Krypto, also known as Krypto the Superdog, is a fictional superhero dog appearing in American comic books published by DC Comics, commonly in association with the character Superman. In most continuities, Krypto is Superman's pet dog, usually depicted as a white dog of a generic pedigree. Krypto is sometimes depicted as resembling a Labrador Retriever, a plain white Dalmatian, a White Shepherd, or even a primitive dog such as a spitz-type dog such as a husky or a laika, a dingo (in Australian versions), a pye-dog (in Indian versions), or a tugou (in Chinese versions), but his specific breed is almost never specified.

Krypto has appeared in numerous cartoon television shows and films, such as a self-titled animated series; the television series Smallville, the HBO Max series Titans, portrayed by dog actors Wrigley, Digby, and Lacey; and the animated film DC League of Super-Pets (2022), voiced by Dwayne Johnson.
