PetzloverAmerican Molossus is originated from United States but Thai Ridgeback is originated from Thailand. Both American Molossus and Thai Ridgeback are having almost same height. American Molossus may weigh 14 kg / 31 pounds more than Thai Ridgeback. Both American Molossus and Thai Ridgeback has almost same life span. Both American Molossus and Thai Ridgeback has almost same litter size. Both American Molossus and Thai Ridgeback requires Moderate Maintenance.
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.
Until recently the Thai Ridgeback was not known outside of its native land. However, after being recently recognized as a standard breed, the dogs are getting some notice from the western world. They are one of three known ridgeback breeds with the ridge running the opposite direction of the rest of her fur. The other breeds with this characteristic are the better known Rhodesian Ridgeback and the even lesser known Phu Quoc Ridgeback.
The Thai Ridgeback is believed to have originated in eastern Thailand but there is no documentation of their actual history. The breed is thought to be descended from the Funan Ridgeback based on a genetic hypothesis. It is thought that the same Funan Ridgeback is an ancestor od the Phu Quoc Dog. This Funan Ridgeback lived over a century ago. Along with the Rhodesian Ridgeback, all have a common ridgebearing ancestor.
It is still unknown where the original ridge came from but it has been shown that all of the ridgeback dogs have the same genetic mutation and even though the Rhodisian is from Africa, there is not a parallel mutation. The Thai Ridgeback is an active, energetic, tough dog. He is loyal, intelligent, and has great jumping ability.
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.
The breed is medium in size and muscular in body. They have a wedge shaped head, a short coat that is smooth and pricked, triangular ears. The ridge on his back is pronounced as the hair grows away from the rest of the coat from the hips to the withers. Puppies can be born with or without the ridge. They are extremely agile. With what is often called a sword tail being carried up, the Ridgeback has wrinkles on his forehead, a black tongue or the tongue has black marks, and almond shaped eyes.
The coat sheds minimally and is dense, while the eyes are usually brown – in blue dogs they can be amber. The color of the coat is fawn, red, black or blue with a black mask on the reds. There are 8 different ridge patterns: Feather, violin, saddleback, needle, arrow, bowling pin, lute, and leaf. The broader the ridge the better the dog is considered for show.
There are two epistatic genes that determine the ridge and its size. The more genes of this type the individual dog has, the broader the ridge will be. There must be a dominant gene for the ridge to appear at all.
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.
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.
With such a mysterious origin, there are not a lot of documented episodes of genetic illness as the breed has been isolated in Thailand and natural selection has driven reproduction. There are only a few issues that they are genetically predisposed to. These include:
• Dermoid Sinus – this is a genetic skin condition known as pilonidal sinus as well. This is a defect in the neural tube and the sinus might be removed. If the sinus is wrapped around the spinal cord and cannot be removed it can be tied off.
• Bloat – can be terminal if not treated as soon as possible. Bloat is a distension of the stomach and intestines which can twist and tangle, killing the dog almost immediately without veterinary attention.
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 - Don’t over feed the puppy as they are inclined to become obese. Feed a high quality protein rich puppy for medium breeds. Feed in 3-4 smaller meals per day. As he grows be aware of bloat possibilities.
2. Feeding the adult dog - The risk of bloat is even greater in the adult and so is the risk of obesity. Don’t feed large meals and don’t feed before or after strenuous exercise. Feed in 2 smaller meals per day.
4. Games and Exercises – Energetic and needs serious exercise. She loves to swim, retrieve, hike, hunt, and catch frisbees. Likes search and rescue and guard dog work.
