Mickey Mouse’s dog in the animated series House of Mouse is Pluto.
House of Mouse premiered in 2001 and centers on Mickey running a nightclub where Disney characters gather for dinner and entertainment. Pluto appears as Mickey’s familiar canine companion within this setting, continuing a relationship established across earlier theatrical cartoons and comic stories.
Pluto’s history predates the series by many decades. He first appeared in 1930 and became associated with Mickey after early stories established him as an expressive, largely non-speaking dog. His silent reactions provide comic contrast to the talking characters around him.
House of Mouse is sometimes confused with Mickey Mouse Works, another Disney television production that used short cartoons. House of Mouse is defined by its club setting and its large ensemble of Disney characters, while Pluto remains recognizable through his classic design and behavior.
