An ancient breed, the Neapolitan Mastiffs are massive dogs with a history of protecting their family and their property. The breed has deep rooted protective instincts and they are very frightening in appearance. The Neapolitan is of the Molosser group of dogs, all of whom probably came from the same line. It is known that all the mastiffs in Europe are descendants of the Tibetan Mastiff. The Tibetan Mastiff is considered the most ancient of all canines.
The Asian Mastiffs came from India to Greece around 300 BC with Alexander the Great. Then the breed was brought to the Romans by the Greeks and then introduced them in their circus in fights. Another possibility is that around 500 BC the mastiffs came to Britain from the Phoenicians. Either way the Roman Molossus is the ancestor of the Neapolitan Mastiff.
The Romans crossed the breed with the English Mastiff around 55 BC and developed a premiere war dog that was called a Mastini.
The breed eventually became extinct in Europe with the exception of Campania. The breed was recognized in 1946 with the standard accepted in 1949. However, it is believed that the Neapolitan Mastiff has been continuously present in Campania for over two thousand years. The breed was initially developed as war dogs and for the Roman coliseum spectacles.
In 1946 Dr. Piero Scanziani established a program to breed them in Italy. He wrote the breed standard in 1949.
Today the Neo is a farm dog, an army dog, a police dog and a guard dog. They were shown in Italy for the first time in 1946 but only in 2004 was the breed recognized by the American Kennel Club (AKC). It was 1973 when the Neapolitan Mastiff Club of America was born and 1996 when the standard was approved by the AKC. They are still a rare breed in the United States.
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.

The Neapolitan Mastiff is prone to many of the same issues as any massive, extra large breed. The most common of these is Cherry Eye.
Like all Mastiffs the American Molossus faces a variety of potential illnesses, some brought on by its size, some not.
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.
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.
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.
Neapolitans grow fast and so don’t overfeed when they are young. Lower protein and higher fat content.
Don’t overfeed the adult as they can become obese.
This big hearty breed needs exercise but not too much. They overheat easily. The puppy will push himself, so you have to make sure he doesn’t over do it. No tug of war games. They need a long walk twice every day.
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.
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.
Could cause blindness if not removed. Ectropian/Entropion: Eversion and inversion of eyelids which cause ocular irritation.
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.
Common in large breeds and especially in giant breeds like the Molossus. Multiple forms and causes but all can cause pain and lameness.
Do to wrinkles and loose skin – check often for moisture and infections.
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.
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.
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.
