Philip is the secondary antagonist in the film Wallace & Gromit: The Curse Of The Were-Rabbit. He is Victor Quartermaine's pet Bull Terrier dog and a rival to Gromit.
Philip is smarter than he looks as he saw Gromit as a worthy opponent and was a skilled fighter against him.
While Victor hunted down the Were-Rabbit (which turns out to be Wallace), Gromit and Philip fought each other. In the end, Philip mistakenly bit his own owner trapped in the fake Were-Rabbit costume while the villagers chased him away.
