The toxicity of chocolate depends on its theobromine content, which varies among different types of chocolate. Dark chocolate, baking chocolate, and cocoa powder contain the highest levels of theobromine, making them more toxic than milk chocolate or white chocolate. For example, baking chocolate can contain up to 16 mg of theobromine per gram, while milk chocolate contains roughly 1.5-2 mg per gram. Therefore, even a small amount of dark chocolate can be dangerous for pets.
