Find Kai Ken Puppies For Sale on Pets4You.com. Also known as Kai Inu, Tora Inu or Tiger Dog, these dogs have existed since medieval times in the mountainous regions of Japan and were designated a natural monument in 1934 due in part to the work of a dedicated breeder, Mr. Haruo. These are one person dogs, rather recalcitrant and headstrong, and are the least responsive of all the Japanese breeds. They make good watchdogs. Coat colors are black/brindle and red/brindle. Groom daily to keep the coat in great condition. These dogs weigh 35 to 40 lbs. and stand 18 to 23" at the shoulders. Contact the dog breeders below for Kai Ken Puppies For Sale.
