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.

bullmastiffThe Old English Mastiff as well as the Bulldog are the breeds behind the Bull Mastiff. The Bullmastiff was originally developed in England around the 1860’s. Gamekeepers in England wanted a large, brave, robust dog which could help with keeping poachers away from their large estates which kept game.

As these large estates dwindled, so did the need for the services of the Bullmastiff and later they were simply bred to be family companions. As more Old English Mastiffs were bred, the dog became lighter, so that light tan or fawn became the preferred color.

The breed was officially recognized by the English Kennel Club in 1924, and the American Kennel Club in 1933.

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. 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.

bullmastiff puppy - descriptionBullmastiffs are large, brachycephalic dogs, and heights are between 61 and 68cm and the dog weight anything between 41 – 59kg. While it isn’t particularly tall, the dog is thickly set with a deep chest and strong, muscular legs. The Bull Mastiff has a powerful build and plenty of strength with an imposing look on his face. He is a powerful, active breed with a short coat which is also weather resistant and can be any shade of fawn, red or brindle.

The dog has a black muzzle and the skull is large and square. The ears are set high and are short and floppy. The tail was once docked, giving the dog an even more distinctive, powerful appearance, but these days, due to regulations, the tail is left long.

Temperament

The Bullmastiff is a loyal, devoted, fearless, protective dog. When he belongs to a human family, he becomes a companion but a fierce protector too, being a territorial dog. They love being with their family and can be good with children too, and even other pets, but proper training and socialization will be important. They aren’t aggressive around strangers, though he does make a wonderful guard dog.

He is intelligent and stubborn and if you don’t want him becoming destructive, even though he is a low-energy dog, you will need to exercise him and walk him every day.

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. 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.

bullmastiff dog - characteristicsContrary to his formidable looks, the Bullmastiff is a gentle, affectionate pet when he has been properly socialized. He is a great pet for families and will guard them with his life. He is loyal and devoted but can be somewhat aloof, particularly with strangers.

He isn’t a highly energetic dog and he is more or less low maintenance and easy-going. Feed him correctly, give him a nice, warm sleeping spot to call his own and give him attention like he deserves as a family member. The Bullmastiff will reward you by being a solid and devoted companion.

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.

bullmastiff puppies - health problemsThe Bullmastiff is a generally healthy breed, but even so, the breed is known for having to contend with certain health issues. He doesn’t have a particularly long life span either and can live to be about 10, ll or 12 years of age. Some of the more common illnesses to look out for include -

Hip Dysplasia:

This is a condition where the thighbone doesn’t fit properly into the hip joint. The troublesome part is that it can lead to arthritis, pain and lameness for your pet.

Bloat:

This is a worrisome, life-threatening condition for a dog, particularly for large, deep-chested dogs such as your Bullmastiff. Instead of feeding your Mastiff one large meal, it is recommended to feed him 2 smaller meals. Bloat occurs when the stomach is distended with gas or air and twists, restricting the normal return of blood to the heart.

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.

Grooming for Health and Happiness

bullmastiff dogs - caringThe Bullmastiff has a short dense coat which is looked upon as low-maintenance. He will require a brushing twice a week, being a light to average shedder. He is a dog that tends to drool quite a bit so you may need to wipe away slobber from time to time. Because his face has wrinkles, check the creases to ensure they remain free of dirt and food particles to ward off infection.

Check his ears at the same time, brush his teeth at least twice a week with special dog-toothpaste and brush and keep the nails trimmed.

Diet:

Your large Bullmastiff will require high-quality commercial dog food but he will also need some home-made food in between such as rice, vegetables and meat. He is a large dog and will have to get an intake of raw meat too. Dogs denied raw meat can end up with skin problems as well as other health issues.It is better to feel your Bullmastiff smaller meals than to give him one large meal which he scoffs down quickly. Smaller meals will help prevent the most dangerous illness known as Bloat.

Ensure he has a steady supply of fresh, cool water.
