Hero Overview
Goldstar


Dudley Puppy is the main protagonist of T.U.F.F. Puppy. Although he is still just a pup, Dudley's got the heart of a pack of full-grown dogs. He has no fear and has no pants. Reared on his mother's strict morals, he was born to stop all badness and meanness in its tracks! Now if only he could figure out how to follow that last rule.

Though chasing bones may excite him more than chasing bad guys, Dudley gives all he's got to keeping the streets of Petopolis crime-free. But that doesn't mean things always go smoothly. Dudley's a loose cannon and has a way of messing things up before he fixes them. That's why the Chief paired him up with his "purr-fect" partner, Kitty Katswell. Together, they're bringing D.O.O.M. down, one thug at a time.

Dudley is voiced by Jerry Trainor.
