Dog Chocolate Toxicity Calculator

Q: How much chocolate is toxic to dogs?

Toxicity depends on the type of chocolate, the amount eaten, and your dog's weight. Dark chocolate and baker's chocolate are far more dangerous than milk chocolate. As a general rule, doses above 20 mg/kg of theobromine can cause symptoms, and doses above 60 mg/kg can be life-threatening.

Q: What are the symptoms of chocolate poisoning in dogs?

Early signs include vomiting, diarrhea, restlessness, and increased urination. At higher doses, dogs may develop rapid heart rate, muscle tremors, seizures, and in severe cases, cardiac arrest.

Q: What should I do if my dog ate chocolate?

Contact your veterinarian or an animal poison control hotline immediately. Do not induce vomiting unless specifically instructed by a veterinary professional. Time is critical — the sooner treatment begins, the better the outcome.
