Dog Chocolate Toxicity Calculator
Your dog ate chocolate? Estimate the toxicity risk instantly by weight, amount, and type of chocolate.
1 standard chocolate bar ≈ 1.5 oz.
Quick answer
It depends on the type and your dog's weight. Mild signs can appear around 20 mg/kg of theobromine; severe, life-threatening signs above 40–60 mg/kg. A few grams of dark or baking chocolate can be dangerous for a small dog.
Why chocolate is toxic to dogs
Chocolate contains theobromine and caffeine, which dogs metabolize slowly. Darker chocolate is far more dangerous — baking chocolate and cocoa powder have the most theobromine, while milk and white chocolate have much less. Risk is measured in milligrams of theobromine per kilogram of bodyweight: signs often start around 20 mg/kg, with serious cardiac and neurological effects above 40–60 mg/kg.
