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.

Based on the massive dog of Mesopotamia in 5000 BC, the American Molossus is the same dog recreated in the United States by and for the lovers of these giant dogs. The ancient Molossus was fierce to look at, massive in size, courageous and loyal. He was undaunted by any animal and stood up to any man attempting to hurt his master. When Rome fell the descendants of today’s Molossus were scattered and attempts to revive the breed have created carious large dogs. The American Molossus is the first true recreation that hits the mark.

The original Molossus was one of the most primitive of dogs, one of the earliest dogs that men domesticated. Their initials duties were the guarding of herds and homes against all enemies. They were incredibly loyal to their one master and stayed with him and protected him. These dogs also ate carrion and served the villages by eliminating animal carcasses. They could handle any other hunting animals such as wolves and large cats. This dog, although extinct was the ancestor of all the Mastiff-type dogs of today. The Molossus is said to be the ancestor of the St. Bernard, English Mastiff, Greater Swiss Mountain Dog, Bernese Mountain Dog, Newfoundland, Great Dane, Great Pyrenees, Rottweiler, Rottweiler and the Neapolitan Mastiff. Now these breeds have become the ancestry of the American Molossus.

According to Marcus Curtis, the founder of the new Molossus, the nearest relative of the American Molossus is the Neapolitan Mastiff. The Hines Bulldog, German Rottweiler, American Bandogge, and South African Boerboel together with the Neapolitan Mastiff were used to form the American Molossus. The goal of the founder was to make a great family pet and protector. It was specifically bred to be courageous, loyal and protective.

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.

This is a giant, massive dog in every way and this recently developed standard makes that very clear. The Molossus should be heavy bones, muscular with a lot of loose skin and wrinkles of all kinds, everywhere. He is an intimidating presence, with a massive square head, broad shoulders, height and mass. No, the American Molossus is not athletic, but he certainly is intimidating.

His head is massive in comparison to his body and it must be square. He has extensive wrinkles and pendulous lips and dewlap. The face is all folds of skin and wrinkles. Deep set eyes, drooping upper lids and lower lids as well as an intimidating expression. His brow is well developed with a marked frontal furrow. The nose is large, and the muzzle is about a third of the length of its head. It is short and broad. Everything about the head must be square. It’s neck and body are powerful and muscular. The chest is deep, wide and barrel like. The back is also powerful and muscular. The front legs are heavy and muscular while the hind legs are broad, strong, powerful and wide-stance. Do not remove the front dew claws. His tail is thick and wide then gradually tapers at the tip.

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.

Like all Mastiffs the American Molossus faces a variety of potential illnesses, some brought on by its size, some not.

Spondylosis

This could easily be a function of its massive size. It is a degenerative disease and can cause the dog to become lame. In many cases the vertebrae can fuse, or severe pain can result. This is mostly seen in older members of the breed.

Cystinuria

Male Molossus can contract this inherited metabolic disease primarily. It can be life threatening and very serious as it affects the kidney and the bladder.

Wobblers Syndrome

This is essentially Cervical Vertebral Instability (CVI) and is caused by the pressure of the nerves in the neck and cervical spinal cord. This compression can cause deformity, pain and abnormal stance/gait. IT has been attributed to the nutrition needs and rapid growth of the Mastiff breeds.

Like all giant Mastiff breeds the Molossus can have skin issues from the wrinkles, dysplasia in the joints which we will address below.

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.

Feeding

Remembering that this is a very, very large dog you need to be careful about nutrition and how fast your puppy will grow. American Molossus puppies need four meals a day until 12 weeks old. Then until they are 6 months old feed then 3 times a day. Finally, from 6-month-old puppy to adult – feed them twice in 24 hours.

At one year either feed them once or two small meals.

Many people feed their Molossus eggs, vegetables, fruit, and cottage cheese as ten 5 of the total for the day but avoid other table foods. The Molossus can become very picky about what he eats if you feed him too many table scraps.

Health issues

In addition to the health problems listed above, the American Molossus is also susceptible to: Ditichiasis – Eyelashes that are in the margin of the eyelids and can cause eye irritation. May require surgery to correct.

Cataract

Could cause blindness if not removed. Ectropian/Entropion: Eversion and inversion of eyelids which cause ocular irritation.

PRA or Progressive Retinal Atrophy

This is a degenerative disease which causes the dog to go blind. It is a disease the affects the retinal visual cells, first causing night blindness then day blindness. A DNA test is available for detecting PRA in all Mastiff breeds.

Dysplasia of the Elbow or/and the Hip

Common in large breeds and especially in giant breeds like the Molossus. Multiple forms and causes but all can cause pain and lameness.

Skin issues

Do to wrinkles and loose skin – check often for moisture and infections.

Panosteitis or Wandering Lameness

The is a problem based on a variety of possible causes. It happens when the puppy is between 6-16 months of age. Lameness occurs over time in one limb or in all. It can be intermittent and might be caused by diet, genetics, stress, autoimmune or metabolic issues or infection.

HOD or Hypertrophic Osteodystrophy

This issue is developmental as the dog’s toes turn either inward or outward, then as the condition advances the dog suffers fever, pain in all joints, lethargy and the inability to stand. This happens when the dog consumes too many calories for his activity level in the development times.

Exercise and games

The American Molossus is not a couch potato. He needs to be walked at least twice a day and loves to play fetch. He will be greatly benefited by obedience training. Do not overdo it with exercise but make sure they don’t just lay around.

Characteristics

The American Molossus is an intimidating massive giant bred for protection and guard duty. He is incredibly loyal to his family and courageous in his protection of them. They are guard dogs, not attack dogs. Their simple appearance is usually enough to frighten off anyone intending harm on their families. He is in reality a loving giant.
