Frequently Asked Questions
A toxic dose of theobromine is approximately 20mg/kg for mild signs and 40–50mg/kg for severe symptoms. Dark chocolate has ~150mg/oz, so a 10 lb (4.5kg) dog would show mild signs from ~0.6oz.
White chocolate contains very little theobromine (<1mg/oz) and is unlikely to cause theobromine toxicity. However, the high fat content can cause pancreatitis. Monitor and call your vet.
No. Baking chocolate, cocoa powder, and hot cocoa are more concentrated, not less. The theobromine survives cooking.
This calculator uses published theobromine values and established toxic dose ranges. It is a screening tool — always confirm with Poison Control or your vet, especially for borderline results.
Yes. Symptoms can take 6–12 hours to appear. If you're within that window, call Poison Control. If it's been over 24 hours with no symptoms and a small amount of milk chocolate, the risk is likely passed.
