¶Quick Facts
- The American Hairless Terrier is a small to medium-sized American terrier now kept mainly as a companion dog.
- The breed comes in two varieties: hairless and coated. Both belong to the same breed.
- The ideal height at the withers is 30.5–40.5 cm for dogs and bitches. The breed standard does not specify a set weight.
- It should be energetic, alert, curious and quick to learn, although activity levels can vary considerably between individuals.
- Its Rat Terrier ancestry is still evident in a strong prey drive, particularly towards small animals, even though bare skin limits the hairless variety in dense cover.
- The breed is recognised by the Nordic kennel clubs but not by the FCI.
The American Hairless Terrier is best suited to someone who wants an active companion and can combine everyday training with protection for bare skin. Having no coat does not make the dog allergy-free or remove the terrier instinct to hunt.
¶Appearance & Coat
The American Hairless Terrier should be agile, muscular and slightly longer than it is tall, with proportions of about 10:9. It should have medium bone and move freely and evenly while keeping a strong, level back. This is an athletic terrier, not a fragile toy dog.
The ideal height is 30.5–40.5 cm for both sexes. The standard gives no weight range, so proportions, muscle and body condition are more informative than an unofficial figure. Ask the breeder to show you how the parents look and move as adults.
Both the hairless and coated varieties are recognised. A hairless puppy is born with a soft natal coat that gradually disappears. By about eight to ten weeks, the body should be hairless apart from whiskers and possibly very fine down. The coated variety retains a short, smooth, dense and glossy coat. All colours and colour combinations are allowed except merle and albinism.
Hairlessness is inherited recessively and is associated with a variant in the SGK3 gene. A coated dog can therefore carry the variant without being hairless. This genetic form is not associated with the same effects on teeth and fertility as the dominant hairlessness seen in some other hairless breeds. That does not mean every dog must have a complete set of teeth: the standard accepts a scissor or level bite and does not penalise missing premolars.
Skin care should respond to the dog's skin and the weather rather than follow a fixed routine. A hairless dog may need a well-fitting coat in cold conditions and protection from strong sunlight. Check the skin for chafing, scratches or redness after play and walks. Dry skin may sometimes need an emollient, but recurring rashes, itching or inflamed areas should be assessed by a vet. The coated variety mainly needs routine brushing, nail care and checks of the ears and teeth.
¶Temperament & Personality
The American Hairless Terrier should be energetic, alert, curious and quick to learn. A confident individual will usually want to take part in family life and enjoy both company and purposeful activities. It also has a clear terrier heritage: it may react quickly to movement, keep watch on events outside the home and make its own decisions when something interesting appears.
Positive early experiences of people, dogs, surfaces, sounds and different settings matter. Socialisation does not mean that the dog must greet everyone. The aim is for it to handle everyday life calmly and look to its handler for guidance. Too few dogs in Sweden have completed BPH behavioural assessments for the results to describe the whole breed, so observe how the actual parents behave instead.
Activity levels vary. The Swedish breed club describes dogs ranging from fairly moderate to intense individuals that need a great deal of exercise and occupation. Ask how the parents and previous offspring behave on ordinary days: can they settle after activity, how do they respond to visitors and sounds, and how strongly do they pursue small animals?
Prey drive is a central everyday consideration. The breed's ancestors hunted rats and other vermin, and an American Hairless Terrier may regard mice, hamsters, guinea pigs and other small pets as prey. Do not assume that living together will be safe simply because the dog grows up in the household. Keep the animals securely apart whenever an adult cannot supervise them.
¶Training & Exercise
The American Hairless Terrier needs daily movement, mental activity and practice in settling. A fixed number of minutes will not suit every dog. A better measure is whether the individual can move in a relaxed way, use its nose, solve tasks and then rest at home without becoming restless or overtired.
Combine walks with scent work, brief training sessions, play and body-awareness exercises. The breed may enjoy activities such as nose work, rally obedience, agility and trick training when the demands suit the dog's age and physical condition. Adapt activities to bare skin too: dense vegetation can scratch, while cold or strong sunlight may call for shorter sessions, a different time of day or protective clothing.
Use clear cues, short repetitions and rewards the dog genuinely values. Its curiosity and ability to learn mean that many individuals spot patterns quickly, including unwanted ones. Reward calm behaviour at the door, voluntary attention outdoors and the ability to disengage from something the dog wants to chase. Harsh corrections risk creating conflict or uncertainty and do not teach the dog what to do instead.
Recall and stopping around small animals deserve high priority, but training does not remove prey drive. Use a lead or long line where wildlife may appear until the response is thoroughly proven in that setting. If the dog barks at noises or visitors, work both preventively and practically: block opportunities to stand guard at windows, teach it to settle in a chosen place and reward it for breaking off the alert.
¶Health
There are too few registered dogs in Sweden to describe the breed's health with great certainty. It is therefore misleading either to call the American Hairless Terrier generally healthy or to present a long list of diagnoses as if each were common. A prospective owner gets better evidence by reviewing the parents' results, illness among close relatives and the breeder's follow-up of previous litters.
The Swedish breed strategy recommends that both parents' DNA status for prcd-PRA and primary lens luxation, PLL, should be known before mating. A PLL carrier should have an eye examination close to the mating. Dogs that show signs of patellar luxation or have had corrective surgery should not be bred from, and the breeder should make sure that every puppy can hear before it leaves. Persistent allergy, skin problems and autoimmune disease in offspring should also inform future breeding decisions.
These are breed-club recommendations, not a compulsory health programme. Under the Swedish Kennel Club's 2026 registration rules, the only special provision for the American Hairless Terrier is that coat type is recorded; there is no breed-specific requirement there for prcd-PRA, PLL, patella or hearing tests. Rules can change, so anyone planning a litter should always check the current version.
As a puppy buyer, ask to see the DNA results and confirm which dog they belong to. A result for one genetic variant is not a general certificate of health. Also ask how the patellae have been assessed, how puppy hearing is checked, and whether close relatives have had skin, allergy, eye or immune-related problems. Because the breed was founded from a small number of dogs, the relationship between the parents and open follow-up also matter.
A hairless dog is not allergy-free. Dog allergens are found mainly in skin and saliva, and the amount varies between individuals, even within a breed or litter. Anyone with a dog allergy should not choose a breed on coat alone. Discuss the risk with a healthcare professional and spend time with the particular dog on several occasions before deciding; a brief meeting with another member of the breed offers no guarantee.
¶History & Origins
The American Hairless Terrier developed from the American Rat Terrier, a farm and hunting dog used to control rats and other small quarry. In the autumn of 1972, a hairless bitch was born in a Rat Terrier litter. The Scott family named her Josephine, and she became the foundation bitch of the breed. In 1981, she produced a litter of two hairless and two coated puppies, providing the basis for further development.
During the 1980s and 1990s, the population was built from few dogs, with matings between close relatives used to establish the hairless trait. This explains why genetic diversity remains an important part of breeding decisions. The coated variety is not an unwanted by-product but a recognised part of the breed and can contribute to a broader breeding base.
The United Kennel Club registered it as a hairless Rat Terrier variety in 1999 and as a separate breed in 2004. The American Kennel Club granted full recognition in 2016. The first documented import to Sweden arrived in 2005 and produced its first litter the following year. Swedish Kennel Club recognition has applied since 2017. The breed can take part in shows and dog sports in the Nordic countries but is still not recognised by the FCI.
¶Living with the Breed
An American Hairless Terrier can live in a flat if it receives enough outdoor activity, help to settle and training around noises in stairwells and outside windows. The content of daily life matters more than the size of the home. In a building with poor sound insulation, however, the owner needs to address alert barking early and provide an undisturbed resting place.
With children, adult supervision and respect for the dog's boundaries matter more than a breed label. Children and dogs should not be left alone together, and the dog needs a safe resting place where it will not be disturbed. Bare skin also makes rough play, sharp fingernails and careless lifting particularly unsuitable.
Living with a cat can work for some individuals, but prey drive makes calm, controlled introductions essential. The cat should have its own escape routes and resources, the dog must be prevented from chasing, and meetings should be supervised until their behaviour together is predictable. Small rodents and other prey-like pets must always be kept securely apart.
Being left alone is a learned skill, not an inborn breed trait. Start with very short absences when the dog feels safe and calm, and increase the duration only while it can remain relaxed. Persistent distress, barking or attempts to escape mean that training has progressed too quickly. Arrange care if daily life requires absences longer than the individual can manage.
In a Nordic climate, clothing for a hairless dog must function rather than merely look attractive. Check that coats provide warmth without rubbing beneath the forelegs or across the chest, and adapt time outdoors to wind, rain, temperature and the dog's movement. Strong sunlight calls for shade and may require skin protection. This extra care is central to the choice of breed, alongside the terrier's need for activity, training and safe management around small animals.

¶Frequently Asked Questions
Are American Hairless Terriers really hypoallergenic and good for people with allergies?
They are often a good choice for some allergy sufferers because they lack a typical coat and shed very little dander. However, no dog is completely hypoallergenic and people can still react to saliva or skin, so spending time with the breed before committing is important.
Do American Hairless Terriers need sunscreen and special skin care?
Their exposed skin is prone to sunburn and irritation, so they usually need pet‑safe sunscreen on sunny days and protective clothing if outside for long periods. Regular gentle baths, moisturizing when needed, and avoiding harsh chemicals help prevent dryness and skin problems.
How much exercise does an American Hairless Terrier need each day?
They are an active, athletic terrier that typically needs at least 45 to 60 minutes of physical activity daily. Mental stimulation through training, puzzle toys, and scent games is also important, since they are alert and can become bored without enough to do.
What is the temperament of the American Hairless Terrier around children and other pets?
They are generally affectionate, lively, and people‑oriented, and many do well with respectful, dog‑savvy children. With proper socialization they can get along with other dogs, but their terrier heritage means they may chase small pets like rodents or small reptiles.
Are American Hairless Terriers completely hairless, and is there a coated variety?
Not all dogs of this breed are hairless. There is also a coated variety with a short, smooth coat, and both coat types can appear in the same litter due to the genetics of the hairless trait.
What health problems are American Hairless Terriers prone to?
Overall they are considered a relatively healthy breed, especially compared to some other hairless dogs because they usually have full dentition. Owners should still watch for allergies, skin infections, patellar luxation, and endocrine issues, and choose breeders who perform appropriate health testing.
How suitable is the American Hairless Terrier for apartment living?
Their small size and lack of heavy shedding make them practical in apartments, provided their exercise needs are met. They are alert and may bark at noises, so consistent training and mental enrichment are important in shared buildings.
What kind of grooming does an American Hairless Terrier require if it has no coat?
They do not need brushing, but they do need regular skin maintenance. That typically includes gentle baths, nail trimming, ear cleaning, and monitoring for cuts, rashes, or clogged pores on exposed skin.
How cold tolerant are American Hairless Terriers and do they need clothing in winter?
They have very limited protection from cold and wind, so they usually need sweaters or coats in cool weather and should not be left outside for long periods. In very cold climates, short, supervised outdoor breaks and indoor exercise are best.
Are American Hairless Terriers easy to train and suitable for first‑time dog owners?
They are intelligent, eager to be with their people, and generally respond well to positive reinforcement training. First‑time owners who are prepared to provide structure, daily activity, and consistent socialization often find them manageable, but their terrier energy and alertness can be challenging without clear boundaries.¶Comparisons with other breeds
