About the Kai
The Kai is a medium-sized spitz-type dog from Japan, from the mountainous Kai region, traditionally used for hunting boar and deer. It is sturdy, with pricked ears and a curled tail, and is best known for its brindle coat in shades of black, red or brindle. It is a rare breed, even in Japan, and has a reputation as a loyal, alert dog.
Temperament
Devoted to its family, alert and often reserved with strangers. Intelligent and can be strong-willed, so it needs early socialisation and patient, consistent training.
Exercise
Needs at least an hour of daily exercise, including walks and mental activities. It is happiest with an active routine.
Grooming
Short to medium double coat that sheds, especially seasonally. Brush weekly, more often when shedding.
Care & wellbeing
Keep weight in check and provide a secure garden, as it may follow prey. Dental care and routine checks are advisable.
