Why

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.

Signs to watch for if your dog has eaten chocolate

Signs can lag by a day or more, so no symptoms does not mean your dog is clear — call rather than watch.

What to do now

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.

Never induce vomiting and never give any medicine unless a vet tells you to — it can do more damage than the poison. What we will and won't tell you.
