Dog is one of the two main characters in CatDog. Dog is the more happy-go-lucky and more naive of the two. Dog is voiced by Tom Kenny.
Dog is a light brownish dog, with a purple circle nose, and three hairs sticking up on top of his head. He also don't have a whole body because his body is conjoind with his brother Cat (one at either end of its single body), he doesn't have a tail or hind legs, and they can't go to different directions so him and Cat have to go together at same places at all times.
