Breed History:

The Chinook is a rare American sled and working dog breed developed in the early 20th century in New Hampshire by explorer and dog breeder Arthur Treadwell Walden. The breed began with a single dog named Chinook, who was bred from a Mastiff-type dog and northern sled dogs.

Walden aimed to create the ideal sled dog that combined strength, endurance, speed, intelligence, and a gentle temperament. The resulting breed became highly respected for pulling sleds during Arctic expeditions and outdoor work.

Chinooks were later used in sledding, cart pulling, farm work, and family companionship. At one point, the breed became critically endangered, but dedicated breeders helped preserve and revive it. Today, the Chinook is recognised as the state dog of New Hampshire and remains one of the rarest dog breeds in the world.
