With the Mastiff breeds, the rarest and the smallest is the Nebolish Mastiff. Bred to be more agile than the giant mastiffs, the Nebolish was developed in Canada. They were developed by crossing several breeds, such as the English Mastiff, Neapolitan Mastiff, Dogue de Bordeux, Bull Terrier, Bullmastiff, Boxer, St. Bernard, and Deutsche Dogge. Perhaps there was some Great Dane as well. It was also hoped that they would have better health than the rest of the Mastiff breeds.
There are also those who believe the Nebolish Mastiff is not a Canadian crossbreed but rather the re-creation of the giant dogs that lived with the soldiers of Alexander the Great. Still others believe the breed is still being developed and no standard is yet true. They believe the dog is a hybrid. No one knows the exact breeding lines today and not many are breeding the Nebolish today. Thus, the dog is extremely rare.
Only the American Breeder Association (ABA), the Canada Molosser Association (CMA) and the Dog Registry of America Inc. (DRA) recognize the Nebolish Mastiff as a separate breed.
These dogs are courageous, loyal and dignified like all Mastiffs. They are protective of their families or their flocks. They are loving, intelligent and even-tempered. They are known to be great with kids since they are patient and calm – easy to train.
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 Nebolish Mastiff is very much like all other mastiffs with the exception of height and weight. He has a large head, long legs, strong neck, oval shaped paws, wide chest and large bones. He has solid muscles, large ears and a wide snout. They usually weigh anywhere between 43 and 82 kg. They tend not to slobber like the other mastiff breeds as a result of their breeding. They have a black mask and tail may or may not be docked.
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.
Yes, they are very good with children.
Agility and swimming
No – they don’t do well with apartments and small spaces. They need a large fenced in yard.
High but can be stubborn
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.
Bred to be much healthier than other mastiff breeds, the Nebolish has very few health concerns. They live twice as long as most other Mastiff and giant breeds at up to 14 years. The most often reported health issue is:
bloat – where the intestines and stomach organs are twisted or distended. Bloat can be deadly so don’t hesitate on treatment. Avoid it by not overfeeding after or before exercise.
Test for Hip dysplasia as it can cause lameness or arthritis.
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.
Don’t overfeed and don’t feed too much protein in the first year. Feed 1-2 cups in two meals.
bloat – Tendency to become obese so don’t over feed. About 2-3 cups in 2 meals per day.
agility and flexibility
This intelligent breed actually enjoys training, toys and all kinds of mentally stimulating puzzles. They love water and are very good swimmers. They need an average amount of exercise - a couple walks per day. Need a large fenced yard. They make great therapy dogs and play catch.
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.
