History

newfoundland dogThe Newfoundland dog is a large working dog. They were bred and used as a working dog for fishermen in the Dominion of Newfoundland, an eastern province of Canada. With their web feet they were also used for water rescue.

The history of the Newfoundland Dog is unsure, but the breed as we know it today originated from dogs which were brought from Newfoundland to England in the early 1800's.

The Newfoundland Club was founded in 1886 so as to promote the 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.

Description

newfoundland dog puppyThe Newfoundland is a large dog standing at between 63cm to 74cm, both male and female. Weight can vary from 45kg to 80kg.

He has a double coat of medium-length straight hair and the hair can be black, brown or gray. Although it is common for the Newfoundland to have a solid-colored coats, you will sometimes find small patches of white on their chest, toes, or at the tip of the tail. Then again you get the less common Newfoundlands where the coat is white with some black markings and these are known as Landseers.

The outer coat is coarse, oily and water-resistant quality, suited to a dog that loves to spend time in the water. The head is broad and large with small ears that he keeps lying close to his head. The tail is long and plumed and the feet are wide with webbing between the toes which aids him with swimming.

Temperament:

As with many large dogs, the Newfoundland is docile and his sheer size makes it that he is best suited to life in the countryside as opposed to living in the city. This is also because this particular dog wants to be close to water where he can swim.

He is a trustworthy, loyal dog and will get on well with children and pets in the home. Training and socialization is always recommended for any dog, but a big dog can often ‘get in the way’ indoors and you want him to lie down or sit when you tell him to. He is an intelligent dog so will respond well to training.

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.

Health Problems

newfoundland dog dogThe Newfoundland can be prone to serious health conditions such as hip dysplasia and gastric torsion. Deep chested dog breeds like the New Foundland are susceptible to bloat, a life threatening condition where the stomach swells, it can twist and the dog can die if help isn’t available. He will be salivating, restless and whining while also trying to vomit.

Giant breeds are also prone to elbow and hip dysplasia, a genetic problem which can ultimately affect your dog’s mobility.

When in any doubt about your pet’s health, get him to the vet.

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

Grooming:

newfoundland dog puppiesYour dog’s coat will need to be brushed at least twice a week as he is a heavy shedder.

Do the nails of your dog as soon as they start getting long. Long nails can hook on things and cause injury to the dog’s paw area.

This is a dog with floppy ears so check inside the ears to prevent ear infections, more so because this is a water-loving dog. The dampness inside the ears can cause bacteria.

Diet:

This is a giant breed and sadly, they have the shortest lifespans. You want to make sure that you keep your giant breed as healthy as possible to ensure he reaches the 10 or so years allotted to him and to also prevent health problems.

Make sure your giant breed puppy and adult has the very highest quality commercially manufactured food to ensure he gets the right balance of nutrients in. This food also makes sure that your puppy rather grows at a slower rate and stronger as opposed to growing too quickly. Rapid growth comes with joint problems.

All dogs, large and small, don’t want exotic, strange food that upsets their stomachs. They want consistency and simplicity and they want tasty food. Give him some homemade food such as cooked chicken, brown rice or pasta and some vegetables such as sweet potato, carrots and spinach. You can add this occasionally to his dry kibble.

Add in some raw meat from time to time too. Your pet will be strong, healthy, happy and content.

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.

Characteristics

newfoundland dog dogsYour beautiful, cuddly puppy will soon become a giant dog with a big appetite. Don’t just buy a cute puppy if you can’t afford to feed him properly and you can’t give him lots of attention.

Your dog will also be shedding, so be aware of these aspects before you bring a large Newfoundland into your home. He is a gentle dog, but his size could be worrisome if he isn’t trained, socialized and supervised.

Newfoundlands are amicable dogs, and while he may like to spend times indoors with you relaxing, he is a working dog and will require exercise and activities for mind and body.

Give this giant of a dog a loving home, and you will have a special, devoted friend like no other.

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.
