Diaper Dog (formerly as Danger Dog) is Super Diaper Baby's sidekick. He defeated Deputy Doo-Doo and Rip Van Tinkle/Dilbert Dinkle with him.

He is Super Diaper Baby's best friend and pet who shares the same powers as him. His heroic, helpful, clever and obedient personality is a big help to him and Billy Hoskins when they're fighting crime and the forces of evil.
