The Bulgarian Shepard Dog comes from the ancient line of Molossers of Central Asia and Tibet, and the shepherds of the Balkans, Turkey and Caucasus. Among the oldest and most valued of the working dogs of Europe, the Bulgarian Shepherd breed was created by mixing the Balkan breeds with the dogs from Central Asia by the proto-Bulgarians around the 7th century. The Karakachanskoto Kuche was introduced to Bulgaria and accepted by the sheep herders. Mixing this breed in with the Balkan and Central Asian mix developed the Bulgarian Shepherd we know today. In the long run the original Karakachanskoto Kuche became extinct, replaced entirely by the Bulgarian Shepherd even in places where the new breed is still called by the Kuche name. Although the breeds are not the same, most of the dog world does not know the difference.
In Bulgaria however the Karakachan is a national treasure and the history of the breed runs deep. One Kuche could run up to 1200 animals and hundreds were used by the herdsmen in the mountains of Bulgaria. There were many regional types of Bulgarian Shepherds with very little difference between those types. These dogs were so prized by the shepherds that the dogs ate first before the people. The dogs however ate a vegetarian diet of milk, wheat, water and oats. The Bulgarian Shepherd lives a long life of often over 20 years. The Bulgarian Army made good use of these dogs early in the 20th century.
Following World War II, the wolves were close to extinction and property in Bulgaria was nationalized. There was no longer a need for a large force of working dogs. The Communist government exterminated large numbers of sheep dogs including the Bulgarian Shepherd. Only those species on government owned farms and in remote regions survived. When the government farms were disbanded in the early 20th century, these dogs were exterminated as well. Only those in the mountains survived. Commercial breeding of the Bulgarian Shepherd in the end of the century has resulted in controversy as other breeds came into the breeding program.
Use of breeds such as Sarplaninacs, Caucasian Ovcharkas, St. Bernards, Central Asian Ovcharkas and Bosnian Tornjaks in these programs resulted in Bulgarian Shepherd or Karakachans that were a lot different from the original breed. There is therefore some concern about the future of the breed in Bulgaria, yet they received official Bulgarian national recognition in 2000. Today’s Bulgarian Shepherd is a guard dog for both property and livestock.
The official standard for the breed came about in 1991 and in 2005 it was recognized by the Bulgarian State Commission for Animal Breeds. Only those dogs that meet this standard are considered “true” Karakachans. The Bulgarian Shepherds are willing to fight bears and wolves in defense of its family and flock. The dog is brave and loyal, dignified and powerful. They are recognized by both the Dog Registry of America, Inc. (DRA) and the Bulgarian Republican Federation of Cynology (BRFC) a member of the FCI.
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 massive, powerful and muscular Molosser, the Bulgarian Shepherd is strong, agile, powerful and fast. They are intelligent and reliable. They have a long, thick, harsh coat in white with patches of black. Their skull is massive and broad with a furrowed forehead. The muzzle is massive as well while the nose has wide nostrils and is fairly large. It has close fitting, thick lips with strong, scissor bite jaws. The Bulgarian Shepherd’s eyes are deep, oblique and small. They are either hazel or dark. They have an intelligent and confident, yet firm almost grim expression.
Their ears are low set, small and v-shaped. They sit close to the head which sits on a powerful but short neck. They have a broad back, well-muscled body with a deep chest and long, rough tail. Their gait is a trot with a spring in their step. There are two types of coats – longhaired and shorthaired with no undercoats.
The Kai Ken has always been used for hunting purposes. He comes as recommended for hunting people and those who are active.
It is a medium sized dog standing at between 43 to 56cm in height both male and female and weighing between 14 and 22kg.
The ears of the dog are erect, the muzzle is fairly tapered and the nose is black. The tail is bushy like that of a fox and curls over the back. The double coat of the dog is of medium length and harsh and is a brindle color in a reddish or black shade.
Puppies are born black and then the brindle stripe-like pattern comes in later. He has an athletic body and is a keen swimmer.
The Kai Ken is an intelligent dog, loyal to his human family while being somewhat reserved around strangers. They are amicable with both children in the home as well as other pets.
He is a friendly, intelligent dog, forming close bonds with his family. Have him trained and socialized and he'll make you a splendid pet who will be willing to guard you if anyone threatens.
One look at that bright face and you can see that he is an intelligent, independent dog. He is also courageous and fearless and makes a great watchdog, especially because he is naturally reserved and suspicious with strangers.
This is a working dog, intelligent and independent guard dog. Reserved around strangers but loyal and devoted with his family. Tolerant of children in their family if they were raised with them. Not only will she defend human family members, she will guard and defend household pets as well. He is quite capable of making her own independent decisions.

The Kai Ken is a working- and hunting dog, so he is used to being active and will want a home where he can be played with and exercised regularly.
He can be slightly stubborn and independent so training and socialization are imperative. This is also because the dog’s curiosity and his athletic skills can lead to trouble if he isn’t properly trained.
Treat him the way he deserves and you’ll see that he is able to develop a strong bond with you and be altogether an excellent family pet.
The breed itself is known to be healthy but they do face some of the usual health issues of the massive, giant breeds. This includes knee and elbow dislocation; hip dysplasia; bloat; entropion and osteosarcoma. All of these conditions require medical intervention, but bloat and osteosarcoma are the deadliest. Bloat needs immediate attention and osteosarcoma is a deadly bone cancer.
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.
These are large dogs with large appetites, but you want to keep them lean and active. Feed them at least twice a day with a high quality large or giant dog dry food. Four to five cups of food per day is the maximum.
Patellar Luxation – a floating kneecap or dislocated knee. Will cause lameness.
Osteosarcoma – bone cancer must be treated immediately as it is potentially fatal.
The Bulgarian Shepherd needs a good amount of exercise every day. Remember this is a working breed and they need a job. Long walks every day are essential for his well-being.
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.
