Alpha

Alpha is a Doberman Pinscher owned by Charles Muntz. He is the leader of the dog pack and is usually found with his second and third in command, Beta and Gamma. Like Dug, he has a collar that allows him to talk but a malfunction makes him sound as if he'd been inhaling helium. The real voice for Alpha's translator chip is a resonant, intimidating bass. Russell notes that he likes the high-pitched voice better than the intimidating one. He has a very condescending and proud disposition, and looks down on all the other dogs in the pack. It should be noted that Alpha is the character's rank in the pack, rather than his name, as Dug became the new Alpha after defeating him. He is voiced by Bob Peterson.
