Poochyena's body is gray, with black coloration on its face, feet, ear insides and underbelly. The coloration on its underbelly, however, is not entirely continuous, with the coloration on the throat being separate from the coloration on the lower belly. Poochyena's eyes have yellow scleras and red irises and its nose is also red. Two of Poochyena's fangs poke out of its lower jaw, and the fur on its lower back near its tail is rumpled and shaggy. On the bottom of its feet, Poochyena's paw pads have been seen to be gray. Poochyena's main coloration is swapped when it evolves.
