The Hokkaido (北海道犬, Hokkaidō-inu or Hokkaidō-ken) is a breed of dog originating from Japan. Other names for the breed include Ainu-ken, Seta and Ainu dog. In Japan, its name is sometimes shortened to Dō-ken (道犬). The Hokkaido is native to the prefecture of the same name in Japan.
The dog is medium in size, with small, triangular, upright ears. The small black eyes have a rising triangular outline. The Hokkaido has a coat of long, stiff fur, and a second, shorter coat of soft fur. Colors include red, white, black, brindle, sesame, black and tan, and wolf-gray. Males are typically 50 cm (20 in) tall at the withers, females slightly shorter, with body masses in the 20 kg (44 lb) range. Dogs bred on continents outside of their native Japan may be smaller.
In 1937, the Ainu dog was designated in Japan as "a rare species protected by law" by the Ministry of Education and it was decided that the official name of the breed would be Hokkaido-Inu. However, the dogs are almost always called Hokkaido-Ken among the Japanese people.
The breed is extremely rare outside its native country.
