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.
Northern China is the original home of the Chow Chow. In that region of China, the breed was known as the Songshi Quan – “the puffy-lion” dog. They have also been known in China as the “Dog of the Tang Empire” or the Tang Quan. The Chow is believed to be an ancient breed that the Foo Dog, or stone dog guardians of Buddhist palaces and temples, is modeled after. It is one of the most ancient of dog breeds that are still around today.
It is believed that they have existed for around 2000 years or perhaps even as far back as 3000 years, starting out in Mongolia and migrating to China. The ancientness of the Chow Chow has been validated through DNA testing. In China all those centuries ago, the Chow Chow was born to be a working dog. They hunted, herded, guarded and pulled carts. They went on quests with the Mongolian armies when China was invaded, as well as when the Mongolians invaded the Middle East and Europe later on.
Today’s Canadian Kennel Club has about 350 Chows registered while the AKC gets 10,000 new registrations every year.
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 Chow really does look like a small lion with a black tongue. The dog is sturdy and square with erect, small ears on a broad skull. They have a very dense double coat. Their eyes are deep set and look like almonds, while they all have that very distinctive purple or black tongue. Their lips are also distinctive with their blue color. The nose is black, but some Chows might have a blue nose. The tail is curly.
These are medium size dogs when it comes to height and weight, but they are powerfully built for their size. Their power is in their compact body holding the energy and strength of a much larger dog. Its hind legs are almost entirely straight, unusual for any dog. They get their lion appearance from the huge ruff that stands behind their heads. Their chest is broad and deep.
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.
Loyal and true to their family and those they know; the Chow Chow is a little standoffish with strangers. They are very protective and usually attach themselves to one or two people. They are intelligent but stubborn, which can affect your training with them. They need to respect their people and Chows respect hose who take care of them. They can be aggressive toward dogs of their same sex especially if those dogs are the same breed as well.
They are known to be very clean and many have compared them to cats in that regard. They appear to be dignified and refined. They are usually very quiet but very adaptable dogs.
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.
Although an ancient breed that obviously has survived many centuries of trials, the Cho Chow of today is prone to several different health conditions. These include:
This condition can require surgery to keep the turning eyelid from injuring the eye ball.
This can cause lameness and arthritis.
This can cause lameness and arthritis.
Make sure you keep the ears clean and keep an eye on them.
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.
Don’t overfeed a Chow Chow as they are hard workers and big eaters. Feed them at least twice a day.
This eye disease can lead to blindness if not checked and treated.
These can be removed from an adolescent puppy.
Again, the Chow is susceptible to cancer.
Can lead to heart or kidney problems if left untreated.
Keep a close eye on your Chow Chow skin.
The Chow Chow was developed as working dog, but today’s version is more laid back and doesn’t need excessive exercise. Daily walks will suffice. They live very happily in the city if walked regularly. They are not really a competitive breed outside of obedience and confirmation. They are seldom seen in sports like agility or frisbee.
