Dog Chocolate Toxicity Calculator

⚠️ If your dog ate chocolate, call your vet or a pet poison helpline immediately — don't rely on this estimate. It only puts the theobromine dose in context.

The math behind it

dose (mg/kg) = ounces × theobromine per ounce ÷ weight (kg). Signs may begin near 20 mg/kg; over 60 mg/kg is dangerous. Darker chocolate is far more toxic.

Worked Example

15 kg dog, 2 oz milk chocolate → ~8.5 mg/kg.
