What was Superman's dog's name?

The name of Superman's dog was Krypto. Krypto, also known as Superdog, was a fictional superhero appearing on American TV and in comic books and movies. Krypto is commonly associated with the superhero Superman.

In most continuities, Krypto is the pet dog owned by Superman and is usually depicted as a white dog with a generic pedigree. Krypto is sometimes depicted as resembling a Labrador Retriever, but his specific breed is never completely specified.

When he was first introduced to the public, Krypto possesses the same powers and abilities as an adult Kryptonian. His physical abilities are however proportionate to his smaller size and species. Certain of Krypto's sensory abilities (senses of smell and hearing) are more acute than those of Superman, just as an ordinary dog's senses are more acute than those of a normal human being. Krypto also has super-canine intelligence (approximately human level, though he still has typical canine traits and interests).Technically, Krypto is from another planet, so he's not actually dog, since dogs only come from Earth. He's some sort of species from Krypton that looks very similar to some breeds of Earth canines.
