How the Dog Chocolate Toxicity Calculator works

Methodology

Estimated methylxanthine dose = grams eaten × approximate methylxanthine concentration ÷ body weight in kg. Concentrations vary by product. Common veterinary references describe mild signs around 20 mg/kg, cardiac effects around 40–50 mg/kg and seizures around 60 mg/kg or more.

Only if a veterinarian or poison professional specifically tells you to and explains how.
