With the Mastiff breeds, the rarest and the smallest is the Nebolish Mastiff. Bred to be more agile than the giant mastiffs, the Nebolish was developed in Canada. They were developed by crossing several breeds, such as the English Mastiff, Neapolitan Mastiff, Dogue de Bordeux, Bull Terrier, Bullmastiff, Boxer, St. Bernard, and Deutsche Dogge. Perhaps there was some Great Dane as well. It was also hoped that they would have better health than the rest of the Mastiff breeds.
There are also those who believe the Nebolish Mastiff is not a Canadian crossbreed but rather the re-creation of the giant dogs that lived with the soldiers of Alexander the Great. Still others believe the breed is still being developed and no standard is yet true. They believe the dog is a hybrid. No one knows the exact breeding lines today and not many are breeding the Nebolish today. Thus, the dog is extremely rare.
Only the American Breeder Association (ABA), the Canada Molosser Association (CMA) and the Dog Registry of America Inc. (DRA) recognize the Nebolish Mastiff as a separate breed.
These dogs are courageous, loyal and dignified like all Mastiffs. They are protective of their families or their flocks. They are loving, intelligent and even-tempered. They are known to be great with kids since they are patient and calm – easy to train.
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 Nebolish Mastiff is very much like all other mastiffs with the exception of height and weight. He has a large head, long legs, strong neck, oval shaped paws, wide chest and large bones. He has solid muscles, large ears and a wide snout. They usually weigh anywhere between 43 and 82 kg. They tend not to slobber like the other mastiff breeds as a result of their breeding. They have a black mask and tail may or may not be docked.
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.
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.
Yes, they are very good with children.
Agility and swimming
No – they don’t do well with apartments and small spaces. They need a large fenced in yard.
High but can be stubborn
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.
Bred to be much healthier than other mastiff breeds, the Nebolish has very few health concerns. They live twice as long as most other Mastiff and giant breeds at up to 14 years. The most often reported health issue is:
bloat – where the intestines and stomach organs are twisted or distended. Bloat can be deadly so don’t hesitate on treatment. Avoid it by not overfeeding after or before exercise.
Test for Hip dysplasia as it can cause lameness or arthritis.
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.
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.
Don’t overfeed and don’t feed too much protein in the first year. Feed 1-2 cups in two meals.
bloat – Tendency to become obese so don’t over feed. About 2-3 cups in 2 meals per day.
agility and flexibility
This intelligent breed actually enjoys training, toys and all kinds of mentally stimulating puzzles. They love water and are very good swimmers. They need an average amount of exercise - a couple walks per day. Need a large fenced yard. They make great therapy dogs and play catch.
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.
