Shikoku is originated from Japan but Tibetan Mastiff is originated from China. Shikoku may grow 56 cm / 22 inches shorter than Tibetan Mastiff. Shikoku may weigh 37 kg / 81 pounds lesser than Tibetan Mastiff. Both Shikoku and Tibetan Mastiff has almost same life span. Both Shikoku and Tibetan Mastiff has same litter size. Both Shikoku and Tibetan Mastiff requires Moderate Maintenance.
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.
The Tibetan Mastiff is still considered to be a primitive breed originating in Tibet centuries ago. The breed was developed to guard property and livestock. They still do this as well as being a much loved family dog and a show dog as well. There is very little history that is documented for the breed prior to the 19th century.
Believed to be centuries old with ancestors who are mastiff like dogs that developed into two different types of Tibetan Mastiffs. These types are the Tsang-Khyi and the Do-Khyi. The Tsang Khyi were guardians for Tibetan monks, while the Tsang-Khyi guarded flocks for nomadic shepherds and in villages.
The first Tibetan Mastiff was imported in 1847 to England and presented as a gift to Wueen Victoria, from India’s Viceroy. By 1873 there was an English Kennel Club and the breed was labeled a large dog from Tibet and entered into the EKC Stud Book.
The next year the future King Edward VII, brought another two Tibetan Mastiffs to the United Kingdom to show in 1875. The first breed club began in 1931. The world wars interfered and no new dogs were imported to England until 1976. Two dogs were given to the President of the United States in the late 1950’sbut were not bred and it wasn’t until 1970 that any more were imported. The US Tibetan Mastiff Club was not founded until 1974 and they were first entered in a National Specialty show in 1979.
In 2007 the AKC recognized the breed as a working dog since 2007. It’s hard to find a purebred Tibetan Mastiff in Tibet anymore.
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.
Both types of Mastiffs can be present in the same litter, so that both larger and smaller pups are present. Both types are well-muscled and structured. Today’s dogs being developed in China and the West are much larger than the previous ones. These dogs would be less useful to the nomads and cost too much to feed. Today’s dog is very large with a large head and a long double coat. This coat can be black, brown, gold, and blue, with or without tan markings. There are now a few white Tibetan Mastiffs being bread.
The breed standard for the Mastiff is different in the West than in the East. In the East the breed is broken into two categories – the Lion Head and the Tiger head.
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.
Though considered a primitive dog and isolated for several centuries, so they should not have as many genetic or inherited conditions as other dogs with more cross and in-breeding. These are the potential health issues they might develop:
Elbow and Hip dysplasia – can lead to lameness and arthritis.
OCD Osteochondrois Dissecans – this is also an orthopedic condition when the soft tissue growth is abnormal in the joints. It is painful and the joint is stiff. Don’t breed a dog that has this condition.
Panosteitis – Canine growing pains. Inflammation of the long bones in large dogs as they grow. They will eventually out grow it. Pain can be managed through medication.
Autoimmune Hypothyroidism – Hormone deficiency leading to flaky skin, weight gain and lack of energy. Can be managed through medication.
Canine Inherited Demyelinative Neuropathy – If your Tibetan Mastiff is going to have this condition, they will have it by six weeks of age. Weakness in the hind legs leading to paralysis.
Bloat – deadly if not treated immediately and related to dietary habits.
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.
Don’t feed the puppy too much protein as you want to prevent Panosteitis and growing too quickly. Do not overfeed. Feed 4-5 cups of high quality large breed puppy food in 3-4 meals day.
4 to 6 or more cups of a high-quality dog food daily, divided into two meals. To avoid bloat do not feed before or after vigorous exercise.
Calm and laid back when inside.
They need 20-30 minutes of vigorous exercise and play daily. They prefer to play with other large dogs.
