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 English White Terrier was developed in the 1860’s by a group of breeders from the Sealyham terriers, the Jack Russell terrier, and the Fox Terrier. These breeders were looking for a white terrier that could be more successful in the show ring than the current prick-eared English terrier. They named their new breed, the English White Terrier or the Old English terrier. In later years in the United States, the English White Terrier was mixed again with the Rat Terrier and the Old English Bulldog to create both the Boston terrier and the Bull terrier.
Although the breed did not last long it did have a prestigious ancestry that could be traced back centuries in England among ancient terriers. The word terrier was in use in England in 1440, showing that the dogs were well known at that time. Most historians agree that the dogs were even older than the 1400’s. It is believed that terriers who “went to ground” after prey, existed as far back as the time of Christ in England.
Most of these ancestors of the English White Terrier were not white. White terriers came onto the scene around the 1700’s.The first picture of white terriers appeared in 1790 when Sawre Gilpin, a British artist, painted “A Huntsman with Hounds Foxhunting” and the terriers in the painting were white with brown marks. Others began to show the same kind of terriers in their artwork – white coated. Before this it is believed that breeders killed the white terriers at birth because they were often deaf and inferior to the other terriers. In the early part of the 19th century, the white terrier began to be completely white with no markings. The Kennel Club recognized them in 1874 as the White English Terrier.
The breed faced many genetic issues, deafness and the Kennel Clubs felt there was no difference between the current White English terrier and the English White terrier despite the difference in their ears. The new English White Terrier had dropped ears instead of Prick-ears. They considered them to be the same breed and not even different types. They were the smallest of all terriers and considered to be a good pet but not a show dog or a working dog. Because of this it was not very popular, and it actually had been bred to be a show dog and not a working dog. The English White Terrier was not recognized by any Kennel Club and within 30 years it was extinct.
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 English White Terrier had a pure white coat with no markings of any kind. His coat was short, hard, and glossy and his body was firm, muscular and hard. The breed was small – almost a toy. They had a body like the Manchester Terrier. They had long legs and large feet. The tail was medium size and straight out from the body.
The English White Terrier had a very refined head with a fairly long muzzle. Their bite was even, and their eyes were brown, amber or black. Their ears dropped – unlike the pricked ears of the White English Terrier.
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.
The English White Terrier was affectionate and devoted to his family. It was the softest tempered of all terriers and made an excellent pet. Some of the English White Terriers were animal aggressive while others were not. Training was difficult because of the wide-spread deafness in the breed. IT loved to be cuddled and held. They were also tenacious and game for any type of fight or hunt despite their size and deficiencies.
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.
The breed was considered to be unhealthy for the most part and became extinct because of this. Many complained that the breed was inbred and had a weak constitution because of it. Deafness was prevalent throughout the breed. This deafness occurs in many white animals, but the English White Terrier had the highest rates among all white dogs.
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. Make sure your puppies get enough phosphorous and calcium in their high calorie diet. Free feeding is not recommended. Feed puppies up to 4 small meals per day and feed adults twice a day.
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.
It was best to feed the English White Terrier 1-2 cups of dry meal per day served in 2 meals.
As mention previously, the English White Terrier was congenitally deaf and had a weak constitution.
This little dog with all its problems was still a very energetic dog and needed considerable exercise. Owners had to develop exercises and games to keep the English White Terrier occupied as with any terrier. If they didn’t have a job or something to occupy their minds and bodies, they were destructive.
