Since he does not resemble any specific breed of dog, Goofy is most likely a mixed breed or a mutt. In Disney cartoons, Goofy appears as a tall, anthropomorphic dog with black fur, an off-white face and white gloves similar to those of Mickey Mouse.
There has been some confusion over whether Pluto and Goofy are both dogs because their presentation is so different. Pluto is treated as a pet by the other characters, while Goofy, despite also being a dog, is treated like any other of the anthropomorphic characters. Disney states that Goofy was originally conceived as a human character with the physical characteristics of a dog.
