The Chief is a main character in T.U.F.F. Puppy. He is a tough but good-natured flea who runs T.U.F.F. headquarters. In Internel Affairs it's reveled that his real name is Herbert Dumbrowski, he used to be T.U.F.F's top field agent, he has a bionic foot, and short-term memory loss. He seems to have a hobby of baking, although his cooking taste is awful. According to Keswick, he puts mustard in his cherry pies!
