History

fila brasileiro - historyHailing from Brazil, and known also as the Brazilian Mastiff, nobody seems to be too sure of the exact origins of the large Fila Brasileiro but it is believed to be a cross between the English Mastiff, the Bulldog and the Bloodhound.

Other theories are that the dog comes from a mix of Portuguese and Spanish dogs and that they were bred to guard livestock from predators. Breeds that have no doubt contributed to the modern Fila are the Bullenbeisser, the Bloodhound, Mastiff and Rafeiro do Alentejo. All these dogs have characteristics such as excellent working dog skills, herding instincts as well as courage and tenacity.

The official Brazilian breed standard of the Fila was developed in the 1960s and the Fila Brasileiro Club of America was formed in 1984.

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

fila brasileiro puppy - descriptionWith his huge head covered in loose skin much like that of a Blooohound, and a body resembling that of a Mastiff, the large heavily built Fila Brasileiro is a mastiff breed from Brazil. He stands at 60 to 75cm in height and he weighs roughly 55 to 80kg.

The ears of the Fila are large and droop down or are folded back, depending on his mood. The tail is long and slim. The coat of the dog is short and dense with the texture being quite smooth and soft. Colours of the coat can vary from solid fawn or black to red to brindle.

Temperament:

Perhaps the huge Fila wouldn’t be a good choice as a pet for the first-time inexperienced dog owner as he is a powerful, intelligent, self-assured, headstrong animal that will certainly need to have training and socialization if you want him as an obedient pet in your home.

He is a dog known for his courage and bravery. The Fila is loving and affectionate with his human family, being protective of them and not being too friendly with strangers. He isn't a particularly good pet choice with children in the home.

Some people, after buying a cute Fila puppy, put him out in the yard when he becomes large, and then they pretty much neglect him. This is cruel and irresponsible as he is a social, playful dog who wants to be part of his human family.

These dogs have some aggression in them and this makes them good watchdogs. They generally don’t show aggression towards their family but may snap at a stranger who tries to touch as he feels threatened.

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.

Characteristics

fila brasileiro dog - characteristicsThe Fila Brasileiro or Brazilian Mastiff is a powerful dog and it is believed that a large dog like this can be a danger to people if he isn’t trained and socialized.

He is therefore not recommended for first time dog owners or homes with small children. He is a dog that is particularly wary of strangers too.

When he has been properly socialized he can be loving, loyal and obedient because it is essentially how a dog is brought up as to how he turns out.

If you bring one of these big, beautiful dogs into your home, have him socialized as a puppy, treat him firmly, but kindly and you could have yourself an extraordinary 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.

Health Problems

fila brasileiro puppies - health problemsFilas are a dog breed who have a high rate of hip- and elbow dysplasia. This is a serious disease which can lead to lameness with your pet. Other orthopedic diseases with the breed include osteochondritis and luxating patella.

Also, as a deep-chested dog breed, your Fila also is at risk of getting the very serious gastrointestinal syndrome known as bloat. This is a common condition that can prove deadly for your pet. The Fila’s stomach will fill with gas, putting pressure on other organs and stopping blood flow to the heart and difficulty with breathing. Sometimes the stomach will twist. Get him to the vet immediately if you notice a swollen stomach, drooling or restless behaviour.

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 and Space:

fila brasileiro dogs - caringThe Filas size makes it important that he have a good amount of exercise if you want to maintain his health and happiness. He isn’t a dog suited to city life as he is too large and will irritate his owners when cooped up in a tiny space with them. He isn’t demanding when it comes to exercise and activities all the time, but he should still be exercised regularly as he is inclined to become lazy .

Grooming:

Moderate shedding. Regular brushing twice a week will be required. Check ears for infection and brush his teeth 2 or 3 times a week.

Diet:

Nothing is set in stone as to what to feed your Fila Brasileiro, but a large dog will require quality food with a good amount of protein and fat according to size, age and activity levels.

Because a large breed dog is prone to hip dysplasia, look out for ingredients such as chondroitin and gludosamine which are specifically good for joint health. Try and avoid commercially manufactured food with common allergens such as soy, corn and wheat, artifical flavors and fillers.

A source of cooked rice, chicken and vegetables as well as some raw meat will be excellent for your big pet. Make sure he is never deprived of fresh, cool drinking water.

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.
