A Snapper Dog resembles a large, bright green dog with a massive head and an equally massive, toothed maw. Its ears are long, stand on end, and curl at the tips. It has a crooked, green tail and four short legs with no discernible digits on its paws. Its long, red tongue is often seen hanging out of its mouth. The Snapper Dog's large, yellow eyes each sport a black spiral pattern. It also wears a large, yellow collar with several conical, dark green spikes on it, though, because of the Heartless's size, it is worn around its waist instead of its neck. Its nose, paws, and the tip of its tail are all light green. Its Heartless emblem is on its rear.
