Frequently Asked Questions

Why is chocolate toxic to dogs?

Chocolate contains methylxanthines—specifically theobromine and caffeine—which dogs metabolize far slower than humans. It stimulates the central nervous system and cardiovascular system, leading to potentially fatal arrhythmias and seizures.

Which type of chocolate is the most dangerous?

Unsweetened baker's chocolate and dry cocoa powder are by far the most dangerous, containing 400 to 800 mg of theobromine per ounce. Milk chocolate contains roughly 60 mg/oz, and white chocolate has negligible amounts.
