Brian Griffin
Brian is the Griffin's family dog. Unlike most dogs, Brian is a walking, talking dog, that spends most of his days drinking extra dry martinis. Before living with the Griffins', Brian was nothing but a stray until he was kindly adopted by Peter. He is now literally Peter's best friend, and commonly gets drunk with Peter and his buddies at the Drunken Clam, a local bar. Brian is seven years old and often visits his psychiatrist, Dr. Kaplan, where he gets advice on his numerous emotional problems.
