History
The Chinook owes its existence to one man: Arthur Treadwell Walden of Wonalancet, New Hampshire. The breed derives principally from one male ancestor born in 1917, named "Chinook", who was Walden's lead dog and stud. "Chinook" derived from a crossbreeding of a female Greenland Dog from the Peary North Pole expedition with a large, tawny male Mastiff/St. Bernard mix.
Care and Health
Health issues include normal hereditary problems such as epilepsy, hip dysplasia, and atopy. Also common is cryptorchidism, which occurs in about 10% of all male dogs. Chinooks have a double medium long coat with a coarse outer coat and soft undercoat. Their coats are less dense when found in warmer climates. Daily brushing keeps them clean and their coat shiny. Bathing is only needed occasionally or as needed. Their nails grow fast so weekly trimming is recommended, with twice or three times a week for teeth brushing.
Fun Fact
They are now considered a rare breed of sled dog.
Good For
Although still used for recreational dog sledding by some owners, Chinooks today appear to be used largely as family pets. Individuals are also used for dog-packing, search and rescue, skijoring, and obedience and dog agility trials.
