Everything except chocolate Divegirl:
The naturally occurring theobromine found in chocolate, cocoa beans, cocoa bean hulls, cola, and tea, is responsible for the poisoning effect in dogs. Dogs are unable to metabolize this element quickly enough to prevent poisoning. The lethal dose of this agent is determined by weight and falls roughly into the category of 250-500 milligrams per kilogram of body weight. This equates to approximately 2/3 to 1 1/3 oz bakers chocolate for every 2.2 pounds though signs of poisoning begin to appear at a much lower ingestion levels.
