History

irish staffordshire bull terrier - historyThe Staffordshire Bull Terrier comes from Staffordshire, England, but the Irish Staffie was later developed by Irish breeders so its origin is essentially Ireland. They were developed from bulldogs and different terrier breeds.

The dog was always used for bull baiting, but when this sport died out, the Irish breeders wanted to create a taller, leaner dog suited for dog fighting. When dog fighting was banned the breed became rare again, but today it has been restored and is essentially a popular companion pet.

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.

Characteristics

irish staffordshire bull terrier dog - characteristicsThe older Irish Staffie has always been an aggressive type dog used for fighting, but today the modern breed is capable of being a splendid, entertaining, amicable pet with an even temper. He is feisty for sure, being brave, fearless, loyal and loving with his human family members.

All it requires with this dog is to have a firm, loving upbringing, some training and socialization as well as good food and plenty of love and attention. Many dogs get labelled wrongly because of the humans that rear them the wrong way. When done correctly, the Irish Staffordshire Bull Terrier promises to be a wonderful, loving, loyal 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

irish staffordshire bull terrier puppies - health problemsThe Irish Staffordshire Bull Terrier, just like with any other dog, has a good chance of living a good number of years if he is fed properly. He can live to be anything up to between 10 and 16 years.

Say what you like, good nutrition and the lifestyle you provide for your Irish Staffie will determine how long he lives. An unhappy dog that has to beg for love and attention won't do well. Your Irish Staffie can live to a ripe age but he is still at risk for certain health problems.

Mastocytoma:

These mast cell tumors are graded according to their location in the skin. Certain dogs like Boxers and bulldogs are more susceptible to mast cell tumors than other breeds, and the Irish Staffie isn't immune either. Most times the tumor develops in an older dog, though young dogs have also been known to develop the tumor. These tumors can be inactive for a while and then experience some rapid growth with some redness and fluid build up. Immediate veterinary intervention will be required.

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:

irish staffordshire bull terrier dogs - caringThe Irish Staffie is an active dog, who is always game for anything. He will certainly need active owners who include him in all their activities. He has a lot of stamina and endurance and will want to join you on your walks, hikes and swimming. Ignoring his exercise needs can turn him into a restless, unhappy, frustrated, destructive dog.

Grooming:

Having a short, smooth coat means your Irish Staffie being a low maintenance dog. He does shed a bit so his coat will need to be brushed at least twice a week to get rid of all those loose hairs. Its always a good opportunity to check him for fleas and ticks too.

If the short coat gets too dirty, a wipe down with a damp cloth can keep the coat bright and shiny. Certainly avoid bathing him too often as this can aggravate the skin.

Check his nails and trim them if they get too long. Check his ears and teeth as these are all problem areas which can contribute to your dog becoming ill.

Diet:

Your Irish Staffie is such an energetic dog that he will need excellent food that promotes this energy. Whether you buy him the best commercially manufactured kibble, you want to also add in some home-made food such as cooked chicken, rice and vegetables as well as including some raw meat occasionally. The food you provide your Staffie with needs to be full of vitamins and minerals to avoid illness. Always make sure he has access to fresh, cool 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.
