Nicotine Toxicity CalculatorCanineFeline

Calculate nicotine toxicity risk in dogs and cats. Estimates total nicotine dose in mg/kg based on product type and amount ingested. Covers cigarettes (whole and butts), cigars, nicotine gum (2 mg and 4 mg), nicotine patches (7, 14, 21 mg), and e-liquid/vape juice. Clinical signs appear within 15–30 minutes of ingestion. Mild signs (vomiting, drooling) at <1 mg/kg, moderate toxicity (tremors, tachycardia, diarrhea) at 1–4 mg/kg, severe signs (seizures, respiratory failure) above 4 mg/kg, and potentially lethal above 9.2 mg/kg (canine LD50). E-cigarettes and e-liquid are especially dangerous due to high nicotine concentration. Used for tobacco poisoning triage, cigarette ingestion emergencies, nicotine patch or gum exposure, and e-cigarette/vape toxicology assessment. Common queries: 'dog ate cigarette', 'dog chewed nicotine patch', 'cat ate nicotine gum', 'dog drank vape juice'.
