Dear Dr. Mirodone,
Is chocolate bad for dogs, and if so, how much would my dog, who is 20lbs, need to eat to get sick?
This is a great question to ask right before Halloween! It is true that cocoa can be toxic to dogs, even at small doses. Cocoa contains the chemicals caffeine and theobromine, both of which can have adverse effects in dogs. It is the theobromine, however, that veterinarians are most concerned about.
