Scooby-Dum is Scooby-Doo's cousin, and a member of his team, the Scooby Doobies.

His catchphrase is "Dum, dum, dum, DUM!".

Physical appearance

He is a grey Great Dane with the same black spots on his back as Scooby-Doo. Besides his color, he's distinguished from his cousin by his red hat, buck teeth, and droopy muzzle.


Scooby-Dum is, above all else, as dim-witted as his name implies and overall completely useless. This spaced-out, unintelligent demeanor leads him to be both extremely brave or extremely cowardly, depending on whether or not he's actually noticed the danger near him is actually dangerous.

Like his cousin, Scooby-Dum has a big appetite, though does seem to as eagerly attend to it as his cousin; perhaps due to his slowness.
