History

american mastiffThe 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.

st john s water dogThe breed known as the St. John’s water dog is an extinct landrace breed. They were domestic dogs found in Newfoundland and at times were called the lesser Newfoundland. There is not much information available about the other breeds that went into its development. Hypothetically it is believed they are a mix of the Irish, Old English and Portuguese dogs bred to work.

It is also thought that other breeds in their family tree, descending from them, include the Golden Retriever, the Flat-Coated Retriever, the Chesapeake Bay Retriever, the Labrador and the Curly-Coated Retriever. The Newfoundland is also related to the St. Johns Water Dog through the line of Rafeirio do Alenteios that Portuguese fisherman brought to the island.

The breed was exported to England in the 19th century and early 20th. There the breeds of retrievers were developed. In Canada during this time frame restrictions were placed on dog ownership in order to encourage people to raise sheep. At the same time England imposed a long quarantine on all animals coming into the country in order to get rid of rabies. These two factors contributed greatly to the extinction of the breed. It seems the last two dogs were seen in a remote area in the 1980’s. All attempts to save the breed failed.

Description

american mastiff puppy - descriptionThis 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.

They had a thick, short coat, loved swimming, had a lot of endurance and rudder tail. It was also described as a thin, black dog with short hair. They had white patches on their chest and feet. His nose was thin and tapered, his legs powerful, his chest muscular. The breed is quick, swims, runs quickly and is a fighter as well.

Never accepted by any major kennel club except as a foundation breed. They became extinct.

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.

Caring The Pet

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.

Health issues

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.

Exercise and games

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.
