The history of the American Mastiff is entirely tied to the old European Mastiffs but in particular the English Mastiff. The developers of the American Mastiff crossed the English Mastiff with the Anatolian Mastiff at the Ohio kennel, Flying W Farms. The founder of this breed is Fredricka Wagner. Because of this the English Mastiff and the American Mastiff look very much alike. The difference between the two is that the American Mastiff was bred to have less health concerns than the English Mastiff and without the drooling. In 2000 the CKC acknowledged that the American Mastiff and the English Mastiff were separate breeds.
The Sanshu was developed in Japan a century ago – in 1912 in fact.
It is a cross between the Chinese Chow Chow and the ancient Japanese Aichi. People who know these dogs say they bear a resemblance to other Inu breeds, but it has a straight tail and not the usual curved one that you'd expect.
The breed is rare and they aren’t recognized by any breed organization.
This crossing of the English Mastiff and the Anatolian Mastiff resulted in a Mastiff with a much drier, less drooling mouth than the other Mastiffs. This is a giant, massive dog – powerful and muscular. With a wide head that is rectangular rather than square. Their eyes are dark amber, and their ears are high on their head and rounded. With a medium size muzzle, black mask and heavy head, the American Mastiff is a handsome dog.
Their chest is broad, deep with ribs that extended backward. He has strong legs that are parallel and wide set. He also has a long tail. Puppies of the American Mastiff are born almost black and as they grow their coat color lightens. In addition, it is important that they have a wrinkled forehead as well and a scissors bite is preferred.
The Sanshu is a medium sized dog standing at between 50 to 55cm in height and weighing in the region of 20 to 25kg.
There is also a smaller variety. This dog has a wedge-shaped head with a tapering muzzle, dark almond-shaped eyes with small erect ears. The tail is long and is straight but it can bend over the dog’s back. The coat is short and coarse and can come in a number of shades such as tan, white, reddish, white and black.
The Sanshu is a dog that loves to please its owners. Even so, training and socialization should be given to this dog. He is an intelligent dog, and with training and socialization he becomes well balanced and able to respond to a few commands such as sit, come, stay and lie down.
These are loving, loyal dogs and bond closely with their human family. It is a true companion dog and makes an excellent guard dog too. He makes a great pet with children, if the children have been taught to be kind and gentle to animals and not climb all over them.
A love of children and devotion to his pack (family) is bred into the American Mastiff. He is non-aggressive unless you threaten his family or his children. Then he becomes courageous, protective and defensive. This is a gentle giant most of the time, however due to size and the need for strong leadership, the American Mastiff should be socialized and trained early. If they are socialized and trained they will be calm, gentle dogs. They will remain protective and alert, but they will be friendly with strangers. They love to please their people and being highly intelligent they learn fast.
Sanshu dogs are known for the exceptional companionship they offer. They are loving, loyal dogs, wanting to fit in peacefully with their human companions and eager to please.They are amicable dogs, willing to get on well with other dogs in the family too.
In exchange for such devotion, everyone who owns one of these dogs should be eager to ensure they provide well for their 4-legged family member.
American Mastiffs seem to have fewer health issues than other larger giant breed dogs. However, they can experience allergies as many large, wrinkled dogs do. They also might have a tendency toward eye issues, hip dysplasia, cancer and heart disease. Bloat might be the most life-threatening issue many American Mastiffs experience.
This dog from Japan is a fairly healthy breed, and you can encourage good health by ensuring he gets good food and adequate exercise.
Nonetheless, every dog can fall prey to some of the many dog illnesses there are, and some of these diseases can be skin allergies, hip dysplasia, bloat, digestive issues, cherry eye, cancer and obesity.
The condition of the eyes can give away some ideas of a dog’s health. Eye discharge can be a sign of an infection or an allergy. If your dog’s eyes aren’t clear and there is a constant discharge, talk to your vet and get to the root of it. Left untreated, there are some eye diseases that can lead to blindness.

Skin allergies are sometimes caused by insect bites or allergies to medication or food. You might see excessive itching, scratching, a nasty rash, watery eyes and chewing of the paws. Atopic dermatitis is an inflammatory skin disease and you will need to get your pet to the vet.

Giant breeds like the American Mastiff are known for growing rapidly as a puppy and therefore proper feeding and nutrition is essential. The slower your American Mastiff grows, the better.

As previously mentioned this breed is a fairly healthy one, There, are however, certain evaluations you should do with your American Mastiff puppy to be sure she is in good health. These tests would include an elbow and hip evaluation to check for dysplasia. He should have an ophthalmologist and cardiologist examine him as well. Most American Mastiffs will not have any problems, but these evaluations will help to prepare you if they do. The wrinkles in your dogs; face, around the eyes and muzzle must be kept clean as they can become infected if you don’t.
Unlike the way he looks, the American Mastiff is not a couch potato, but neither are they a high energy, exercise machine. They do well living in apartments or homes, with or without a fenced in yard. They need a long walk every day. They need mental stimulation through exercise and games. Make sure they learn to love to play so that they don’t become lazy as they age.

Try and include some raw meat into the diet as this can help in fighting off horrible skin diseases. Ensure there is always a bowl of fresh, cool water for him.
