Dudley Puppy

Dudley Donald Puppy is the protagonist of T.U.F.F. Puppy. He is a dim-witted and hyperactive mixed-breed dog who wears nothing more than a black shirt and has a habit of chewing his butt. Dudley is also quite gluttonous and childish. His catchphrase is "Hi gee gee." He is afraid of thunder and the dentist. He was voiced by iCarly cast member Jerry Trainor.
