History

spanish mastiffThe Spanish Mastiff is a giant breed that comes from Spain. He has always been a guardian dog.

He is an ancient dog breed, in fact dating back to medieval times. He has always been a guardian of livestock, protecting them from attacks from wolves and other predators.

The first breed standard of this pure breed dog was made by the FCI in 1946. A breeding program was also formed for this dog In 1981.

The dog was recognized by the United Kennel Club in July 2006.

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

spanish mastiff puppyThe Spanish Mastiff weighs between 52 and 100kg and the dog’s height is between 72 and 88cm. He has a thick, heavy coat with rustic colors of fawn, black, grey, reddish and yellow as well as brindle.

He is powerful and muscular with a huge head. The ears are medium length and floppy and the tail is long. If you were looking for a puppy, the American Kennel Club is the only site which has 100% puppies from AKC-Registered litters.

Temperament:

Large, kind, gentle and intelligent, the Spanish Mastiff is well balanced. When you see him you won’t find a dog that is light on his feet and who jumps around excitedly. He is a dignified, intelligent dog, quiet and calm.

Even though he is so calm, it is still a good idea to have him trained and socialized as his very size could be a problem. When you tell him to lie down, you want him to listen to you. This big, gentle giant is devoted to his human family ad takes the role of guardian and protector seriously.

He isn’t suited to life in the city but is better suited to a large property, also because he has a loud bark.

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

spanish mastiff dogIt is good to be wise about some of the common dog problems there are that could plague your Spanish Mastiff. Vets are very familiar with these dog illnesses and they tailor their treatment to suit the needs of your dog.

Remember to get your pet vaccinated against the terrible diseases you get that can kill a dog – rabies, parvo and distemper.

Obesity:

People often think that obesity is something that isn’t dangerous, when in fact it is a serious disease that can cause joint problems, digestive disorders, heart disease, back pain and hip dysplasia.

Dehydration:

Dogs rely on water just like what humans do to keep them healthy and functioning properly.

Water is critically important to every organ and also assists with digestion. Your dog is panting and urinating throughout the day and needs to replace the liquid he loses.

Dehydration in dogs results in loss of electrolytes, such as sodium, chloride, and potassium.This is bad as these minerals have important functions.

A dog that is dehydrated has loss of appetite, loss of skin elasticity, is lethargic, has sunken eyes, wants to vomit, has a dry nose and thick saliva. No dog should ever be left without a constant supply of fresh, cool water day and night.

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

Diet:

spanish mastiff puppiesThese are giant breed dogs, so you have to be careful with the way you feed them. Large dogs like these are prone to hip dysplasia so you need to choose a food which has ingredients that work to prevent this disease.

You have to be very careful that you don’t overfeed your dog so that the extra weight puts strain on the joints.

This dog will do well with some raw meat added into his diet. Also, include home-made food too. Boiled chicken, brown rice or pasta, sweet potatoes, carrots and spinach chopped up and added to his dry kibble for giant breeds. Added in twice a week can do him the world of good.

Remember to never leave your dog without a constant supply of fresh, cool water.

Grooming:

A good bush of the thick coat twice a week will keep the Spanish Mastiff looking his best.

The nails will also need to be trimmed regularly to avoid overgrowth and to avoid the nails catching onto things. The ears too should be checked regularly to avoid dampness inside the ear which can cause bacteria.

Exercise:

As a fully grown adult, the Spanish Mastiff isn’t a frisky, frolicking dog but he will still require daily exercise. Options for exercise include long walks, hikes, swimming and ball games.

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.
