Kai Ken vs Bull and Terrier - Breed Comparison | Petzlover

The Bull and Terrier is a blend between a number of Old English Terriers and the Old English Bulldog. It is believed that this extinct dog was the start of breeds such as the American Pit Bull Terrier and the Staffordshire Bull Terrier.

They were excellent for hunting rats and weren’t a true breed. The dog was popular in the British Isles and in the United States in the 19th Century. They became rare as different varieties of Bull and Terrier were bred and standardized.

Most terriers have a good deal of Old English Bulldog blood in them so as to provide them with the courage to fight and hunt prey, while the English Terrier blood provided a feisty temperament and longer legs for speed.

Around 1860, the Bull and Terrier breed split into 2 categories – the pure white Bull Terrier and the ones of color. The Bull and Terrier was never recognized as a standardized breed by any of the kennel clubs.

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.

There isn’t too much detail and information on the Bull and Terrier but we can be sure that with the cross between the Old English Bulldog and the Old English Terrier, he would have been a small to medium sized compact, muscular dog, standing roughly between 38cm to 50cm in height and weighing anything in the region of 11 to 22kg.

He would have had a big head, and most of the dogs had a medium to long tail. His coat was of many colors such as white, fawn, tan or brindle and would have been short and smooth.

As far as temperament goes, the Bull and Terrier would certainly be courageous, feisty, independent, strong and energetic. Socialization wasn’t available in those days but with training, this intelligent breed would be affectionate with his human family.

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.

Nobody seems to be 100% sure when the classic Bull and Terrier dog became extinct but it is strongly assumed that it was some time between 1890 and 1920.

People believe that there are actually surviving breeds that could be considered Bull and Terriers. One thing is sure, when you consider that the Bull and Terrier is actually made up of several breeds such as the Bull Terrier, the Staffordshire Bull Terrier, Boston Terrier and American Pit Bull Terrier then you can imagine the character of the dog – brave, hardy, intelligent, feisty, bold, confident and fearless. He was a dog who loved his human family and would have been both friend and protector.

These dogs have been popular around the world, and have had a strong influence in the development of a number of other breeds. Even today, breeders are always looking at ways to develop new breeds based on the descendants of the Bull and Terrier.

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 Bull and Terrier was no doubt a robust breed with few health issues. However his owners of that time would have had to be aware of eye diseases such as cataracts that could have lead to blindness.

Other health issues they would have had to contend with would have been hip and elbow dysplasia, a disease which can cause lameness in a dog accompanied with pain. Because the Bull and terrier was mixed with the English Bulldog, the dog owners would have had to be aware of respiratory health problems, as the Bull dog is a breed that is susceptible to these problems.

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.

Grooming:

Long ago the Bull and Terrier was developed to be a hunting dog, and because he was a blend of the English Bulldog and Terriers such as the Staffordshire Bull Terrier and English Terrier, he no doubt had a short coat that would have required being brushed down from time to time.

Diet:

The Bull and Terrier dog was bred for hunting, and he would have in all likelihood have caught some of his own food. He would therefore have got a lot of protein in. His owners would also have fed him some of their own food too which would have been eggs, home-made bread, rice, fresh vegetables and meat.

He would have had a good quota of raw meat in his diet too and this would have ensured that his coat was shiny and glossy, free of rashes. Dogs such as the Bull and Terrier wouldn’t have eaten commercially produced kibble as that was only introduced in the 1930s.

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.
