquid (vape juice) dangerous for dogs?+
Extremely so. E-liquid concentrations range from 3mg/ml to 50mg/ml or higher. A 5ml bottle of 50mg/ml e-liquid contains 250mg of nicotine — enough to be lethal for a 27kg dog. Even a small spill that a dog licks can deliver a dangerous dose. Keep all vaping products locked away from pets.
My dog ate a cigarette butt — what should I do?+
Call your vet immediately. A cigarette butt contains approximately 5mg of residual nicotine — enough to cause mild toxicity in a dog under 5kg. Butts also absorb water quickly and release nicotine faster when wet. Do not wait for symptoms.
How quickly does nicotine poisoning develop in dogs?+
Within 15–60 minutes depending on the source and dose. Nicotine from e-liquid or chewed patches is absorbed faster than from cigarette material. Symptoms progress quickly from vomiting to tremors and potentially seizures without treatment.
