Goofy is not a dog. Goofy is a cartoon character created by Art Babbitt for Walt Disney Productions. He is a tall, anthropomorphic dog-like character with a long, thin face and a protruding lower jaw.
While Goofy displays many dog-like characteristics, such as loyalty and playfulness, he is not actually a dog. He is not a member of the canine species and does not possess the same biological traits as dogs.
