Sparky

Sparky (voiced by Maddie Taylor) is a fairy dog that joined Timmy Turner and his fairy family in Season 9. He was introduced on the Season 9 premiere episode, "Fairly OddPet", becoming the second addition to the show's main cast, after Poof, in 2008. However, due to bad reception by the public, Nickelodeon decided to not have the character back for Season 10.
