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 Pyrenean Shepherd hails from Spain where he has always been used to herd sheep. Some people believe he is a descendant of the French Catalan Sheepdog while others say from the Briard. Nobody is too sure.
He is actually the smallest of the French herding breeds. It is interesting to note that he still does this herding job today. It was in the 19th century that a few of these dogs left for America with shepherds who found work herding flocks in the American West.
These dogs were also used in World War 1 as messenger dogs.
It was during the 1970's and 1980's that breeding programs were started for the dog and The Pyrenean Shepherd Club of America was formed in 1987. The dog was also recognized in 2009 by the American Kennel Club.

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.
The Pyrenean Shepherd is such a jovial little dog that you just can’t imagine him ever being sick. When he is lethargic, you'll know there is something seriously wrong with him because he is always as bright as a button.
He can however get sick, and there are a few dog illnesses such as epilepsy, eye problems and hip dysplasia that can be very painful ad debilitating for such an energetic dog. You don’t have to be too concerned though, as he is a dog known to have minimal health issues.
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.
This will depend on the coat type. Both coat types will essentially require you brushing him twice a week.
The Pyr Shep’s activity levels are very high and this dog will require living with people who love outdoor activities. He’s the perfect companion for those camping trips or hikes. He is always ready to join you on your walks and will be ready and waiting to jump right in when he sees you with a ball or frisbee.
For all that energy, your Pyrenean Shepherd will be needing the best dog food there is. Food full of preservatives and colorants can be bad for your pet, detrimental to his health.
Good food full of vitamins and minerals will ensure your pet stands a good chance of living a long, healthy life. If you feed him commercially manufactured dog food, ensure its the best there is, with labeling on the packaging that tells you its for his age, his size and energy levels.
Consistency and simplicity is what your Pyrenean Shepherd wants, and home-made food can enhance his dry kibble. Boiled chicken, brown rice or pasta and spinach, sweet potatoes and carrots all chopped up and mixed into the dry kibble once or twice a week will ensure your pet’s eyes are continuously bright and alert and his tail constantly wagging.
Some raw meat added in occasionally will also go towards ensuring his good health. Always make sure he has access to fresh, cool water.
