Which dog breed is this?

The Chinook is a rare breed of sled dog, developed in the state of New Hampshire during the early 20th century. The Chinook is New Hampshire's official state dog.

Standing 21 to 27 inches (53 to 69 cm) in height at the withers and weighing 55 to 90 pounds (25 to 41 kg), the Chinook is balanced and muscular.

The United Kennel Club (UKC) breed standard states, "The ideal coloration runs from light honey color to reddish-gold. Black markings on the inside corners of the eyes are preferred. Dark tawny to black markings on the ears and muzzle are preferred. Guard hairs on the tail may be black. No white markings are allowed.

The Chinook is an affectionate and playful family companion with a special devotion toward children. It is a willing worker who is eager to please and enthusiastic to learn.

The Chinook is highly trainable, adaptable, and versatile in his abilities. Gregarious with other dogs, the Chinook works well in teams and within family packs. The Chinook is a dignified dog; some may be reserved with strangers but should never appear shy or aggressive.

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.
