What Is the Dog Chocolate Toxicity Calculator?
Instantly assess the risk level when your dog eats chocolate — by type, amount, and dog weight.
Chocolate is one of the most common causes of canine poisoning. The danger varies enormously by chocolate type — baking chocolate is 22 times more toxic per gram than white chocolate. Enter the details below for an immediate risk assessment.
Every result is based on published veterinary research and breed-size-specific growth data — not generic averages. This tool is completely free, works instantly in your browser, and requires no account or sign-up.

How It Works
The toxic compound in chocolate is theobromine — a methylxanthine that dogs metabolise far more slowly than humans. The theobromine content varies dramatically by chocolate type: white chocolate contains almost none (35mg per ounce), milk chocolate contains around 64mg, dark chocolate 150-400mg, and pure baking chocolate up to 450mg per ounce.
Risk is assessed by dividing total theobromine ingested by body weight to get mg/kg. GI signs begin at around 20mg/kg. Cardiac arrhythmias and seizures can occur above 40-50mg/kg. Doses above 100mg/kg can be lethal. The calculator converts your inputs and compares to these thresholds.
Veterinary Research
Every formula is derived from peer-reviewed veterinary studies and clinical guidelines, not guesswork or generic rules.
