Unlike Mickey 's other animal friends, such as Goofy (who is also a dog), Pluto is a normal animal. Pluto does not speak, walk upright, or wear clothing. A significant departure from this was his speaking role in The Moose Hunt (1931), which was produced before Pluto 's characterization had been clearly defined. As Pluto made more appearances, it became common that he would not speak, but only vocalize in barks and grunts. Other ways of communicating Pluto 's thoughts occur through his facial expressions, and sometimes through the use of a shoulder angel / devil who speak directly to Pluto. (Mickey 's Elephant, Lend a Paw).
