Alpha

Alpha is a blue and ochre Doberman Pinscher owned by Charles Muntz. He is the leader of the dog pack and is usually found with Beta and Gamma, his lieutenants. Like Dug, he has a collar that allows him to talk, but a minor malfunction makes him sound as if he'd been inhaling helium, giving him a squeaky voice. The real voice for Alpha's translator chip (after Muntz fixes his collar) is a deep, intimidating voice. Russell says he likes the high-pitched voice better than the intimidating one.
