" Good for use until Level 12. He dies then, but comes back as an annoying dick. " - Wiki description
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. Earlier in the series, he used the catch phrase "Whose leg do you have to hump to get a dry martini around here?". 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. In "Brian Goes Back to College", it is revealed that Brian went to Brown University in Rhode Island, but did not graduate.
