History

The Molossus has always been a popular dog and they have been around since ancient times. Mastiff type dogs are termed as Molossus.

Of course, when looking at the origin of the dog, there are many unsubstantiated claims about it. It has always been believed that the Molossus was a Mastiff-type dog, ferocious in battle. The Romans were dog breeders and recognized that the Molossus was a talented dog – good at guarding and herding.

Over the centuries the dog has changed but it is believed it was a Mastiff-type dog with a number of other breeds included in its origins such as the Rottweiler, Pug, Bulldog, Great Dane, Alano Espanol and Saint Bernard.

The Molossus isn’t a dog breed itself but rather a category that other dogs belong to. Today there are Molosser clubs and Molosser shows around the world.

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

This Ancient dog breed from Greece has different descriptions of what it really looked like. It seems to have always been large to medium sized dog standing in the region of 50 to 76cm in height and weighing anything from 25 to 55kg.

The coat is mostly short and smooth and can be in a host of different colors. They are large boned dogs, solidly built with medium sized floppy ears, a short, thick neck, short, broad muzzle and a long tail which was later docked.

Molossers typically have heavy bones, pendant ears, and a relatively short and well-muscled neck, with a short, broad muzzle. These Molossers have always been used for a variety of jobs where strength, perseverance, speed and braveness are required. They have been used as rescue- and guard dogs, protecting livestock from predators.

Temperament:

The Molossus dogs all have the same kind of characteristics which have been bred into them. From their working days, they are known for their tremendous courage, taking on wild animals to protect their livestock.

They are territorial, wanting to protect their human family and home from intruders.They have also been bred to be loyal, loving family pets, and being highly affectionate, they want to be involved in the activities of the family.

This breed is gentle and loving, social and active and gets on well with other pets in the home as well as with children. They’re intelligent dogs and will need to be trained and socialized to ensure they are obedient and amicable with visitors to the home.

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

These large dogs are particularly prone to health issues such as hip dysplasia, a genetic condition. A poor diet as well as environmental factors can contribute towards the disease too as well as rapid weight gain and obesity.

This disease develops because the dog’s hip joints haven’t developed properly. The hips then partially dislocate, and the dog has pain and battles to get around. If your dog shows signs of hip dysplasia, he will need to get to the vet to do a physical exam and come up with a treatment- and management program.

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

Exercise:

These dogs were bred to be working dogs and they have always spent their time outdoors performing a guarding or rescue role. Today they require a lot of exercise – walks and ball games – as they are dogs with a lot of energy.

Diet:

Essentially a large breed, the Molossus will need a commercially manufactured food of high quality if you opt to make use of the convenience of these foods.

Make sure to choose one manufactured for large breeds and which is free of a host of bad ingredients such as corn, soy, wheat, dairy, artificial colors, sweeteners and preservatives.

You want dog food which is high in protein and fat. Try and include some home-cooked food such as boiled chicken, brown rice, pasta and vegetables. An ingredient to look out for in your dog’s food is omega-3 fatty acid to help keep the skin and coat shiny and healthy. Puppies particularly benefit from DHA, or Docosahexaenoic acid, a form of omega-3 fatty acid that is good for brain development.

Grooming:

Brushing the dog’s coat twice a week will be necessary to remove loose hairs, especially during the shedding period. When you brush him, check for ticks and fleas and speak to your vet about flea treatment if necessary. Ears and eyes should be checked and cleaned regularly.

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 Molossus, contrary to what many people think, isn’t a vicious dog, but rather a good natured dog that makes a wonderful family pet.

These dogs are known also for being hard working dogs with characteristics of bravery. They are dogs who may look fairly tough, but they are actually gentle, calm and sensitive. It’s a bad upbringing from the owners that gives any dog bad characteristics.

Train your Molossus, have him socialized and be a responsible and loving dog owner, and these dogs promise to make you a splendid family pet.

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. He is intelligent and stable with a strong desire to please his owner. He is a calm yet vigilant presence in the home.

Because the Molossus is so large, it is recommended that the puppy be socialized and trained professionally. It takes a strong owner to handle this breed. They need to know the rules and have the rules consistently applied. The owner must be the pack leader.
