Derived from the Rat Terrier, the American Hairless Terrier was born in a litter of Rat Terriers in 1972.
The evolution of this breed is very different from other hairless breeds. The American Hairless Terrier was independently developed when a hairless pup was produced in a litter of normal Rat Terriers. The owners of this pup, Edwin and Willie Scott attempted to breed her to other Rat terriers but were not successful in having another hairless pup until years later. Then they had a litter with one male and one female hairless puppy.
From that point on they worked with a veterinarian and a geneticist to develop the breed until it was accepted as a separate breed from the Rat Terrier in 2004 and accepted into the AKC in 2016.
The breed is very rare and with hairless dogs breeding only produces about two thirds of the litter as hairless and one third as coated. If a hairless is bred to a coated terrier, the chances of getting hairless puppies are 50% hairless and 50% coated. It is very rare to get a hairless when breed two coated terriers. The difference between the American Hairless Terrier and other hairless breeds is that the hairless gene in most breed is a lethal dominant gene, but in the AHT it is a recessive gene.
The breed known as the St. John’s water dog is an extinct landrace breed. They were domestic dogs found in Newfoundland and at times were called the lesser Newfoundland. There is not much information available about the other breeds that went into its development. Hypothetically it is believed they are a mix of the Irish, Old English and Portuguese dogs bred to work.
It is also thought that other breeds in their family tree, descending from them, include the Golden Retriever, the Flat-Coated Retriever, the Chesapeake Bay Retriever, the Labrador and the Curly-Coated Retriever. The Newfoundland is also related to the St. Johns Water Dog through the line of Rafeirio do Alenteios that Portuguese fisherman brought to the island.
The breed was exported to England in the 19th century and early 20th. There the breeds of retrievers were developed. In Canada during this time frame restrictions were placed on dog ownership in order to encourage people to raise sheep. At the same time England imposed a long quarantine on all animals coming into the country in order to get rid of rabies. These two factors contributed greatly to the extinction of the breed. It seems the last two dogs were seen in a remote area in the 1980’s. All attempts to save the breed failed.
The American Hairless Terrier is similar to it’s breed of origin, the Rat Terrier, and the coated AHT looks very much like a Rat Terrier. They are small to medium in size, very muscular and have more refined features than the Rat Terrier. Their round eyes can be a variety of colors including amber, brown, grey, turquoise and blue. The tail is not docked but rather long and thin.
The AHT might have eyebrows and whiskers or they might only have whiskers. Their head is broad, and wedge shaped with upright ears. They are an energetic, social and intelligent dog.
St. John’s Water Dog is strong, medium sized and stocky. They looked more like English Labs than American Labs. They had a thick, short coat, loved swimming, had a lot of endurance and rudder tail. It was also described as a thin, black dog with short hair. They had white patches on their chest and feet. His nose was thin and tapered, his legs powerful, his chest muscular. The breed is quick, swims, runs quickly and is a fighter as well.
Never accepted by any major kennel club except as a foundation breed. They became extinct.
This is a curious, intelligent, little dog. They are terrific family dogs with a note to say they are better with older children than with younger. If they are raised with small children, then they are terrific with them. They are territorial, and the children become part of their territory. They will guard and protect them.
They need to play, and this is the biggest requirement for owners. Be sure you have time for them. This is not a couch potato dog. They have a lot of energy and can be destructive and “barky” if that energy is not dissipated. They are terriers through and through and love to “go to ground” whether going in holes they find or digging the holes themselves. They will go after small rodents like chipmunks. They need to be protected in these activities since their skin is vulnerable to scratches and cuts from brush. Their prey drive is strong, so it is important to protect them from themselves in this respect.
They are curious and feisty and every inch the terrier. Affectionate, friendly, and social it is also important to remember they can be scared easily, hurt if play is too rough, and this will trigger barking. They make very good watch dogs.
There are not many health problems bothering this sturdy little dog.
The American Hairless Terrier has limited breeding stock and it is still a rare breed. Its health problems are mostly related to its hairless state. The breed is highly susceptible to sunburn, rashes, pimples, and allergies. They often need clothing in all seasons to protect them from the heat of the sun or from the cold. The skin must be cleaned regularly often daily with soap and water. This is especially true if sunscreen is used as they are open to skin infections.
Hip dysplasia is also a common issue for this small breed.
There is no documented history of any genetic or hereditary illnesses in the breed. However, it seems rational to believe they suffered from ailments similar to Labradors and newfoundland though they are smaller dogs.

They need to be fed at least 3-4 times a day in small amounts as puppies and twice a day as adult. Be sure to avoid overeating and obesity. Puppies need about 400 calories a day whether you feed four times or two times. The adult American Hairless Terrier needs about 500-600 calories per day. This might be half a cup to a cup per day.
As previously mentioned the American Hairless Terrier has skin health issues and is also prone to hip dysplasia.
