DogDay is an anthropomorphic orange-furred dog with black eyes, floppy ears, a black nose, and a yellow outer mouth and belly. His paws and ears, along with the left side of his face, have a copper-red color. Similar to the other Smiling Critters, DogDay is depicted with a wide toothless grin (the inner mouth shrouded in darkness), and he possesses a black zipper line running down his center, with the zipper sporting a gold sun pendant with orange sun rays.
