Scooby is brown from head to toe with several distinctive black spots on his upper body and does not seem to have a melanistic mask. He is generally a quadruped but displays bipedal 'human' characteristics occasionally. Scooby also has opposable thumbs and can use his front paws like hands. He has a black nose and wears an off-yellow, diamond-shaped-tagged blue collar with an "SD" (his initials) and has four toes on each foot. Unlike other dogs, Scooby only has one pad on each of his paws (so that it was easier to draw in the Scooby-Doo Annuals).
