The KKA Standard

This is a translation of the Kai Ken Aigokai standard. I tried to keep it as close to a direct translation as possible.

The Kai Dog Standard

Physical Proportions

Showing proper sexual dimorphism, and an unadorned unsophisticated air coupled with composed boldness. Movement light and nimble, the breed is agile and powerful with strong homing instinct and a propensity toward loyalty to one master for life.

The outer coat standing upright, undercoat thick, and animals should have a mane.

The breed is split into three coat colors, black brindle, medium brindle, and red brindle.

There are two body types, boar type, and deer type.

Height roughly 40-50 centimeters at withers.


Moderately thick, triangular in form, of good shape and angled forward, spacing between ears neither too wide apart or close together, lines clean and without looseness, and ears slightly larger than the other Japanese dog breeds.


More or less triangular in shape, the iris dark brown, which depending on coat color may show some shading.


Lips tight, with good pigmentation, teeth strong, proper bite.

Head & Neck:

Forehead wide falling to a moderate stop, neck having appropriate thickness and length, without looseness.

Back & Hips:

Line of the back straight, hips powerful and tight.


Tail thick and strong, either sickle tail or curl tail type, roughly reaching the hocks in length.


Robust with hocks especially well developed, firm while providing for excellent leaping ability and speed.
