Pluto (formerly known as Pluto the Pup) is an animated cartoon character made famous in a series of Disney short cartoons. He has most frequently appeared as Mickey Mouse’s pet dog. He also had an independent starring role in a number of Disney shorts in the 1940s and 1950s. Pluto is unusual for a Disney character in that he is not anthropomorphized beyond showing an unusually broad range of facial expressions or use of his front paws at key points; he is actually represented as a normal dog (unlike Goofy who is an anthropomorphic dog).
