As stated above, Philip is a Bull Terrier dog with white fur and brown spots.
Philip was the pet dog of Victor Quartermaine and was always seen by his master's side or at least assisting him in doing something. He appeared during Victor's confrontation with Wallace in the woods and was terrified of Wallace and his transformation into the Were-Rabbit. He didn't appear again until Victor tried to shoot the Were-Rabbit in 62 West Wallaby Street, however this was a trick set up by Gromit, When the two caught and locked him in a cage, although he did escape sometime later, thanks to Hutch. While Victor hunted down the Were-Rabbit, He and Gromit fought each other but this fight ended after Gromit dropped him from the bomb doors and he crashed straight into a bouncy castle, deflating it with his teeth. In the end, He mistakenly bit his own owner trapped in the fake Were-Rabbit costume while the villagers chased him away.
Philip is smarter than he looks as he saw Gromit as a worthy opponent and was a skilled fighter against him. His most prominent moment was a mock dog fight with Gromit using aeroplanes taken from a fairground attraction.
