Bob Clampett minted the scenario that Charlie Dog would later inherit in the cartoon short "Porky's Pooch", written by Warren Foster, released on 27 December 1941. A homeless hound pulls out all the stops to get adopted by bachelor Porky Pig. Unlike later Charlie Dog entries, however, this earlier character manages to succeed to get Porky to adopt him. Mel Blanc, Joe Alaskey and Eric Bauza would provide the dog's gruff Brooklyn Bugs Bunny-like voice and accent, giving him a sly and clever disposition.
