The Hokkaido Ken is a sturdy, medium spitz breed with a wide chest. They have smaller ears, and denser coats than the other Nihon Ken breeds due to the harsh, cold climate they originate from.
Their size (as per FCI standard) is 45.5cm-48.5cm for females; 48.5cm-51.5cm for males at the withers. Body height to length ratio should be 10:11 but females may be slightly longer. The Hokkaido can weight anything from 13kg-20kg. They live for around 12-15 years.
The Hokkaido comes in 6 coat colours. Red, white, black and tan, brindle, black, and sesame, with the last two being incredibly rare, even inside Japan. Pinto coats are considered a fault. They have thick, double coats, with course guard hairs, and a fine, thick undercoat. Hokkaido blow their coat twice a year, so be prepared for lots of shedding! They have a sickle or curl type tails.
