Chocolate contains methylxanthines (theobromine and caffeine). The darker the chocolate the more it holds — baking chocolate and cocoa powder are the most concentrated, white chocolate the least. It can cause vomiting, an abnormal heart rhythm, tremors and seizures.
Call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 straight away. Tell them what your dog ate, roughly how much, and when, and take the packaging with you. Don't wait for symptoms — with several poisons the harm is done before a pet looks ill.
