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. While he exhibits typical dog behaviors like eating and rolling around in trash as well as licking himself, leaving dead birds on the porch, intensely fearing the vacuum cleaner, sleeping at the foot of Peter's bed, barking uncontrollably at black people (he blames his father), and having a tough time standing up in the car, 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, such as haggling over prices. Brian has also never graduated from college.
