Though his name, personality, and even breed are determined by the player, the dog from Fable IIis always a faithful companion. Whether you're fighting trolls or looking for treasure, this dog is there to help out in a pinch. A faithful friend since childhood, it manages to save the Hero of Bowerstone multiple times throughout his or her life. In order to better serve its master, this loyal pooch refuses to age, lasting well over two decades for plot reasons. As the player changes their alignment, whether good or evil, the dog will do the same, emulating their master's morality. Unthinking and completely selfless, this dog easily earns a spot on this list.
