The Pyrenean Mastiff originates from Spain, descending from ancient livestock guardian-type dogs.
They have always been used as guardians, looking out for livestock and warding off predators.
When you do research you find that there is little information on the exact origins of the dog. It was only in recent years that the dog was taken out of its native region and sent to the USA, but it isn’t recognized by the AKC.
The dog was however recognized by the FCI in 1982.
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.

This is a fairly healthy dog breed, particularly when you consider what a big dog he is. There are always some health concerns to watch for so that you can take steps to get your pet well again.
There is tartar build-up on the teeth and this can lead to infection of the gums and roots of the teeth. Rotting teeth can cause pain, but more worrisome they can cause damage to the heart and kidneys as well as the dog's joints. The vet or professional pet groomers can keep your pet’s teeth clean. They can advise you on how to take care of your large pet’s teeth.
Diseases such as rabies and parvo can be prevented by means of vaccine.
You can’t afford for a big dog like this to become obese. It’s a serious disease and can put pressure on your dog’s joints and also cause back pain and digestive disorders.
Your dog can be infected with all kinds of worms and bugs such as ticks d and fleas as well as mites. Some of these parasites can be transmitted to you. Your vet can talk about preventive medication.
Gastric Dilatation and Volvulus, commonly referred to as bloat often occurs in dogs with deep chests.
The stomach twists and fills with gas,and blood to the stomach is cut off. Left unattended to, your dog can die, sometimes within half an hour. His stomach is hard and swollen, requiring immediate veterinary attention.
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.
Have your pet spayed or neutered if you don’t want puppies. Spaying or neutering also decreases the likelihood of certain types of cancers.
Nothing but a top quality diet is good enough for your pet. Commercially manufactured dog foods are a convenient means to feed your pet, and there are some excellent brands.
Look out for the ones for extra large dogs and avoid the ones with low quality ingredients. The dry kibble you give your big pet can be made more tasty when you add some homemade food to it about twice a week.
Dogs thrive on simplicity, so boiled chicken, sweet potatoes, brown rice or pasta, carrots and spinach will be wonderful for him when you chop the food up and add it into the dry kibble. Its such a tasty, wholesome treat for your pet.
Some raw meat added in occasionally will contribute to your pet’s heath. Make sure he is never without a constant supply of fresh, cool water.
Brush his coat at least twice a week. Check inside his ears for redness which could indicate an ear infection.
He’s an intelligent pet with lots of energy, so you will need to keep his mind and body active by ensuring he enjoys walks every day. He isn’t a dog that requires running with you on your jogs or cycles.
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.

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.
