Frequently asked questions about Dog Chocolate Toxicity Calculator

How much chocolate is toxic for a dog?

Theobromine toxicity starts around 20 mg/kg, becomes severe at 40 mg/kg and life-threatening at 60 mg/kg. The Dog Chocolate Toxicity Calculator computes mg/kg from weight, chocolate type and amount.

Which chocolate is most dangerous?

Baking and dark chocolate contain the highest theobromine; cocoa powder is the most concentrated. White chocolate is essentially non-toxic for theobromine but can still cause GI upset due to fat and sugar.

What symptoms should I watch for?

Vomiting, hyperactivity, tremors, rapid heart rate, seizures. Onset is usually 2–12 hours after ingestion. The calculator's risk levels mirror veterinary thresholds.

What should I do if the result is high?

Call a vet or pet-poison line immediately. Don't wait for symptoms — induced vomiting works best within the first 2 hours.
