Houndoom is a quadruped, canine Pokémon that is mainly black with a long orange snout and an orange underbelly. It has small, red eyes and a black nose. Around its neck is a white band with a small skull-shaped pendant on its throat. There are two white bands on each of its ankles, as well as three rib-like ridges on its back. Houndoom has a long, skinny tail with a triangular tip and three clawed toes on each paw. On top of its head is a pair of long, curved gray horns. These horns are smaller on the female than the male.
In a Houndoom pack, the one with its horns raked sharply towards the back serves a leadership role. Leadership is determined by fights within the pack. Its gut is full of toxins, which are used to create fire. This gives Houndoom's fire a foul odor and the wounds it inflicts will never heal. Houndoom appears near volcanic areas. Its howling induces shivering in other Pokémon, and often sends them scurrying back to their nests.
