Can dogs eat chocolate?
Chocolate contains theobromine and caffeine (methylxanthines), which can cause vomiting, diarrhea, restlessness, abnormal heart rhythm, tremors and seizures. The darker the chocolate, the greater the risk; cocoa powder and baking chocolate are the most dangerous.
Good to know: White chocolate isn't safe either: little theobromine but lots of fat (AKC: pancreatitis risk). Cocoa bean hull mulch can also poison dogs (Merck).
