Japanese Terrier vs American Hairless Terrier - Breed Comparison

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 Japanese Terrier is native to Japan and is a rare pure bred dog. It is believed that the dog comes from Smooth Fox Terriers who arrived way back in the 17th century.

Certainly he looks very much like a regular Fox Terrier. It is thought that these smooth Fox Terriers were then interbred with local, Japanese dogs and used to hunt rats. Gradually he became a lap dog and companion.

Planned breeding of the dog began in 1920, and it was in 1930 that the dog was admitted to the Japanese Kennel Club with a breeding program being started.

Today you will find the Japanese Terrier in his home country and small numbers elsewhere. He was admitted to the United Kennel Club in 2006.

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.

The Japanese Terrier is a small sized dog who stands at 20 – 33cm at the shoulders and weighs in at about 2 to 5kg.

He is a short, smooth haired dog with a tight skin and in colors of white and black. Sometimes you may find a little bit of tan color on the face too as well as 'freckles' around the neck area and legs. The black shading of the coat is essentially found around the head of the dog and also his ears.

His ears are set high on the head and are semi-erect, semi-floppy. The tail has always been traditionally docked, giving the dog a nice compact look but these days it is unfortunately often left long and then its a medium length tail which is thinly covered in short hair. The nose is black and the eye are brown, bright and alert.

Temperament:

Gentle, cheerful, intelligent, loving and loyal are some of the characteristics of the Japanese Terrier. People who have kept him as a pet will vouch for him being a wonderful companion.

He is an active dog, but he still loves to be petted and won’t do well if left alone and not part of his human family. Being a clever dog, he is easy to train, learning easily and quickly. He is quite amusing at times and you can even teach him some tricks.

He gets on well with other pets in the home as well as with children. He is alert and will make a good watchdog, alerting you to an intruder.

Because of the Japanese Terrier’s small size and sensitive nature, this breed needs a calm owner and a quiet household. It is not recommended for boisterous households.

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.

He is smart and gentle and loves nothing more than to sit on your lap in the evenings and be your reading- or watching-TV companion. Give him the right amount of attention as any other family member receives and he is guaranteed to make you an excellent, low maintenance pet.

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 Japanese Terrier has no particular health issues and has a lifespan of 12 – 15 years if looked after well.

There are always one or two illnesses to watch out for such as eye- and ear infections. Some dogs also develop conditions such as Patella Luxation. This happens when your dog's kneecap is dislocated. It can only be returned to its normal position when certain muscles in the back legs are relaxed and lengthened.

With this condition, your dog holds up one of his hind legs. This condition is more prevalent in small dog breeds.

The American Hairless Terrier has some food needs that might be different from other breeds. They should not be given food that contains soy, wheat or corn. 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.

Health issues

As previously mentioned the American Hairless Terrier has skin health issues and is also prone to hip dysplasia.

Exercise and games

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 Japanese Terrier is an active dog and will require exercise every day. He’ll love to join you on your walks or have ball games in your garden. He can adapt to life in the city or in the country but will always need to have good exercise.

Grooming:

The Japanese Terrier is a medium shedder and you want to be sure then to brush him twice a week to get rid of all those loose hairs.

Diet:

The Japanese Terriers will require the best commercially manufactured dog food, and instead of one large meal a day, rather feed him 2 smaller meals. You can mix some tasty home-made food into his dry kibble from time to time. Excellent home-made food would be something like cooked chicken, brown rice or pasta and some vegetables.

If you can, try to also include some raw meat occasionally. If you’re in any doubt as to how to feed your Japanese Terrier so that he remains healthy, speak to your veterinarian.

Your dog should never ever be without a continuous supply of fresh, cool drinking water.
