Overview
The Kai Ken is a medium-sized spitz-type dog from the mountains of Kai, now Yamanashi Prefecture, Japan. It is rare even at home and is one of six native Japanese breeds protected by the Nihon Ken Hozonkai.
It is intelligent, agile and brave, and was prized as a hunter and a watchdog. Its brindle coat earned it the nickname Tiger Dog.
History
The Kai Ken was separated from the old Nihon Ken landrace when the Nihon Ken Hozonkai was founded, and was named after Kai Province, where it is said to have come from. It hunted in steep, rugged country, taking serow, deer, wild boar and occasionally bear.
It was designated a national monument in 1933, and the Kai Ken Aigokai preservation society, formed in 1931, still guards the breed today.
Appearance
The Kai Ken is a medium-sized dog with a wedge-shaped head, prick ears and strong limbs suited to mountain life. The tail curls over the back or is carried in a sickle shape. Males stand about 46 to 55 cm and females slightly less.
The harsh, medium-length coat is brindle in red, medium or black shades. Puppies are born solid, and the stripes can take up to five years to fully appear.
Temperament
The Kai Ken is a natural hunter that is alert, brave and agile. It is reserved with strangers but devoted to its family, and makes a good watchdog. It is usually good with children and not typically aggressive toward other dogs.
Many love water, and some are known to cross rivers and even climb trees while chasing prey.
Care and exercise
This is an active dog that needs daily exercise, mental stimulation and a secure fence, since its hunting instinct is strong. Early socialisation helps its natural reserve with strangers.
The coat needs weekly brushing, with more attention during seasonal shedding.
Health
The Kai Ken is a generally healthy, hardy breed. As with any rare breed, responsible breeders pay close attention to genetic diversity.
