History

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.

st john s water dogThe breed known as the St. John’s water dog is an extinct landrace breed. They were domestic dogs found in Newfoundland and at times were called the lesser Newfoundland. There is not much information available about the other breeds that went into its development. Hypothetically it is believed they are a mix of the Irish, Old English and Portuguese dogs bred to work.

It is also thought that other breeds in their family tree, descending from them, include the Golden Retriever, the Flat-Coated Retriever, the Chesapeake Bay Retriever, the Labrador and the Curly-Coated Retriever. The Newfoundland is also related to the St. Johns Water Dog through the line of Rafeirio do Alenteios that Portuguese fisherman brought to the island.

The breed was exported to England in the 19th century and early 20th. There the breeds of retrievers were developed. In Canada during this time frame restrictions were placed on dog ownership in order to encourage people to raise sheep. At the same time England imposed a long quarantine on all animals coming into the country in order to get rid of rabies. These two factors contributed greatly to the extinction of the breed. It seems the last two dogs were seen in a remote area in the 1980’s. All attempts to save the breed failed.

Description

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.

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.

Health Problems

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.

st john s water dog puppies - health problemsThere is no documented history of any genetic or hereditary illnesses in the breed. However, it seems rational to believe they suffered from ailments similar to Labradors and newfoundland though they are smaller dogs.

No history like Labs and Newfoundlands .

  • Hip and elbow dysplasia – can cause lameness and arthritis.
  • PRA – progressive retinal atrophy – can cause blindness.
  • Cancer – in their later years.
  • Infectious diseases – not as serious as prior to vaccinations.
  • Myopathy hereditary – affects the muscles.
  • Ear infections.

Caring The Pet

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.
