Brian Griffin is an 8-year old talking white Labrador who has lived with the Griffin family since Peter picked him up as a stray. He also possesses various anthropomorphic qualities, such as the ability to speak intelligently, drive a car, and walk bipedally. He also has a particularly sharp wit. Peter is his best friend, despite Brian's vastly superior intelligence. On several occasions, Brian has had to explain Peter's inability to do various things.
