Actor JERRY TRAINOR is working like a dog. The iCarly star voices a crime-fighting canine named Dudley in Nickelodeon's new animated series T.U.F.F. Puppy. Dudley and his partner, Kitty, protect the city from bad guys. But things don't ever go as planned, mainly because of Dudley. "He's not the smartest dog," says Trainor. "But he always saves the day--sometimes, by accident!"
