Axehounds have angular heads which have two sensitive antennae and ear holes. Supported by six legs, axehounds have scaly hides. Their bodies are covered with a fusion of carapace and skin, smooth to the touch and more pliable than true carapace. Bigger axehounds may come up to a man's waist and can weigh as much as one ton.
They are lean creatures who run on four legs with the two front claws pulled in close to the body. They barely have shells on them, and (according to Lift) this makes them good eating.
Wild axehounds are larger and hunt in clusters. The Selay breed are said to be similar to axehounds but as different as are Parshendi and parshmen.
