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 Shepherd is another dog with an English name that was developed in the United States. They developed from British farm dogs that were brought to the United States in the 17th, 18th and 19th centuries by the Scottish and English as they settled in the New World. Tracing their line through working dogs and collies in Scotland and northern England, the settlers bred them with local dogs and each other. These working farm dogs were called English Shepherds, Scotch Collies, barnyard collie, farm shepherd, the cow dog, and the old fashioned shepherd.
The English Shepherd was appreciated by the settlers and farmers because he was a versatile dog that could herd their flocks and protect their homes as well. They appreciated his intelligence and ability to hunt vermin and be a companion for their children. English Shepherds were bred to work with a variety of livestock such as pigs, cattle, goats, sheep and fowl. They were used to hunt as well and were known to track racoons and squirrels and tree them. There wasn’t a more popular dog in the American Midwest and East in the 1800’s and 1900’s.
The breed is trustworthy, alert and independent. As the small family farms were replaced by large agricultural enterprises the English Shepherd’s numbers dwindled as well until he fell into the category of a rare breed. There were no clubs to support it and not AKC recognition. The UKC had a different dog registered as a farm shepherd.
Today’s English Shepherd is still a farm dog, but he also hunts, is a therapy dog, competes in AKC trials, and performs search and rescue duties. As a farm dog, they are still the most desirable due to their versatility in working with different livestock, guarding the home and caring for the children. They do these things in a gentle way if possible but can be tough if needed. They have great empathy for the livestock and for their human family. This makes him a great dog for the family. The English Shepherd has remained a farm dog, working dog more than a show dog, over all these years.
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 American bred English Shepherd is a medium sized dog that looks somewhat like an Australian Shepherd or Border Collie. They have tails, never come in merle coloring and their head is not as rounded as the Australian Shepherd. A working dog, its proportionally very well balanced. Because the English Shepherd is so popular across the country, doing a wide variety of jobs, there is some regional differences in the dogs.
The coat can be curly or straight with feathering around the tail, ears and legs. Their heads are slightly rounded but broad and the muzzle is also broad with a solid black nose except for the clear sable dogs whose nose is brown. The eyes show you how intelligent and strong this breed is, and they should be round, brown and oblique. The ears are close to the head and wide apart.
With a strong, muscular back and shoulders the English Shepherd can do almost anything you ask him to. His legs are strong and straight, and his hind legs are muscular. His feet are compact, oval and well padded.
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.
It may seem strange to talk about kindness in a working dog, but it is one of the defining traits of the English Shepherd, along with intelligence. The breed is extremely kind to everyone he lives with animals and people. Once he is secure in his job and takes in his children or his herd, he is one of the best caretakers around. He is an independent thinker, is easily trained, and highly affectionate. However, he does see himself as the boss and unless you establish yourself in that alpha role you could have problems.
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.
Like many other herding breeds, it has been found that about 15% of English Shepherds had a gene mutation called MDR1. This means they have adverse reaction and high sensitivity to many common drugs for dogs. This condition could be life-threatening so test your dog for it and know what you are up against.
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.
Remember the English Shepherd is a hard working dog. But if you don’t work him don’t overfeed him. Twice a day, he needs about one half cup of a good quality dry food made with an active, medium sized dog in mind.
In addition to the health concern listed above, the English Shepherd is also prone to:
Both elbow and hip dysplasia can plaque the English Shepherd as it does almost any active breed. Have your puppy tested as it can cause lameness and arthritis.
This is a herding breed and they need exercise. They need a job. They are intelligent and work oriented so make sure they have something to do. Take them to herding trails and have their herding instinct tested. Put them to work in flyball, agility, frisbee, tracking, obedience, rally, herding and showmanship events. Just make sure your English Shepherd has enough to keep his mind and body stimulated at a high rate every day.
