He is the Griffin family's pet dog and one of their best friends. In " Life of Brian ", he dies after being struck by a car. However, two episodes later, in " Christmas Guy ", Stewie soon saw his past time traveling self and was able to steal his return pad and transport back to the point where Brian was killed. Before the car could hit Brian, Stewie pushed him out of the way and saved his life. Initially, Brian is a comparatively more grounded and reasonable character, acting as a decent foil towards Peter.
