Irish Mastiff Hound vs Chinook - Breed Comparison

The Irish Mastiff Hound is a huge dog – a mix of the English Mastiff and the Irish Wolfhound.

Both of these dogs have been around for a long time and actually have ancient histories. The Mastiff for instance has origins that date back to ancient times in China, while the Irish Wolfhound has origins that date far back to 391 AD.

Today this dog is regarded as an excellent companion for any home.

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.

This is a large crossbreed which can stand at 85 to 91 cm in height and weigh in the region of 47kg to 74kg.

He essentially has the short, smooth coat of the Mastiff but other dogs may well inherit the longer, more wiry coat of the Wolfhound.

They have a large head, some have a somewhat wrinkly face because of the Mastiff side, the ears are fairly small and floppy and the tail is long.
