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.

tosaKnown also as the Japanese Mastiff, the Tosa hails from Japan. In fact, these dogs come from the Tosa Province, so the dog was named after the region where they were bred.

It is why they are sometimes referred to as Japanese Mastiffs. The Tosa is a rare dog breed and unfortunately, the dog is still used in Japan for dogfighting.

Thought to be a dangerous dog breed, it is restricted in some countries.

The breed was developed in the 2nd half of the 19th century, with a number of dog breeds being involved to bring about a more powerful, braver dog.

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.

tosa puppies - health problemsThe Tosa is a formidable looking molossoid, but even so, this big, calm dog can succumb to illness. Some of these diseases you need to be looking out for include bloat,hip dyslasia and eye conditions.

Bloat for this dog can be life-threatening, and can often be because the dog is too hungry and he gobbles up his food quickly. Bloat is when gas can't escape, the stomach swells and twists – very dangerous. Rather give your dog two smaller meals – one in the morning and one in the evening, or even give several smaller portions throughout the day.

To help with eliminating health issues always choose a reputable Tosa breeder. You’re not likely to find one of these dogs in a dog shelter.

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:

tosa dogs - caringThese large, strong dogs do well on good quality food. If you opt to buy him commercially manufactured food, make sure it is the top quality one free of unwholesome ingredients such as preservatives, colorants and useless fillers.

Invest in the best quality ones that have nutritious minerals and vitamins. Try and give your dog some home-prepared food too – boiled chicken, brown rice or pasta, spinach, sweet-potatoes and carrots.

Never feed your dog things such as chocolates, peanuts, crisps, grapes, onion and food with spicy flavorings. This will just ensure digestive problems and having to get your dog to the vet.

Cool, fresh water should be available at all times.

Grooming:

The Tosa’s short coat isn’t going to require too much attention. A good brush twice a week will keep it free from loose hair and keep its shine and gleam. It’s why the dog is looked upon as being low maintenance.

Beyond that, he will need to have his nails trimmed. When brushing him, check him over for parasites – ticks and fleas, check for unusual lumps and look inside his ears for signs of redness.

Exercise:

These dogs are calm and fairly low-energy. Nonetheless, to maintain good health, he will need to be exercised. Ball games outside are always a good idea as well as nice long walks. Hikes into the countryside will be wonderful for this big dog.
