History

great pyrenees - historyThe Great Pyrenees could be from Spain or France because the dog hails from the Pyrenees Mountains, which spans both France and Spain.

The dog was used to defend flocks from predators but its lineage goes a long way back, thousands of years in fact. It is thought that they only arrived in Europe about 5,000 years ago. The dog was adopted into the court of Louis the XIV as a royal dog.

During the mid 1600s, the dog's numbers dwindled but the French developed kennel clubs where the dog could be bred and its numbers restored. It was in 1933 that the Great Pyrenees received American Kennel Club recognition.

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

great pyrenees puppy - descriptionThis is a beautiful dog, noticeable by the essentially white coat and his overall size, standing at 70 to 82cm and weighing between 40 to 54 kg.

The double coat is medium to long, coarse and straight or wavy and and it can be solid white, cream or white with patches of light tan or grey.

The nose is black, the eyes brown, the ears of medium length and floppy and the tail long and plumed.

Temperament:

The Great Pyrenees is an intelligent, strong willed dog with a mind of his own so he will be able to be trained and socialized successfully.

His huge size will require that he be trained because when he is indoors he can knock things over and he must be able to respond to you telling him to lie down.

As a large dog, he isn’t suited for tiny homes, as he requires lots of space even though he doesn’t require a lot of exercise. Not only that, he takes his watchdog duties seriously and he is inclined to bark a lot, and in a small place, you’ll be getting constant complaints from the neighbors.

When trained and socialized, your big dog is social, active and loving. He gets on well with children, the elderly and with pets in the home. He isn’t that overly active and will happily make himself at home on your couch and bed.

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

great pyrenees dog - characteristicsThe Great Pyrenees is such a calm, independent, serious, well-mannered dog who loves to be around his human family and to please them. He is gentle and knows how to behave well around children, the elderly as well as with any pets in the home.

He makes a wonderful companion and although he loves indoor life as much as outdoor life, he is much happier settling into life in the country or the suburbs as opposed to life in the city and a tiny property.

Give your big white coated pet all the love he thrives on, and you'll enjoy a wonderful relationship with this large, amicable dog.

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

great pyrenees puppies - health problemsYour Great Pyrenees is a big dog with an average lifespan of 10 to 12 years. His large size means you will need to look out for typical 'big dog' ailments such as hip dysplasia.

This problem can cause your pet to be in pain and he can also become lame, battling to walk and play and battling to get up after lying down.

Also, look out for bone cancer with your pet and as mentioned previously, bloat, which is a life threatening disease where the stomach of the dog swells up.

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:

great pyrenees dogs - caringYour Great Pyrenees isn't going to be a dog leaping around you demanding a game or walk like what you get from some energetic dogs. He certainly doesn't require strenuous exercise but will require a nice, brisk walk every day. Give him some ball or rope games too. He's territorial and likes large grounds to walk around and guard and this constant guarding is a good form of exercise too.

Grooming:

With two layers, the coat of the Great Pyrenees will need to be brushed twice a week to prevent burrs attaching to the fur and to prevent it from matting, It also gets rid of loose hair during shedding.

He tends to drool so it's handy keeping a damp cloth close by just to give his face area a wipe down. Your dog's ears will need to be cleaned with special ear-cleaning lotion and his nails will also need to be trimmed.

Socialization and Training:

Socialize your Great Pyrenees with other dogs and people from a young age. Without proper socialization, this breed can become territorial and possessive of his family, which could lead to aggression. He bonds with his family but tends to be wary of strangers.

Diet:

It is far better to feed your Great Pyrenees smaller meals throughout the day as opposed to 2 large meals a day. A large dog like him can develop bloat from gulping down a large amount of food too quickly.

If you feed your Great Pyrenees commercially manufactured food, make sure it is high in omega 3 and 6 to keep his thick white coat luxurious.

Your dog will need a dog food targeted at a large breed. Remember to include some raw meat as well as cooked chicken, vegetables and brown rice into his kibble and always ensure fresh, cool water is available.

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.
