Scoobert "Scooby"Doo is a Great Dane belonging to the character Shaggy Rogers. Scooby-Doo and Shaggy share several personality traits, including tremendous appetites and tendencies toward cowardice. Due to their said cowardice, Scooby-Doo, as well as Shaggy, would often have to be bribed by their cohorts (Velma Dinkley, Daphne Blake and Fred Jones) to go after the costumed villains with "Scooby Snacks," a biscuit-like dog treat or cookie snack, although sometimes, Scooby Snacks won't work on Shaggy, so he may get "Shaggy Snacks."
Scooby has some difficulty with pronunciation, and tends to pronounce most words as if they begin with an "R." His catch-phrase, usually howled at the end of every episode, is "Scooby-Dooby-Doo!" Don Messick originated the character's voice patterns, and provided Scooby's voice in every Scooby-Doo production from 1969 until Messick died in 1997. Hadley Kay voiced him in the Johnny Bravo-Scooby-Doo crossover episode. Scott Innes voiced Scooby-Doo in four late 1990s/early 2000s direct-to-video films, and Frank Welker (also the voice of Fred) took over beginning with What's New, Scooby-Doo? in 2002. Neil Fanning provided the voice of the computer-generated Scooby present in the two Warner Bros. live-action feature films.
Within the universe of the show, Scooby-Doo was born on the Knittingham Puppy Farm (owned by Mrs. Knittingham); his "full" first name is Scoobert.
