Though Scrappy officially debuted in the fall of 1979, there may have been hints of his existence in 1969, as he ".bore a resemblance to Spears's and Ruby's initial idea for a feisty little dog", which was one of the early ideas for the Scooby-Doo character himself, along with the "big cowardly dog" ultimately chosen. He was created to save the show's ratings which by 1979 had begun to sink to the point of cancellation threats from ABC, who were considering choosing between Scooby-Doo and an unnamed pilot from Ruby-Spears Enterprises which Mark Evanier had also written. In the first live-action theatrical film, video games, and commercials, he was voiced by Scott Innes. Lennie Weinrib provided his voice for one season in 1979, and from 1980 on it was performed by Don Messick (who also voiced Scooby).

Scrappy has appeared in a number of the various incarnations of the Scooby-Doo cartoon series. He is the nephew of Hanna-Barbera cartoon star Scooby-Doo. Scrappy-Doo is a fictional Great Dane puppy created by Hanna-Barbera Productions in 1979 with the catchphrases "Scrappy Dappy Doo", "Lemme at 'em!" and "Puppy Power!".
