Mange is a vicious looking dog owned by Francis, who brought him to school one day for show and tell. Mange is a dog owned by Francis the bully. Like his owner, Mange is very mean and scruffy looking. According to Francis, he feeds first-graders to him to keep his coat shiny. He is a small dog with a square-shaped head, and has white fur with a gray muzzle. He also wears a black spiked collar. He was only seen in the episode "Transparents!" and the video game The Fairly OddParents: Enter the Cleft!. Francis brings him to show and tell for school, where he shows off a jar full of first-graders that he feeds to his dog to keep his coat shiny. Mange ends up biting Mr. Crocker in the leg, earning Francis a "D for Dog". Mange reappears at the end of the episode, after Cosmo and Wanda poof him into a box in place of a captured baby dinosaur originally wished up by Timmy Turner, foiling Mr. Crocker's plan to expose Timmy's fairies, and causing Mange to bite Crocker yet again. However Timmy ended up in detention along with his friends and Crocker due to Waxelplax thinking he faked his show and tell.
