Both American Molossus and Shikoku are having almost same weight. Both American Molossus and Shikoku has almost same life span. Both American Molossus and Shikoku has almost same litter size. Both American Molossus and Shikoku requires Moderate Maintenance.
Based on the massive dog of Mesopotamia in 5000 BC, the American Molossus is the same dog recreated in the United States by and for the lovers of these giant dogs. The ancient Molossus was fierce to look at, massive in size, courageous and loyal. He was undaunted by any animal and stood up to any man attempting to hurt his master. When Rome fell the descendants of today’s Molossus were scattered and attempts to revive the breed have created carious large dogs. The American Molossus is the first true recreation that hits the mark.
The original Molossus was one of the most primitive of dogs, one of the earliest dogs that men domesticated. Their initials duties were the guarding of herds and homes against all enemies. They were incredibly loyal to their one master and stayed with him and protected him. These dogs also ate carrion and served the villages by eliminating animal carcasses. They could handle any other hunting animals such as wolves and large cats. This dog, although extinct was the ancestor of all the Mastiff-type dogs of today. The Molossus is said to be the ancestor of the St. Bernard, English Mastiff, Greater Swiss Mountain Dog, Bernese Mountain Dog, Newfoundland, Great Dane, Great Pyrenees, Rottweiler, Rottweiler and the Neapolitan Mastiff. Now these breeds have become the ancestry of the American Molossus.
According to Marcus Curtis, the founder of the new Molossus, the nearest relative of the American Molossus is the Neapolitan Mastiff. The Hines Bulldog, German Rottweiler, American Bandogge, and South African Boerboel together with the Neapolitan Mastiff were used to form the American Molossus. The goal of the founder was to make a great family pet and protector. It was specifically bred to be courageous, loyal and protective.
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.
This is a giant, massive dog in every way and this recently developed standard makes that very clear. The Molossus should be heavy bones, muscular with a lot of loose skin and wrinkles of all kinds, everywhere. He is an intimidating presence, with a massive square head, broad shoulders, height and mass. No, the American Molossus is not athletic, but he certainly is intimidating.
His head is massive in comparison to his body and it must be square. He has extensive wrinkles and pendulous lips and dewlap. The face is all folds of skin and wrinkles. Deep set eyes, drooping upper lids and lower lids as well as an intimidating expression. His brow is well developed with a marked frontal furrow. The nose is large, and the muzzle is about a third of the length of its head. It is short and broad. Everything about the head must be square. It’s neck and body are powerful and muscular. The chest is deep, wide and barrel like. The back is also powerful and muscular. The front legs are heavy and muscular while the hind legs are broad, strong, powerful and wide-stance. Do not remove the front dew claws. His tail is thick and wide then gradually tapers at the tip.
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.
The American Molossus is an intimidating massive giant bred for protection and guard duty. He is incredibly loyal to his family and courageous in his protection of them. They are guard dogs, not attack dogs. Their simple appearance is usually enough to frighten off anyone intending harm on their families. He is in reality a loving giant. He is intelligent and stable with a strong desire to please his owner. He is a calm yet vigilant presence in the home.
Because the Molossus is so large, it is recommended that the puppy be socialized and trained professionally. It takes a strong owner to handle this breed. They need to know the rules and have the rules consistently applied. The owner must be the pack leader.
Like all Mastiffs the American Molossus faces a variety of potential illnesses, some brought on by its size, some not.
This could easily be a function of its massive size. It is a degenerative disease and can cause the dog to become lame. In many cases the vertebrae can fuse, or severe pain can result. This is mostly seen in older members of the breed.
Male Molossus can contract this inherited metabolic disease primarily. It can be life threatening and very serious as it affects the kidney and the bladder.
This is essentially Cervical Vertebral Instability (CVI) and is caused by the pressure of the nerves in the neck and cervical spinal cord. This compression can cause deformity, pain and abnormal stance/gait. IT has been attributed to the nutrition needs and rapid growth of the Mastiff breeds.
Like all giant Mastiff breeds the Molossus can have skin issues from the wrinkles, dysplasia in the joints which we will address below.
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.
Remembering that this is a very, very large dog you need to be careful about nutrition and how fast your puppy will grow. American Molossus puppies need four meals a day until 12 weeks old. Then until they are 6 months old feed then 3 times a day. Finally, from 6-month-old puppy to adult – feed them twice in 24 hours.
At one year either feed them once or two small meals.
Many people feed their Molossus eggs, vegetables, fruit, and cottage cheese as ten 5 of the total for the day but avoid other table foods. The Molossus can become very picky about what he eats if you feed him too many table scraps.
In addition to the health problems listed above, the American Molossus is also susceptible to: Ditichiasis – Eyelashes that are in the margin of the eyelids and can cause eye irritation. May require surgery to correct.
Could cause blindness if not removed. Ectropian/Entropion: Eversion and inversion of eyelids which cause ocular irritation.
This is a degenerative disease which causes the dog to go blind. It is a disease the affects the retinal visual cells, first causing night blindness then day blindness. A DNA test is available for detecting PRA in all Mastiff breeds.
Common in large breeds and especially in giant breeds like the Molossus. Multiple forms and causes but all can cause pain and lameness.
Do to wrinkles and loose skin – check often for moisture and infections.
The is a problem based on a variety of possible causes. It happens when the puppy is between 6-16 months of age. Lameness occurs over time in one limb or in all. It can be intermittent and might be caused by diet, genetics, stress, autoimmune or metabolic issues or infection.
This issue is developmental as the dog’s toes turn either inward or outward, then as the condition advances the dog suffers fever, pain in all joints, lethargy and the inability to stand. This happens when the dog consumes too many calories for his activity level in the development times.
The American Molossus is not a couch potato. He needs to be walked at least twice a day and loves to play fetch. He will be greatly benefited by obedience training. Do not overdo it with exercise but make sure they don’t just lay around.
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.
