During the cold war, the Soviet Union developed the Black Russian Terrier as a working military dog. During the early 1950’s, the Red Star Kennel developed this breed and in 2004 by the American Kennel Club. The Black Russian Terrier is not really a terrier at all, but a mid-sized working dog used for hunting and guarding or as a pet. The Red Star Kennel is thought to have developed the BRT using a wide variety of breeds – as many as seventeen – including breeds like the Newfoundland, the Rottweiler, the Caucasian Shepard Dog and a Giant Shepard and an Airedale. So, you can see the wide variety and several more breeds were added. The Red Star Kennel in Moscow was owned by the state and they developed the BRT for specific working conditions and not for appearance. They did not really care how it looked except that it had to be black. In 1957 the state allowed a few puppies to be sold to non-military breeders. These breeders began to breed the Black Russian Terrier for appearance as well as function.
As these breeders worked with the dogs, they spread the breed throughout Russia and into Finland, Poland, Hungary, Germany, Czechoslovakia and Germany. From there they spread to Australia, Canada and the United States. The breed standard was developed in 1958 and by 1996 an updated version of the standard was developed to reflect the dog we see today. In 1996 the United Kingdom also got their first introduction to the breed. They are still rare outside of Russian or previous Soviet Union states.
The Kai Ken dog hails from Japan and is both an ancient and rare dog. In fact the dog was discovered in 1929 in the Kai province near Mount Fuji. The dog has the nickname Tora Inu in Japan which means 'Tiger Dog'. Maybe its got to do with the brindle striped coat or his bravery.
He falls into the working class category. In 1931, the Kai Ken Aigokai registry was formed to preserve the dog. In fact in this year Dasuke Adachi discovered these dogs and in 1934 was actually designated a Natural Monument in Japan and also protected by law.
The Kai Ken was recognized in 1934 by the Japanese Kennel Club. It is not 100% certain but it is thought that the dog was brought to the United States in the 1950s.
A little larger than a mid-sized dog, the Black Russian Terrier is strong, powerful, stable and alert. His head is block shaped and has a broad skull. The muzzle is square with a beard and mustache.

This is a healthy breed who faces some of the same issues other large dogs face such as dysplasia in the elbows and hips. Then they also face their own hereditary diseases such as Juvenile laryngeal paralysis, hyperuricosuria and polyneuropathy. They are also susceptible to heart disease, eye diseases, allergies, Panosteitis and hypertropic osteodystrophy. Let’s look at the major hereditary disease that are not so common.
This occurs when the larynx arytenoid cartilages stop working and don’t operate so then the adjoining muscles don’t work either and the dog cannot swallow without the possible damage to the airway and the cannot breathe properly during exercise or while panting.
This is a condition that can occur in people and animals. This condition can lead to kidney or bladder stones as there is too much uric acid in their urine.
Like any form of neuropathy, in this disease many different nerves are damaged, and this can cause weak reflexes and tremors. There are effective treatments however.
With a lifespan of 14 to 16 years, and given the genetic purity of the Kai Ken, you aren't likely to battle with congenital health problems with your dog, but it is always good to be aware of certain minor health issues that he could succumb to.
He can suffer from a few common dog diseases such as progressive retinal atrophy or hip dysplasia.
This is a disease of the eye where there is wasting of certain parts, and in this case the cells of the retina develop abnormally. This can eventually lead to blindness. It’s an inherited disease that can occur in pure- and mixed breeds, and dogs with PRA shouldn’t be used for breeding.
It isn’t a painful condition, and the first symptom usually noticed in a dog is night blindness where you may notice him bumping into things at night and being reluctant to walk around in the dark.
This is a large, working dog that needs healthy nutrition. Feed once or twice a day but do not overfeed. Don’t let your Black Russian Terrier get overweight. Proper nutrition for puppies is critical given the nutrionally based diseases discussed below.
This is a high energy dog that needs to work. He doesn’t just want to work, he needs to work. So, find him a job and one that includes a lot of exercise. He needs consistent and firm training but will respond well and excel in Obedience Trials. They are good at Schutzhund and agility. They need plenty of exercise and will be unhappy and destructive without enough and a job. He needs to burn off that energy.
Even though the coat is thick, the Kai Ken will require basic canine care, so a brush twice a week will be enough to keep the coat free of loose hair. He sheds more heavily a couple of times a year and then he will require more brushing.
He has always been used to hunt so he is a dog that will require regular exercise such as walks, hikes, swimming and ball games.
The nails of the dog should be trimmed regularly once they become long as long nails can be hazardous and can hook onto things, causing injury to the nail area.
The ears of the dog should be checked regularly for fleas and ticks, and teeth should also be brushed with canine toothbrush and toothpaste.
