Frequently asked
How much chocolate is toxic to dogs?
Toxicity depends on the dog's weight and the chocolate type — darker chocolate has far more theobromine. Signs often begin around 20 mg/kg of theobromine, with cardiac risk near 40 mg/kg and seizures near 60 mg/kg. Use the calculator to estimate your dog's dose.
What should I do if my dog ate chocolate?
Estimate the dose with this calculator, then call your vet or a pet poison line — especially for dark or baking chocolate, small dogs, or any sign of restlessness, vomiting, or a racing heart. When in doubt, treat it as an emergency.
