It’s Pluto the Dog!
Pluto, aka Pluto the Pup, is a cartoon character created in 1930 by Walt Disney Productions. He is a yellow orange-color, medium-sized, short-haired dog with black ears.
Unlike most Disney characters, Pluto is not anthropomorphic beyond some characteristics such as facial expression, though he did speak for a short portion of his history. He is Mickey Mouse’s pet. Officially a mixed-breed dog, he made his debut as a bloodhound in the Mickey Mouse cartoon The Chain Gang. Together with Mickey Mouse, Minnie Mouse, Donald Duck, Daisy Duck, and Goofy, Pluto is one of the “Sensational Six”—the biggest stars in the Disney universe. Though all six are non-human animals, Pluto alone is not dressed as a human.
