In the early 20th century, in the small town of Wonalancet, New Hampshire a new breed of dog called the Chinook was born. Developed by Arthur Treadwell Walden, the breed is named after the first male ancestor who was named Chinook. The breed is a rare sled dog and the official dog of the state of New Hampshire. The Chinook was born of a cross between a large Mastiff-like street dog and huskies that were part of the Peary North Pole expedition.
Walden was an experienced slender and looking for a dog that was stronger, faster and had more stamina than his current sled dogs. Walden had years of experience including being the trainer and lead on Byrd’s 1929 Antarctic expedition and plenty of Yukon experience. Once he had the male Chinook he bred him with German Shepherds, Belgian Sheepdogs and Canadian Eskimo Dogs at the very least. He then bred those puppies back to Chinook until he had the type and traits he wanted. Following Walden, Julia Lombard and then Perry Greene took over mastery of the breed. From the 1940’s until he died in 1963, Greene was the only person who was breeding Chinooks. So, there were few left after his death. The breed neared extinction by 1981 with only 11 Chinooks available to breed. These dogs were divided between three breeders who saved the breed from becoming extinct.
In 1991, the United Kingdom recognized the Chinook and they were also registered with the UKC. At that time there were about 800 dogs in the breed. To increase the breed, there was a cross-breeding program that took Chinooks and bred them back to the breeds they considered to be apart of the original Chinook lineage. These 4th generation dogs might meet the standards of the Chinook Owners Associations Cross Breeding Program and be accepted as purebred.
In 2001 the Chinook was entered into the AKC Foundation Stock Service and added to the Miscellaneous class of the AKC in 2010. In January of 20113, the Chinook was finally granted full recognition and breed status within the AKC in the working group. He is a large working dog, rugged, patience, loyal and intelligent. He is one of the rarest breeds in the AKC.
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 Chinook is a muscular dog, making him a perfect fit to be a sled dog or a hauler of any type. He has a deep chest and powerful muzzle with enduring teeth. The ears can be pricked up or bent and wind-blown. The nostrils of the Chinook are solid black and wide, while the lips are black, the eyes look like almonds and are dark with intelligence in their glance. The feet are firm and oval, the pads cushioned and with dark pigmentation. The tail should not be docked.
The breed has a double coat and hair of medium length The undercoat is soft and thick while the outercoat is close to the body and coarse. The Chinook is usually a tawny, reddish color.
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.
This is a playful, affectionate and loyal breed. They have a special love for kids and always want to learn and please you. They are intelligent and very trainable. The Chinook is good with other dogs and as a sled dog they love to work in packs. They can be reserved but they are never aggressive or shy.
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.
For the most part, the Chinook is a healthy dog. There are however some issues they do have to contend with including:
Sometimes know as Chinook seizures this is really a movement disorder and perhaps not a true epilepsy.
This dermatitis may be hereditary. It causes itchy skin and is actual an immune system issue.
Chinook are known for a variety of gastrointestinal disorders manifested by diarrhea and vomiting.
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.
Don’t overfeed your dog. Based on how hard he is working for you feed twice a day. Dividing 3 to 5 cups into two meals.
Although the Chinook is still active in recreational sledding, he is mostly a family pet these days. Given this the Chinook need a good deal of exercise and competition. They are great at search and rescue, dog packing, agility, obedience, herding, carting and skijoring. They need some form of solid exercise for 30 to 60 minutes every day.
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.
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.
