Buster, a 10 month old terrier, is the proud graduate of three PetSmart training classes. He is also a life-saver. He saved his owner after he fell unconscious while recovering from surgery at home. Had Buster not intervened when he did, his owner might have died. With the ordeal now behind him, Buster is back to chasing squirrels and rabbits in the yard and playing with his beloved ball.
