The Hairless is prized for its unusual appearance. The Hairless has soft, humanlike skin, as well as tufts of fur on its paws ("socks") and tail ("plume") and long, flowing hair on its head ("crest"). The Hairless variety can vary in amount of body hair. Some have hair that has to be groomed to make the hairless appearance. Fur on the muzzle, known as a beard, is not uncommon. A true Hairless often does not have as much furnishings (hair on the head, tail, and paws); however, many of the dogs seen in the show ring are actually a "moderate" or "hairy" hairless that is shaved down. The very hairy hairless has a single coat, often with hairless parts on the body. The skin of the Hairless comes in a variety of colors, ranging from a pale flesh to black, and is often mottled. The Hairless Crested often lacks a full set of teeth, and this is often used to verify to some extent that the dog is a true Hairless and not a shaved Powder Puff. However no hair or some hair, the hairless pup is totally hairless at birth and carries the hairless gene as well as the puff gene and bred with a Hairless or a Puff can produce either a Hairless or a Powder Puff puppy.
