Hokkaido Ken
A northern Japanese hunting dog long kept by the Ainu to face bear in deep snow. Bold, deeply loyal, and built for cold — which makes a humid summer the single hardest part of owning one.

Background and characteristics
The Hokkaido Ken, also called the Ainu-ken, developed on Japan's northernmost island alongside the Ainu people, working bear and deer in country that spends months under snow. Japan designated it a natural monument in 1937. The FCI standard (No. 261) gives 48.5 to 51.5 cm at the withers for males and 45.5 to 48.5 cm for females; most adults weigh 20 to 30 kg. Many individuals have blue-black spotting on the tongue, an oddity the breed is known for.
Temperament and living together
Standing in front of an animal much larger than yourself selects for nerve, and the modern dog still has it. Hokkaido are courageous, physically hardy, and strongly attached to their family, with a clear watchdog streak: they bark to report, and they do not back down from a strange dog. Same-sex conflict is common enough to plan around, and dog parks are rarely a good idea.
Exercise and play
Exercise runs to an hour and a half a day for an adult, and this is a dog with real endurance — two suburban loops will not empty the tank. Long hikes suit them, and winter is when they come alive. In heat the calculus flips completely: a coat engineered for Hokkaido snow does not shed warmth well in a humid summer, so exercise moves to early morning and night, and a dog left in a hot car or a sunny yard is in genuine danger.
Coat and everyday care
Grooming is straightforward but heavy. The harsh outer coat and thick, woolly undercoat need brushing two or three times a week year-round and daily for about three weeks during each seasonal blow. No trimming; do not shave the coat for summer, because the undercoat insulates against heat as well as cold.
A high-velocity dryer after bathing saves hours.
Home environment and care planning
The breed is generally robust. Discuss hip dysplasia and patellar luxation with a breeder, and note that collie eye anomaly has been identified in the breed, so ask whether the parents were tested. Outside Japan the Hokkaido is rare, and prospective owners in North America or Europe should expect a long search or an import.
