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 Shih Tzu is an Imperial Chinese breed developed by palace breeders hundreds of years ago with breed stock from the Tibetan lines. It is quite probable that the Shih Tzu was originally a cross between two Sino-Tibetan ancient dogs – the Pekingese and the Lhasa Apso. Based on their looks, the Shih Tzu means the lion dog, but they were really very pampered palace dogs living with the Chinese emperors and families. The emperors were always gifting the breeders who developed the most affectionate, gentle and beautiful Shih Tzus.
Until the 1930’s the Shih Tzu was not known to the world outside the emperor’s palace. Once the breed did come out from behind the palace walls, they were immediately popular. Much debate went on about how to refine the breed as clubs began to spring up in Peking and then in England. It was not until 1969 the Shih Tzu was recognized and entered in the AKC Stud Book.
While the original Shih Tzu might have been a mix between the Pekingese and the Lhasa Apso, today’s breed spread around the world after the second world war. In Europe in the 1930’s the breed was classified as Apsos. In 1935 the first Shih Tzu Club of Europe was formed, and the first standard was written, and the breed was categorized as the Shih Tzu.
Following World War II, soldiers brought the dogs to the States from Europe. By the 1950’s the breed was growing in popularity and the AKC recognized the breed in 1969 as members of the Toy Group. They are now recognized by all major kennel clubs throughout the western world. They are recognized by the Federation Cynoloqique Internationale in the Companion and Toy Group, among Tibetan breeds.
The Shih Tzu is a good watchdog, but it was bred to be a companion animal. It is a friendly, open breed that welcomes strangers. They are great with other animals and children as well as adults.
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.
This is a breed of lively, sturdy and alert little dogs with a beautiful double coat that is flowing and long. In its full glory the Shih Tzu coat is touching the floor all the way around the dog. The dog’s bearing is as royal as its history, arrogantly carrying his head high and his tail curving over his back.
The Shih Tzu is a solid, compact breed with weight and substance. They may be a small dog, but they are a strong one. They have large dark eyes with a short muzzle and fur covered drop ears. They are just a little longer than they are tall with a distinct underbite.
There are a few differences between the European or UK Kennel Club standard and the American Kennel Club AKC standard. As opposed to the UK standard the AKC standard states that:
• The hindquarters are muscular while the front are straight. They are balanced in that they are not too long or too short.
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.
2.Special talents – they were bred to be companion animals. They are friendly and loyal.
3.Adaptability Yes very much so. They can live in an apartment or on a farm. It doesn’t matter and they don’t need a yard.
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.
For many breeds that have the advantage of isolation like the Shih Tzu did with the emperors of China usually have very little genetic health issues. Most of the breed is indeed healthy but there are some issues.
• Brachycephalic airway obstructive syndrome due to the shape of their face and head causes them to have breathing issues. They cannot handle heat and they cannot swim. They can have an upper airway obstruction that makes it hard for them to breath. If this is bad enough, surgery may be required.
• Hypothyroidism – thyroid does not produce the hormones necessary for metabolism to work effectively. This can lead to weight gain, hair loss, lethargy and muscle loss. It can be treated effectively.
• Issues of the eyes include – cataracts, corneal dryness and inflammation, progressive retinal atrophy, improperly closing eyelids and retinal detachment.
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.
1.Feeding the puppy – this is a toy dog so don’t overfeed. They have a tendency to become obese. Calorie and weight level need to be calculated with any diet you feed. The diet should be high quality with plenty of protein made for toy dogs. Feed the puppy at least 3 times a day, maybe four in very small amounts, never more than ½ cup per day.
2.Feeding the adult - this is a toy dog so don’t overfeed. They have a tendency to become obese. Calorie and weight level need to be calculated with any diet you feed. The diet should be high quality with plenty of protein made for toy dogs. Feed the adult once or twice a day in larger amounts than the puppy but never more than ¾ of a cup per day.
3.Points for Good Health - most Shih Tzu’s are hardy with exceptionally good health.
This is a pampered, not high energy dog. However, she still needs playtime, which can be indoors and short walks outdoors every day.
