Alpha is a doberman pinscher owned by Charles Muntz.

He was defeated by Dug trapping him under the helm and sticking a conical airship istrument housing over the Doberman's head as "The Cone of Shame".

Alpha later appeared in Dug's Special Mission, along with Beta and Gamma.


  • Alpha seems to hate it when others say that his voice is weird, due to his broken collar which makes him sound like a chipmunk.
  • Like Dug, he has a collar that allows him to talk.
