Dug

Dug is one of the protagonists of Disney/Pixar's 2009 film Up. He is a fun loving, Dog who speaks English by way of a translator on his collar, invented by his former master, Charles Muntz. Early in the film, Dug, one of Muntz's canine minions, is searching for a large bird that Muntz has been trying to capture for decades. He runs into Carl Fredricksen, Russell, and Kevin (the bird he is searching for). However, immediately after meeting Carl Fredricksen, he begins to idolize him and sees him as his master. He winds up switching sides, assisting Carl, Russell, and Kevin.

Role in the film
Dug is a husky Golden Retriever who belongs to Charles Muntz.

He is every ounce a puppy, and quickly becomes attached to Carl, who is at first hesitant to accept Dug. When he does, Dug expresses his joy in a manner that leaves no doubt that he prefers his new master.

Dug has a special collar that translates his thoughts to speech, made for him by Muntz.

During the end credits of the film, it is revealed that Dug had mated with another Golden Retriever (with similarities to him), and they had many puppies.
