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.
The Formosan Mountain Dog is most often known as the Taiwan dog and it is a landrace indigenous to Taiwan. It is a small to medium breed of dog that was semi-wild at one time. The colonialization of Taiwan and other foreigners help to fully domesticate the Formosan Mountain Dog. They were found to be very trainable and uniquely suited for the terrain around Taiwan. The dogs were easy to train and now serve as hunting dogs, stunt dogs, guard dogs, rescue dogs, therapy dog and personal companions. There are three types of Formosans two smaller types and one medium. However, the original pure Formosan Mountain Dog is getting close to extinction again because the government and people have provided no protection or conservation efforts for them. These dogs have been living in Taiwan in the mountains and were called Formosan Mountain Dogs when Taiwan was known as Formosa. They come from a line of Southeast Asian hunting/gun dogs and they are considered ‘rare’ now.
According to historian Dr. Sung Yung-yi, the breed went through 4 major catastrophes that affected their development. The first of these was the Dutch Establishment in 1624. The Dutch colonized Taiwan and imported both people and dogs. The dog they brought in was called the Flying Dog and was either Greyhound or Pointer. Eventually, the Flying Dog bred with the Formosan Mountain Dog. This along with the slaughter of dogs belonging to the indigenous people by the government, starting the decline of the original Taiwan dog.
In 1895, it was the Japanese acquiring Taiwan following the First Sino-Japanese War. The Japanese bred the Formosan Mountain Dog extensively with the own Japanese dogs. This further diluted the line and authenticity of Taiwan dogs.
This was followed by World War II when German Shepherds traveled with the US Army and they cross-bred with the Formosan. This was the third major dilution of the Formosan Mountain dog line. At the same time, the Japanese government considered the Formosan Mountain Dog a sanitation threat and barbaric. They massacred them in large numbers in the name of sanitation.
The fourth and final dilution took place during the Kuomintang Era beginning in 1945 with the arrival of the Chinese Nationalist Party. They brought with them the culture of eating dogs. During this time the economy of Taiwan took off and business people began to import their own foreign dogs that were high priced purebreds. These dogs bred with the Formosan and other Formosans were just abandoned to die. The ranks of the breed became very thin indeed. Today’s pure Formosan is highly valuable and extremely rare. Because of all the crossbreeding over the centuries, today’s purebred Formosan Mountain Dog is very different from the Taiwan dog of old. Today’s Formosan is loved all over the island and is a companion and watchdog.
Today there is an effort by Taiwanese ecologists to put together a research project that would study and preserve the Formosan in its indigenous form. Dr. Yung-yi led this effort. He located only 46 dogs with a pure pedigree, 21 females and 25 males. They let the Food and Agricultural of the United Nations know and the dogs were labeled close to extinction. Reproducing from the indigenous dogs to purify and increase the breed was the goal. The government was not very supportive.
Today the Royal Air Force is looking at the Formosan Dog to use for military security. They are currently only using German Shepherds and needed another choice. It was decided that the Formosan Mountain Dog had a better sense of smell, dexterity, alertness, and hearing as well as better padding on their paws.
Through these efforts and those of foundation stock breeders and owners, the Formosan Mountain Dog in its indigenous form was brought back. Some call this dog a purebred Formosan while others consider it a new type. Standards were presented to the FCI for registrations as a purebred. This debate continues today
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.
The Formosan Mountain Dog that was seen during Dr. Sung Yung-yi’s research is a medium-sized dog, athletic and fit. It has a deep chest and a slim waist. The ears are half-covered, the nose is black and there is a coating of black on the tongue. This black tongue is the most distinguishing attribute of the Formosan Mountain Dog. The breed has a strong jaw, the skull that is just slightly longer than the muzzle, which is flat and tapered, triangle face and almond eyes. They have a thick coat and upright, curved tail.
The dogs are known to be extremely agile with an ability to hop that is rare in dogs but helps when hunting animals like rats. The Formosan Mountain Dogs hunted in packs with each dog attacking the prey with one bite until it was too exhausted to fight them off any longer.
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 Formosan Mountain Dog is very child-friendly. He is affectionate and loyal to his family and protective of his children.
He is intelligent and has exceptional hunting skills. He is a good guard dog due to his alertness, but they can be fear-aggressive.
He is very adaptable to living in any location as long as there is somewhere for him to get adequate exercise. He is friendly to people and animals.
He is intelligent and learns quickly.
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.
Because there have not been any studies done on the health of the Formosan Mountain Dog, there is not a lot known about any inherent or genetic health issues. It would seem that some bloodlines are healthy, and others have some serious issues. Especially because there are no studies, it is important for breeders to test for eye issues and skeletal issues through the Orthopedic Foundation for Animals and the Canine Eye Registration Foundation.
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.
Feed a high-quality puppy food for medium size dogs at the rate of a ¼ cup twice a day until 8 months then ½ to ¾ twice a day until 12-16 months.
1 to 2 cups of high-quality dry food split into 2 meals per day.
Generally healthy breed. Keep clean and watch for mites.
This is an energetic breed and he needs a lot of exercise. He must have at least an hour of exercise daily but the more, the better. He loves swimming and jogging with his people. He’s athletic, smart and agile. He does well with field trials, tracking, agility, and obedience.
