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 Koolie's ancestors were both the smooth coated blue merle Collie as well as the Black and Tan Collie. The dog hails from Australia.
Looking much like the Heeler dog, the Koolie is thought to have got its name from German immigrants to Australia who couldn’t pronounce the name ‘collie’ properly, so the name came out as Koolie. The Koolie of today is a product of a cross between the German Koolie and the Australian Dingo.
The dog has been around for a long time and in 2000, the Koolie Club of Australia was formed. It was in 2004 that the Koolie was recognized by the Australian Sporting Registrar. In May 2006, the Stockdog Committee of the Australian Shepherd Club of America accepted the Koolie as a recognized and accepted herding breed.
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.
Known also as the German Koolie or German Collie, the Koolie is a working- or herding dog standing at between 40 – 60cm in height and weighing up to 24kg.
The Koolie's coat is a merle coat pattern in red or black and possibly with some tan and is mostly short and smooth, though it can be medium length too. Depending on the coat color – red or black – the nose and eyes can be either brown or black, although eye color can also be blue or yellowish.
The Koolie is such a wonderful pet who has some excellent characteristics to his name. He is active, energetic, fun, clever, friendly and playful, but if you have him trained and socialized he becomes even more of a great family pet. He is intelligent too and will require an owner who is steady, firm, fair and consistent. You wouldn't call him an aggressive dog
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.
Many people today like the idea of a ‘wild’ animal as a pet, and the Koolie, with his Dingo ancestry, can be a challenging dog breed to keep. People eventually blame these animals for having a poor temperament – meantime all they are essentially, are high-energy animals.
If you keep a Koolie, it will be better if you were a firm, kind, patient, consistent dog owner who understands the special needs of these kinds of dogs. They’re an energetic, care-free animals who will do better on a large property or farm as he is lively and will need a good deal of exercise.
He is quite capable of being a splendid pet with training and socialization and will settle down well to family life when he is loved and cared for.
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.
The Koolie is a long-lived dog and there are records of it being able to reach 18 years of age. Because they have a diverse gene pool, you won’t find many genetic problems with this dog.
It is always wise when you’re the owner of a dog, to look out for his health and wellbeing -
This is to prevent your Koolie picking up fatal diseases such as distemper and parvo-virus. Dogs can be vaccinated from 6 weeks of age for protection.
Working dogs like the Koolie are susceptible to parasites such as tapeworm. Worming of your dog can be included in your vet visit. Dogs with worms may show tell-tale signs such as being pot bellied, very pale gums, anemia and a dull, thinned coat.
A look at his droppings may reveal white segments or worms. Fleas are another kind of parasite and they breed quickly in warm months. Mange is a skin disease caused by small parasitic mites which can actually live inside the hair follicles of dogs. Veterinary treatment will be required.
This is when your pet’s temperature rises out of control. Dogs pant to reduce their body temperature so a dog puffing heavily is putting in extra work to reduce his body temperature.
Never leave you pet in a boiling hot car as the body becomes weak and he has difficulty with breathing. Without immediate treatment, the dog will collapse and die.

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.
This is a great breed for games if you make them small to match his size. He is energetic, athletic and playful. He loves agility, lure chasing and barn hunt activities. They need a good half hour of vigorous exercise per day.
The Koolie is an intelligent dog that will benefit from training and socialization to make him obedient and able to cope in diverse situations.
These dogs show an untiring enthusiasm for exercise and work and wherever you live, you will need to ensure that he gets regular exercise.
Only the very best - both home-made and commercially manufactured food - will be good enough for this energetic dog. Good quality food ensures health and longevity. Always see that there is a constant supply of fresh, cool water.
Make sure that your dog has a warm, dry place to sleep inside and that when outside, he has a cool, sheltered spot from the sun.
