Old English Bulldog vs Kai Ken - Breed Comparison

This is an extinct dog breed. It is believed that the dog came from ancient dogs such as the old Mastiff. The Old English Bulldog was the original English Bulldog but quite different from the modern variety, with longer legs as well as a longer muzzle and more aggressive.

It is believed that the Old English Bulldog was the ancestor to many breeds and there have been efforts to recreate the Old English Bulldog, bringing about quite a few new Bulldog breeds. Records are actually unclear as to its origins and when you read up on its ancestry, you see that a lot of the information is conflicting.

A number of breeders have attempted to recreate this extinct breed with some success, but it must be borne in mind that these recreations aren’t the Old English Bulldog, as the genetics of it are extinct.

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.

This dog is extinct but he used to be a fairly broadly set, muscular dog, taller than the bulldog of today.

The average height of this dog was 36 – 40cm, weighing in at about 18 to 22kg. One of the dog’s more noticeable characteristics was his lower jaw that projected quite a bit in front of the upper jaw. The dog was deep-chested, the head broad and the nose and muzzle short.

The breed was developed for bull baiting, but in England, with the adoption of the Act of cruelty to animals, there was a decline in the interest for the dog, leading to it becoming extinct. There are old paintings from the 1800s and one such painting, Crib and Rosa, gives an idea of the form and size of the Old English Bulldog.

Temperament:

The regular English Bulldog today is often confused with the Old English Bulldog but it is a far sweeter breed than the Old English Bulldog. It is believed that the Old English Bulldog was an aggressive dog, bred to be this way because of his role in bull baiting.

As a pet though, brought up as a companion, he no doubt would have made a loving, loyal pet.

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.

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.

Not much information is available on this extinct dog. Perhaps because of his history of being used for bull baiting, he wouldn’t have made a good family pet as he was too aggressive. He wouldn't have been a good choice for a first time dog owner and he wouldn't have been a good choice of pet for children.

He was possibly owned by a single person who made money from him. Small wonder then that he became extinct when he was no longer required for this role.

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.

This dog, although extinct would have battled with common dog illnesses that can still be seen in the modern bulldog today.

Brachycephalic Airway Syndrome:

Brachycephalic airway syndrome is all about upper airway abnormalities and can be quite a problem in your Old English Bulldog because of the shortened muzzle of these breeds. These particular dogs have a smaller upper jaw and an overcrowding of of teeth and you will see that effort is required to inhale. They breathe more easily through the mouth then the nose. They have noisy breathing, particularly during exercise and in hot weather.

Cherry Eye:

Dogs have 3 eyelids, and cherry eye is the term used for prolapsed nictitating membrane, or the 3rd eyelid, when the eyelid comes out of place and you get a pink mass. It is a common condition found in Bulldogs, a genetic problem where surgical intervention or medicine may be recommended.

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.

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.

If the Old English Bulldog were still around today, you would have cared for him like you would most other dogs -

Feed your Old English Bulldog puppy 4 times a day with high quality puppy food.

At 6 months of age you can be giving your young dog 2 meals a day.

Commercially manufactured food is fine if its a high quality one. Always check out the top 5 ingredients on the packaging – the first 2 should be protein or meat. Follow a simple, consistent diet to minimize symptoms. Your adult dog can have kibble and sometimes you can add in chopped boiled chicken, brown rice and vegetables such as sweet potatoes, carrots and spinach. A little bit of raw meat can also be added to the kibble once in a while. Never leave your dog without a constant supply of fresh, cool water.

Even though the dog is extinct, dog owners of that time would have had to watch their dogs for ticks and fleas and any of the common dog illnesses of that time.

The dog would have had some kind of grooming – a brush down a couple of times and he would have been checked for ear and eye infections.

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.
