Walt Disney's Pluto
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 48 Disney shorts in the 1930s, 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). Pluto is a V.I.P. member of the Mickey Mouse Club.
