Alpha (Up)

Alpha is one of the main antagonists in Pixar UP

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 intimidating deep voice. Russell says he likes the high-pitched voice better than the intimidating one.

Alpha 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.

In the background, he can be seen panting with happiness once Muntz says to "treat" to Carl and Russell.
