Billy Boy is a 1954 animated short cartoon by Metro-Goldwyn-Meyer and directed by Tex Avery. It is a spin-off of Avery's previous creation, Droopy, and stars his unnamed Southern-accented wolf, who previously appeared opposite Droopy in The Three Little Pups and in Blackboard Jumble and Sheepwrecked. He would later serve as a basis for the character of McWolf, Droopy's archenemy in Droopy, Master Detective.
