According to the Chinook Club of America (CCA), the Chinook (pronounced Sha-Nook) was created in New Hampshire in the early 1900s by explorer and sled dog-driver Arthur Walden, who bred a Siberian Husky with a “Mastiff-type dog”.Chinooks make wonderful family dogs since they are amiable and develop close relationships with their humans. They need frequent exercise to keep their bodies and minds in good shape, even though they are not too active.Chinooks weigh between 50 and 90 pounds and have a shoulder height of 22 to 26 inches.Twelve to fifteen years is the estimated lifespan of a Chinook dog.
