Yabba-Doo is a white Great Dane. He looks like his brother Scooby, but white instead of brown and his fur is visibly more unkempt than his mystery solving brother. He doesn't wear a collar, instead he wears a red bandana around his neck and a brown cowboy hat.
Yabba is a stark contrast to Scooby. He is brave at any given time, not only when it is necessary. He will do anything to protect Tumbleweed county, including cross dressing. He also pronounces his words clearly, albeit with an accent. He also cares for his nephew Scrappy-Doo, after the latter and Scooby went their separate ways. His favorite food is Chili Snacks, just like Scooby is with Scooby Snacks.

- He wasn't mentioned in the A Pup Named Scooby Doo episode Curse of the Collar, when his parents, brothers and sister celebrated the family reunion. Possibly because he wasn't born at the time, which would make him the youngest of Scooby's siblings. It's also possible he's just being ignored, since Yabba came from shorts that had no connection to the main series outside of Scrappy, who wasn't in Pup, either.
- His character model has a lot in common with Shooby from the What's New, Scooby-Doo? episode New Mexico, Old Monster.
- Yabba, along with Scrappy, was parodied in the Doctor Who tie-in novel, The Crooked World.
- ↑ Instead of "Yabba-Dabba-Doo!" This is due to the fact that it was already a popular cartoon catchphrase by Fred Flintstone from The Flintstones.
