The Chinook is one of the most popular dog breeds. In this guide we cover its origin, temperament, care and the conditions it is most prone to, to help you look after its health.
Origin and history of the Chinook
A breed created in the early 20th century in Wonalancet, New Hampshire (USA), by Arthur Treadwell Walden, who sought a sled dog combining strength, speed and a gentle nature. The foundation dog, named «Chinook», was born in 1917 from a cross between a Mastiff-type dog and a Greenland Husky. It is hardy, intelligent and loyal, an excellent family dog very attached to children.

Care and feeding
The Chinook needs a balanced canine diet suited to its size and age, with weight control and fresh water always available. Look after its dental hygiene, brushing according to its coat, nails and ears, and keep up with vaccinations and deworming. Regular veterinary check-ups are key to catching any problem early.
Exercise and stimulation
The Chinook needs daily walks and exercise to match its energy, plus mental stimulation through games, obedience or interactive toys. A dog that moves and «thinks» every day is a more balanced dog: the right exercise prevents boredom, stress and excess weight.
