The Pup-Mobile is mostly painted beige. Its roof is dark brown, the fenders are blue, the bottom frame is gold, and the hubcaps are white and blue. It is designed like a dog, to match its function: on the roof there are decorations shaped like dog ears and a tail; the front grille and headlights resemble a dog face; the front fender and license plate resemble a dog collar with a tag. The blue handles of the side doors and the blue lock of the back doors are shaped like bones. On each side there is a sign of a bone combined with a huckleberry fruit.
