History

kai kenThe 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.

Pugnaces Britanniae is a dog which is now extinct. There isn't certainty surrounding the origins of the dog but it is thought they descended from dogs brought to Britain way back in the 6th century BC already.

These are ancient dogs, and when you do research you find references dating back to centuries ago. In fact when you read of the Roman conquest of Britain you read of huge dogs, which the Romans referred to as Pugnaces Britanniae.

It is believed that the English Mastiff descended from the ancient Alaunt and Pugnaces Britanniae and that the dog was used as a war dog.

Description

kai ken puppy - descriptionThe 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.

Temperament:

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 Pugnaces Britanniae was a huge dog standing at roughly 67 to 75cm and weighing 52 to 110kg.

He was a heavily built dog, a Mastiff type dog that had a large head, broad muzzle with fairly loose skin around the mouth, brown eyes, a broad back and rump, muscular legs and floppy ears with a long tail. In fact the Mastiff, thought to have descended from the ancient Alaunt and Pugnaces Britanniae, gives you an idea of what the dog looked like. He no doubt has a short, smooth coat available in fawn, tan or brindle and with the black mask.

Temperament:

The Pugnaces Britannia was a naturally aggressive dog so it is to be expected that he wouldn’t automatically have been a good family dog, possibly being aggressive around children and other dogs. They were intelligent and were no doubt taught some simple commands.

They were also very territorial dogs, wanting to instinctively chase and attack unknown people and animals. They were strong minded, confident, loyal ad loving dogs towards their owners, being protective of them, wanting to please them.

Characteristics

kai ken dog - characteristicsThe 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 Pugnaces Britanniae may well have been a large dog and quite imposing to look at but he was in all likelihood a good-natured pet who got on well with his family members, being loyal and loving if brought up correctly.

Long ago dog training and socialization didn’t exist but a large dog like this would have to be socialized and trained to become obedient and an amicable all-rounder.

Health Problems

kai ken puppies - health problemsWith 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.

Progressive Retinal Atrophy:

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.

The Pugnaces Britanniae could live to 10, 11 or 12 years of age with good care. Large Mastiff type dogs like this would have had to watch out for common canine diseases such as hip dysplasia, cancer and bloat.

In those days, no screening tests were available for health problems like this. Gastric dilatation volvulus or bloat is a common health issue with large, deep chested dogs where the stomach fills with gas and the stomach twists. Its a life threatening disease.

Canine heart disease is another serious health issue with these mastiff type dogs. Early stages with heart disease show there may well be no symptoms at all. However, as the heart disease progresses towards congestive heart failure, the dog will have symptoms such as fatigue, difficulty with breathing, weight loss, a distended abdomen and coughing.

A dog with symptoms like this would have to see a vet immediately.

Caring The Pet

kai ken dogs - caringEven 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.

Diet:

The diets of ancient dogs were different to what they are today, as in those days there were no commercially manufactured dog foods. Dog owners in all likelihood tossed scraps to them which included starch.

Today a large dog such as the extinct Pugnaces Britannia would have no doubt been fed a high quality kibble from a leading brand and packed with minerals and vitamins specially formulated for a large dog breed.

Homemade food is also important, but not any kind of food – it has to be food which doesn’t upset the dog’s digestive system. Simple but nutritious food such as boiled chicken, brown rice or pasta, sweet potatoes, carrots and spinach is ideal for a dog, and when it is chopped up can be added twice a week to the dry kibble for a tasty, healthy treat.

Raw meat added in occasionally is also hugely beneficial. No dog should ever be without fresh, cool water constantly available.

Grooming:

As a short haired dog, the Pugnaces Britanniae would have required a brushing twice a week to rid the dog of loose hairs. Maybe in those days they didn’t check their dogs over to see that all was well, but today you would need to check the inside of the ears. If the insides were red, it could be a sign of an ear infection brought on by dampness, excess wax and dirt.

The eyes would need to be checked for discharge and the teeth checked a well. One rotten tooth can cause a lot of havoc. The nails of the dog would have had to be checked and clipped as well.

Exercise:

As a war dog, the Pugnaces Britanniae would have been fit. He is a big dog and while they require exercise such as walks and hide-and-seek type of games, he isn’t the kind of dog that would go running with you on a jog, as large, heavy dogs can overheat easily.
