History

english mastiffThroughout most of history there have been images created by people of very large, sturdy dogs that they shared their space with. The English Mastiff can trace some part of her ancestry to these same dogs. This breed is thought to have come from the stock of ancient breeds such as the Alpine Mastiff, Pugnaces Britanniae and Alaunt. The Mastiff in general has then become a main descendent of many other breeds of dogs since the 1880’s. The images of these types of dogs goes back to the 5th and 6th century.

There is no genetic evidence linking these dogs to the modern Mastiffs and the English Mastiff, but the resemblance is obvious. There is anecdotal evidence that these Mastiff type dogs were exported from England – the English Mastiff – to Greece to hunt game but were also used as war dogs by the Celts. The Alaunt was probably used the Normans and bred by the Alans. Writings and images throughout these times depicted a dog that looked very much like today’s English Mastiff. Some speculate that the English Mastiff came to the United States of the Mayflower.

There was a decline in the English Mastiff in its homeland in the 1800’s following the Cruelty to Animals Act of 1835 which prohibited owners and trainers from baiting animals. Then in the 19th century, prior to the first World War, systematic breeding programs began with J.W. Thompson. His first English Mastiff was a female named Dorah. Dorah’s ancestors included dogs from Thompson’s Grandfather. Captain John Garnier of the Royal Engineers also had dogs that contributed to the development of the English Mastiff.

During this time some breeders got away from pure type and began to breed for other factors. In the late 1800’s, Edgar Hanbury and Mark Hanbury Beaufoy began restoring the breed to its original soundness. One of their dogs was exported to the US were breeding to soundness continued until the First World War reduced the number of English Mastiffs around the world. By the time the war ended there were no English Mastiffs outside of England.

There was a dog in Canada named Beowulf and direct descendent of imports from Britain, who came to the States after the war and began to re-establish the breed on this continent and registered with the American Kennel Club. Yet as of 1945, the contribution from North

Breeding was stopped again for World War II and started again after the war. Many of these puppies died of distemper. Only one female had pups that were able to grow up into adults. North America sent dogs to England at this time and all of the Mastiffs from that time, could be traced back to Nydia and the 14 North American Mastiffs. Since then the breed has been restored slowly in Europe, North America and everywhere in the world.

The English Mastiff is known by his massive head with a black mask and comes in a wide variety of colors. He is also known as a gentle giant because of his personality and the love he has for his people.

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.

Description

english mastiff puppyThe English Mastiff is a giant dog with a broad head and body. In terms of mass it is the worlds largest dog, just a little bigger that the Saint Bernard. The Great Dane and the Irish Wolfhound are 6 inches taller but do not carry the weight and bulk of the Mastiff. Mostly square in his body and his head with a massive chest and wide set forelegs. The head is square and very large. No matter the color of the coat, the face should have a black mask like the St. Bernard. His eyes and nose are also dark.

american mastiff puppyThis 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.

Health Problems

english mastiff dogBeing a massive dog can take its toll on the body’s development and that is certainly true of the English Mastiff. A lot of running is not recommended in the early life of the dog – preferable for the first two years. This could damage the joint’s growth plates and cause him a lot of problems in later years. Too much exercise in this massive dog can hurt him but so can, not enough exercise.

Some of the health issues other than this that the English Mastiff is prone to include:

  1. Calluses –
  2. On their paws. Must be taken care of before infection sets in.
  3. Arthritis

A large dog like the English Mastiff is always prone to pain from arthritic joints. See your vet about pain medication.

Hygroma

A spot under the skin that is swollen and filled with fluid. Can be treated. It is not an infection or contagious.

Hip Dysplasia

Can result in lameness and arthritis.

american mastiff dogAmerican 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.

Caring The Pet

english mastiff puppiesThis is an enormous dog that grows quickly. It is important to feed them properly as they grow. If he doesn’t get what he needs as a puppy you will not be able to make it up to him later on.

Feeding the puppy

The English Mastiff puppy needs good nutrition for growing properly.

From 12-16 weeks of age feed him 3-4 cups a day of a high protein, high quality dry food. Break this up into 3-4 meals.

From 4 -6 months of age feed him 8-10 cups a day of a high protein, high quality dry food. Break this up into 2-3 meals.

From 6-18 months of age feed him 8-12 cups a day of a high protein, high quality, dry food. Break this up into 2-3 meals.

Feeding the adult

The English Mastiff is still growing from a year to 18 months. Starting at 18 months feed him 10-12 cups a day of high protein, high quality dry food. Break this up into 2 meals.

As your Mastiff ages, cut down on the protein and feed a dry food appropriate for his age.

Points for Good Health

The English Mastiff is a very large dog that should not be allowed to get obese since he is prone to dysplasia. He needs protein throughout puppyhood and until he is about 8-10.

Games and Exercises

This is a couch potato if you let him be. Make sure he gets at least one long walk per day or he will tend to gain weight. Play with them off leash about an hour every day.

american mastiff puppiesGiant 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.

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.

They love to please their people and being highly intelligent they learn fast.
