Wilf wants to be a witch's dog. His friends don't think he can as witches don't usually have dogs as pets - they have cats, spiders and bats. But when Wilf sees an advertisement for a witch's pet he decides to apply. He disguises himself as a cat which nearly works until his disguise falls apart. But Weenie the witch hasn't had any other applicants and so decides to give Wilf a try. He helps Weenie with her flying and her spells and ends up as Witch's Pet of the Year at the Annual Show.
