Scrappy-Doo

Scrappy-Doo is a small talking Great Dane puppy, who is one of the main characters of the Scooby-Doo animated franchise. He is also the nephew of Scooby-Doo. His voice was originated by Lennie Weinrib, which was only a brief stint, and may be more fondly remembered by his replacement, Don Messick, who was also the voice of Scooby-Doo.
