MyDogBreedsBoth Kyi-Leo and American Molossus are originated from United States. Kyi-Leo may grow 36 cm / 14 inches shorter than American Molossus. Kyi-Leo may weigh 42 kg / 92 pounds lesser than American Molossus. Both Kyi-Leo and American Molossus has almost same life span. Both Kyi-Leo and American Molossus has same litter size. Both Kyi-Leo and American Molossus requires Moderate maintenance.
The Kyi-Leo first came about in the 1950s in San Francisco, USA, with the crossing of two dog breeds – the Lhasa Apso and the Maltese.
Because this is a mixed-breed dog, it isn’t recognized by the American Kennel Club, but it is recognized by some of the other dog associations such as the American Rare Breed Association or ARBA as it is known. Today the dog is looked upon as a designer breed.
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 Kyi-Leo is a small dog standing at 20 – 30cm in height and weighing in the region of 4 – 6kg.
He has a long, silky coat which is essentially black and white or grey/silver and white or even gold and white. He has frail legs which can become injured or broken in vigorous rough and tumble games.
You can certainly describe the Kyi-Leo as a sweet, quiet, non-aggessive playful dog, and for anyone who wants a splendid pet and companion, this dog makes a great family pet and he won’t cost you an arm and a leg to feed either.
He also has an acute sense of hearing and this turns him into an excellent ‘alarm’ watch-dog. It is also a dog, that while he will love to join you on a walk, he isn’t a dog that is going to demand a lot of exercise.
He responds well to his human family, is easy-going and gentle, tending to be cautious around strangers. You can trust him to be an awesome playmate for children. In this instance, it’s the children who should be warned when playing with a dog like this as, because of his fragile build, he could easily be injured by children who haven’t been taught to respect animals.
Even though he is such an amicable pet, it will still be of benefit to you and him to have him trained and socialized. Then he responds well to basic commands such as sit, stay and lie-down.
Dogs who spend time with their family, pick up on the ‘culture’ of the family and they learn how to behave. Dogs who are left on their own and never socialized can become nervous and aggressive towards people as they never got to learn how to behave – they weren’t socialized.
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 Kyi-Leo is everything you want in a family companion – active, playful, loving, gentle, happy and balanced.
He loves his human family but tends to be a little bit wary around strangers, gradually warming to them.
He may be small, but he is robust and alert, and he is also capable of making you a good watchdog.
The Kyi-Leo is an all-round great little pet to have.
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.
Your Kyi-Leo is such a feisty, robust little dog who is not likely to cost you much in terms of health care. With his frail legs, it is a good thing to know that you need to be careful with him in terms of back-and joint problems.
There are actually knee joint issues which are fairly common in small dogs, one of which is patellar luxation.
This is where the kneecap pops out of the thighbone, causing the dog to skip or hop. Some joint issues are genetic and may require surgery. Make sure to keep your pet’s weight under control to remove additional stress on the joints.
This is another dog illness you want to be careful with. Acute pancreatitis -inflammation - is when the condition comes on suddenly while chronic pancreatitis is when pancreatitis occurs over a period of time.
With acute pancreatitis in dogs you’ll see symptoms such as vomiting, abdominal pain, tremors and reluctance to eat. Pancreatitis can be brought on by too much fat, especially rancid fat, some anti-biotics, a low protein diet or a sickness such as diabetes.
If you suspect pancreatitis in your dog, get him as quickly as possible to the vet.
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 Kyi-Leo doesn’t require vigorous exercising. One walk a day will keep them happy. There are pet owners who believe dogs can be permanently outside dogs where they can do their own exercise.
Everybody who knows dogs, knows they are social creatures who will simply lie at your backdoor just waiting for some response from their beloved human family. Every dog, regardless of breed or size, needs exercise and interaction with their humans every day.
Dogs left alone in the yard day after day are loney, frustrated and bored, and when they start digging or barking, irresponsible owners will ill treat them. These kind of people should never own a dog.
The Kyi-Leo has a sensitive stomach so he’ll need good quality food to avoid digestive problems. Ideally home-cooked food such as softly boiled chicken, brown rice and raw or cooked vegetables added into top quality kibble is the preferred diet.
Fresh, cool water needs to be constantly available.
Brush the long, silky coat at least twice a week to ensure it remains free of knotting. Brushing keeps the coat shiny too.
As a long eared dog, ears should be checked and cleaned regularly too. Air doesn’t reach the inside of their ears and the warm dampness in the ears are a breeding place for infection.
Nails should also be trimmed when they become long because left uncut they can hook onto things causing injury ad pain.
Small dogs are more prone to tartar formation and loss of teeth. You’ll notice that something isn’t right because your lively little dog will be lethargic, he may not want to eat his food and his face may be swollen. When you suspect dental problems, get him to the vet.
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.
