The American Hairless Terrier is a non- FCI recognized dog breed from the United States. The AKC officially recognized the breed in 2016.

History and origin

The American Hairless Terrier is, according to the regulations of the AHTA / AHTC (American Hairless Terrier Club), an independently developed dog breed since 1988, developed from the Rat Terrier ; recognition took place in 2004 by the UKC . Breeding began in early 1972, when a puppy had no hair in the middle of a litter from Rat Terriers. The owners crossed this bitch with other Rat Terriers in the hope that she would have hairless pups, which they did after several unsuccessful attempts.


The American Hairless Terrier is identical in physique to the Rat Terrier. The head is broad, slightly arched and in relation to body size. He has very soft and delicate skin, a deep chest, strong shoulders, a strong neck and long, straight front legs that give him a compact but elegant appearance.

It has triangular erect ears, but erect ears that fall forward in the upper part are also possible. Bitches tend to have more delicate bodies and faces.

Dogs are born hairy but lose hair before they are 8 weeks old. The skin color is usually brown, pink to gray, with gray to blue, gold, black to red clearly defined points. The older the dog gets, the bigger the points get. As with humans, the skin becomes darker in summer and pale again in winter.

UKC and AKC also recognize a variant of the breed with fur.


The American Hairless Terrier is energetic, alert, and curious.

Causes and Consequences of Hairlessness

The American Hairless Terrier is the only breed in which hairlessness is inherited in a recessive manner. This characteristic only manifests itself if a dog inherits the incriminated gene from both parents, whereby the homozygous state is not lethal, as is the case with other hairless breeds. The hairless version is born with sparse hair that the dog sheds within a month of birth (called hypotrichosis). The specific gene responsible for hairlessness in the American Hairless Terrier was identified a few years ago.

The hairless dogs need protection from the sun and cold winter weather.
