Toy Bulldog vs Kai Ken - Breed Comparison | Petzlover

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 Toy Bulldog hails from England, but it is now extinct.

It is believed that the reason for this is that there were different breeding groups working in different directions. One of the groups wanted a smaller dog and there was also an attempt to cross French Bulldogs with Bulldogs to decrease their weight, but this breed was also not developed.

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.

Temperament:

The Toy Bulldog was a loyal and affectionate dog towards his human family It’s a pity he became extinct because he was amusing and entertaining, a great friend and companion.

They were calm dogs and didn’t require a lot of space and would have adapted well to life in the city or the countryside.

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 Toy Bulldog was friendly, docile, calm and gentle although tending to be a little bit stubborn.

He no doubt made a wonderful pet and would have been ideal for single people, families as well as older people. He would have made a splendid pet, and would have been an indoor kind of pet.

Not particularly high in energy, he would have enjoyed some exercise just to ensure he didn’t put on weight. He’s extinct now, but there are other popular bull dog breeds, and something of him lives on in these modern bulldogs.

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.

It is believed that that these dogs were healthy in their day but were no doubt prone to some canine illness issues just like any other dogs.

They would likely have battled with eye issues such as cherry eye, as well as joint problems.

Cherry Eye:

Cherry eye in dogs may not mean your dog’s life is in danger, but left untreated it can cause bigger eye problems later on.

Unlike a human being, a dog has 3 eyelids, with the 3rd one giving added protection to the dog’s eyes. It’s job is to keep dirt from entering the eyes.

There is a gland in the 3rd eyelid which can move out of place and then it bulges. This is what cherry eye is. The eye becomes irritated and the gland produces discharge. It is best to get your dog to the vet who has the skills and know-how to push the gland back into place.

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.

Diet:

The Toy Bulldog would have needed healthy, quality food to remain healthy. It is believed he became extinct in the early 1900s. Maybe there weren't commercially manufactured dog foods then. Their owners possibly tossed them scraps from the table.

Any dog would have to receive a good quota of vitamins and minerals in their food to stay healthy. If the dog was around today, you would read on the packaging label to see what to give him and definitely include some tasty home-made food too.

Nothing spicy and exotic – just plain, boiled chicken, brown rice, sweet potatoes and spinach. Simple foods like this ensure a dog remains free of stomach ailments.

Every dog requires a constant supply of fresh, cool water.

The Toy Bulldog with his short coat would have been easy to groom. He would have required a brush twice a week.

He would have needed a little bit of exercise, preferably a longish walk.

You had to be careful with a dog like this. He didn’t tolerate the heat well. He was not suited for running or jogging and could have developed heat stroke and weakness with his excessive panting. All the huffing and puffing and sweating would have irritated his skin as well.

He would have needed a warm, dry place to sleep indoors. If he went outside, he would have required shade and sunshine to lie in.
