The Old English Mastiff as well as the Bulldog are the breeds behind the Bull Mastiff. The Bullmastiff was originally developed in England around the 1860’s. Gamekeepers in England wanted a large, brave, robust dog which could help with keeping poachers away from their large estates which kept game.
As these large estates dwindled, so did the need for the services of the Bullmastiff and later they were simply bred to be family companions. As more Old English Mastiffs were bred, the dog became lighter, so that light tan or fawn became the preferred color.
The breed was officially recognized by the English Kennel Club in 1924, and the American Kennel Club in 1933.
The Shikoku is from the Shikoku Island in Japan and they are very much like the Japanese Shiba Inu. There are six native Japanese dog breeds and the Shikoku is medium sized and sits in between the smaller Shiba Inu and the very large Akita Inu. All of the Japanese native breeds are members of the Spitz family. The Japanese have sorted their six breeds into 3 categories by size. Being medium size, the Shikoku is a member of the Shika-inus group. Others in this group are the Ainu Ken, the Kai Ken and the Kishu Inu. There are small differences between the three dogs in the Shika-inus group.
The Shikoku was bred to be a hunting dog in Kochi Prefecture to hunt boar and deer. Other names for the breed include Kochi-ken and Kishu dog or boar hound. This dog is considered to be the purest of the Japanese native dogs or Nihoken. They are today very , very rare. There are very few outsides of Japan, but some in North America are attempting to save the breed.
The are od Kochi Prefecture is a mountainous region with rough terrain that anyone outside of the area would have a hard time accessing. That is why the Shikoku is considered to be so pure as they were pretty well isolated in the mountains. The breeders were also isolated by the mountains and there was very little interbreeding. Although breeding the same dog, these different groups developed different lines of the Shikoku.
Documentation tells us that the number of originals lines was just two and these were the Western and Eastern Shikoku. The Western dog was known as the Mount Ishizuchi Shikoku and the Eastern as the Mount Tsurugi Shikoku. Within these two lines of Shikoku there are additional strains.
Within the Eastern line there is the Tokushima (lya) and the Koci-Aki strains. Within the Western line there is the Hata Uwahara, the Ehime-ken Shuso-gun and the Honkawa. Among these lines and strains, there are different coats and different colors; some heavier and some taller, but all figure into the development of the breed.
Finally, in the Showa Era the Japanese established the Dog Protective League and they began collecting the native dogs from around the country. They protected them so that the breed will go on. The Shikoku is today recognized as Foundation Stock by the AKC and it is fully recognized by the Japan Kennel Club, the Canadian Hound Club and the Shikoku has been declared a living Japanese “natural monument”.
Two bloodlines became the way the Shikoku were know after the war – the Honkawa and the Hata lines The Honkawa line were the descendants of the Choshun-go and the Hata line were the descendants of the Matsukaze-go. They bred the lines separately until 1955, when they mixed them to make the breed stronger. They are no longer considered separate in any way.
Because they are such primitive dogs, the Shikoku are good watch dogs and quite reserved with strangers. They need a lot of socialization to be a family pet but once they are, they make great companions. Intelligent, quick to learn and eager to please. Of the two lines of Shikoku dogs from the Western strains, the current Shikoku owes much of its current development to the Honkawa and Hata strains.
Bullmastiffs are large, brachycephalic dogs, and heights are between 61 and 68cm and the dog weight anything between 41 – 59kg. While it isn’t particularly tall, the dog is thickly set with a deep chest and strong, muscular legs. The Bull Mastiff has a powerful build and plenty of strength with an imposing look on his face. He is a powerful, active breed with a short coat which is also weather resistant and can be any shade of fawn, red or brindle.
The dog has a black muzzle and the skull is large and square. The ears are set high and are short and floppy. The tail was once docked, giving the dog an even more distinctive, powerful appearance, but these days, due to regulations, the tail is left long.
The Bullmastiff is a loyal, devoted, fearless, protective dog. When he belongs to a human family, he becomes a companion but a fierce protector too, being a territorial dog. They love being with their family and can be good with children too, and even other pets, but proper training and socialization will be important. They aren’t aggressive around strangers, though he does make a wonderful guard dog.
He is intelligent and stubborn and if you don’t want him becoming destructive, even though he is a low-energy dog, you will need to exercise him and walk him every day.
Today’s Shikoku is a medium sized breed with a Spitz like body – square with a head that is wedge shaped. The ears are pointed, and the tail is curved and feathered. They have arched toes and hard pads with dark, hard nails.
The two lines of the Shikoku are slightly different in built and look. The Honkawa strain is slender and athletic; agile and single coated. They have dark eyes and most of them are black and tan.
On the other hand, the Hata strain is much heavier boned, with the front more muscular than the rear. They have small ears, a wide skull and a strong undercoat. His eyes are shaped differently than the Honkawa. Their coats are also mostly red and tan.
Contrary to his formidable looks, the Bullmastiff is a gentle, affectionate pet when he has been properly socialized. He is a great pet for families and will guard them with his life. He is loyal and devoted but can be somewhat aloof, particularly with strangers.
He isn’t a highly energetic dog and he is more or less low maintenance and easy-going. Feed him correctly, give him a nice, warm sleeping spot to call his own and give him attention like he deserves as a family member. The Bullmastiff will reward you by being a solid and devoted companion.
The Bullmastiff is a generally healthy breed, but even so, the breed is known for having to contend with certain health issues. He doesn’t have a particularly long life span either and can live to be about 10, ll or 12 years of age. Some of the more common illnesses to look out for include -
This is a condition where the thighbone doesn’t fit properly into the hip joint. The troublesome part is that it can lead to arthritis, pain and lameness for your pet.
This is a worrisome, life-threatening condition for a dog, particularly for large, deep-chested dogs such as your Bullmastiff. Instead of feeding your Mastiff one large meal, it is recommended to feed him 2 smaller meals. Bloat occurs when the stomach is distended with gas or air and twists, restricting the normal return of blood to the heart.
Being isolated as they were, the Shikoku was a fairly healthy breed, no genetic testing has been done. Despite this they suffer a few of the same potential issues as other breeds their size.
Otherwise this is an agile and hardy breed with no known congenital health issues.
The Bullmastiff has a short dense coat which is looked upon as low-maintenance. He will require a brushing twice a week, being a light to average shedder. He is a dog that tends to drool quite a bit so you may need to wipe away slobber from time to time. Because his face has wrinkles, check the creases to ensure they remain free of dirt and food particles to ward off infection.
Check his ears at the same time, brush his teeth at least twice a week with special dog-toothpaste and brush and keep the nails trimmed.
Your large Bullmastiff will require high-quality commercial dog food but he will also need some home-made food in between such as rice, vegetables and meat. He is a large dog and will have to get an intake of raw meat too. Dogs denied raw meat can end up with skin problems as well as other health issues.It is better to feel your Bullmastiff smaller meals than to give him one large meal which he scoffs down quickly. Smaller meals will help prevent the most dangerous illness known as Bloat.
Ensure he has a steady supply of fresh, cool water.
Feeding the puppy Be careful with feeding the puppy and adult as the breed is known to have a tendency toward obesity. Fresh food is better as it is what the breed has been used to, but a high quality puppy kibble is acceptable. Feed three times per day.
2.Feeding the adult He is a high energy dog so feed a high energy food designed for a medium sized dog. Feed in two meals each day.
4. Games and Exercises You will need a fenced yard for this breed and time to play with them. If not, you would need time to walk her more than once a day. They love to play indoors as well, chasing balls, learning new things. The breed make great companions for hiking, swimming, play frisbee or catch outside. They do well at agility, rally, obedience and flyball.
