This large breed dog is also known as the Mee Kyun Dosa. In spite of his huge size, he isn’t aggressive at all and is bred to be a companion dog.
He was originally developed to be a working dog. The dog was developed in the late 1800’s from European and Asian working breeds. Those interested in dog breeds suspected that a crossing of the Japanese Tosa-Inu with the Neapolitan Mastiff and the Dogue de Bordeaux brought about the breed. They also thought that the Saint Bernard and English Mastiff were brought in later on as well.
These large molosser dogs have been developed through years of inbreeding. It is one of the biggest dogs in Korea.
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.

Cherry eye is a fairly common health issue with this breed. It affects the tear gland of the third eyelid, and if left untreated, can lead to ongoing eye problems.
All dogs have a third eyelid, as well as two tear producing glands to lubricate the eyes. Its an important protective component to eye health in dogs. When the connective tissue that holds the gland in place is damaged or weak, there is a red protrusion of the gland from the lower eye. This is a congenital disorder.

Canine bloat, known as gastric dilatation and volvulus can be a killer disease for your pet, more so with deep-chested, large breeds.
Gas accumulation is known as bloat, and its the accumulation of gas which can cause the stomach to rotate. A dog can go into shock from bloat. The reason for this is that the stomach expands, putting pressure on veins. Blood can’t flow as it should and the blood supply gets cut off to the stomach.
Your dog could be vomiting, restless, the stomach hard and bloated or he may be drooling. Dogs who gobble their food down and eat just one large meal a day have an increased susceptibility to GDV than other dogs.
The wrong ingredients of a dog’s diet can also contribute to bloat. High quality food and feeding your pet smaller meals can help.
