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.

The Gran Mastín de Borinquen is also referred to as the Puerto Rican Mastiff or the Mastín Borincano and is actually native to Puerto Rico.

The dog seems to have originated long ago already during the 16th century. Its a dog that descends from a number of dogs, and the dog from these crosses became a huge, ferocious dog.

For centuries the Gran Mastin de Borinquen was used to protect the estates of the Spanish nobility. Today the breed is considered rare and it isn't recognized by any major kennel club as a standardized breed.

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.

The Gran Mastin de Borinquen is a large dog. He stands roughly between 56 and 71cm and weighs in at between 41 and 68kg.

He is well muscled with a large head and short floppy ears but until recently the ears have always been cropped. The nose is black, the eyes dark brown and small and he has an alert, intelligent look to him.

These days the tail is kept long and it is held low. The coat is short in length and harsh with the colour being fawn, black, cream or brindle. You'll also find some small inclusions of white on the coat.

Temperament:

Loyal and protective, the Gran Mastin de Borinquen forms a strong bond with his master, becoming aggressive with any stranger who comes too close to his owner.Its a dog that has been taught to be aggressive so he isn't the best pet to choose if you have children in the home. He isn't the best dog either for first time dog owners, particularly if the person isn't a strong, firm person around him, showing who is boss.

However there are people who have had their pet trained and socialized and who claim he makes a wonderful family pet. The way a dog is brought up can play a large role in the way he turns out.

Train and socialize your Gran Mastin de Borinquen because he is inclined to be strong-willed and for a large, aggressive type of dog, you want him to be obeying you.

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.

Noble, courageous and loyal, a trained, socialized Gran Mastin de Borinquen who has learned simple commands such as sit, down, come, stay, lie-down and heel will be an absolute pleasure to have around and be a well behaved, obedient companion for you.

Your Gran Masin is a dignified, loving animal, but because of his size and his origin, bred to be aggressive, he isn’t looked upon as the first choice when you’ve got small children in the home. With the right owner – fair, firm and loving - he makes a splendid pet.

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.

Your Gran Mastin de Borinquen can get to 12 years of age with good care. Mastiff-type dogs like this can be prone to eye problems as well as having to tackle joint problems such as hip dysplasia.

Other issues that can appear in this breed, but are unlikely be cancer, bloat, hypothyroidism and von Willebrand’s Disease which is a bleeding disorder.

Remember to do daily inspections of your Gran Mastin de Borinquen for fleas and ticks, particularly during the Summer month. Toxins introduced into the body by a tick bite for instance can make your pet seriously ill so that veterinary intervention is required.

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:

The Gran Mastin de Borinquen, with his short coat, is a relatively low maintenance breed. Brush him at least twice a week to keep the coat free of loose hairs. Other grooming requirements are keeping his ears clean and dry. You can ask about alcohol wipes at your local pet shop to use in his ears. Check the nails too and remember to brush his teeth a couple of times a week to avoid dental decay.

Exercise:

You won't find the Gran Mastin de Borinquen being a particularly high energy dog but he also isn't a couch potato. If you enjoy a walk every day for your own good health, include him in these walks and give him a game of ball every now and again.

Diet:

This Mastiff -type dog is large, and they tend to be fairly lazy, not using up great deals of energy. Young dogs however use up more energy and will require a diet with good quality protein.

Dogs that have been spayed or neutered as well as senior dogs will require less calories. If you buy commercially manufactured food, check the labels carefully and buy high quality food for a large breed.

Don't just feed your Gran Mastin kibble everyday but alternate it sometimes, mixing in some raw meat into his kibble or mixing in some cooked chicken, rice and vegetables.
