History

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.

australian collie - historyThe Koolie, as a breed we know today, originates from Australia. But, before they were breed and imported, they were the mix made of Britain smooth coated blue merle Collie and the Black and Tan Collie from the Highlands of Scotland. The Koolie came to Australia to work as a kennel dog since they are known as the working, farm dog that can adapt to any weather condition. They were bred to be agile and non-aggressive quiet herding dogs, and they have kept most of those good characteristics until today.

Description

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.

australian collie puppy - descriptionKoolie is a medium bred. Their head is small, with a pointy jaw. Ears are pricked, semi-dropped or dropped. Their coat can be smooth or rough, short or medium length, always with the undercoat. The colours can be Red or Blue Merle, solid Red or Black, sometimes with minimal white or cream speckles. They are usually two-coloured or tricoloured, but some of them are actually one-coloured.

Some Koolie have one or two blue, green or yellow eyes. Eye colour is, of course, affected by the gene that creates the coat pattern and eye colour as well.

They are athletic dogs, with fine bone structure but great stamina. Actually, they were breed to be like that – to work hard, be noticeable among the sheep, eat little and be loyal to one person.

Characteristics

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.

Around children

australian collie dog - characteristicsKoolie is naturally energetic, playful and affectionate so they are naturally very good to raise with children.

Special talents

They are known as great obedience dog. They are very famous as the tracking dogs.

Some of them are successful as the rescue dogs, therapy dogs or educators for school children.

Adaptability

This is not a type of dog that will be alone in the house, wait for you and then be quiet while you rest. They need a great deal of activity and they are not such great choice for indoor life anyways. The best thing for them would be the large yard, with somebody home most of the time. They are great if raised in a family, with children and active owners. They will be great for a loner at the farm as well since that is in their blood. They need enough place to run, chase, play, rest on the sun and be active as they please. They get affectionate towards their families, but they will be accepting their new home when they are older just fine.

Learning ability

They are very good at learning. Intelligent, yes, but yet very silly and playful to do what is told all the time. They will surprise you with how quickly they will pick up the new trick but not feeling like doing it every time you would like them to. Everything is a play for them, so it would be best if you know how to play, be affectionate and friendly to become a good owner of this breed.

Health Problems

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.

australian collie puppies - health problemsIf you are careful enough, you will choose your Koolie form patiently chosen breeders, after checking the health history of the pup and the pup’s family. Advisable is to do these things in person and never to buy a Koolie from a pet shop.

Sometimes, pups can be born blind or deaf pups. They have the great chance of joint problems because of their extreme activity. Their need to run, jump and play all the time may result in damage to cartilage and ligaments, especially since they are not aware of their age most of the time.

There is a chance that pup has skin allergies or immune system issues if they are growing on a farm near the chemicals used for plants, so be careful what kind of herbicide you use if you have a Collie.

In some rare cases, they suffer from seizers. If untreated, they can cause death. If you decide to take him to a regular vet check, you will have a happy and playful life together.

Caring The Pet

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.

Feeding the puppy and adult

australian collie dogs - caringWhether you choose canned food or dry food, treats as biscuits or left-overs, the quantity is the safest way of keeping the balanced diet for your Collie. They like raw meat and raw bones. Make sure not to feed them with cooked bones because they can do more harm than good.

Grooming

Since Koolie coat can be very short with the undercoat or a bit longer with undercoat, bristle brushing every 3 or 4 days will be enough for them. Some of them like the water and some of them don’t and that is perfectly fine since there is no need for a regular bath.

Points for Good Health

Lots of activities and lots of love. They express their love all the time and you can learn a lot from them actually. They like raw bones and from-the-table delicious treats but make sure not to overfeed them.

The best type of activity

Games that need them to be fast and think quickly. Running with them, driving a bike with them (but not on the leash!) would be a great fun for them. Why not leash? They are so playful and happy and they tend to jump and run to the side to chase a butterfly or catch the falling leaf.
