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.

chihuahuaQuite a bit of the Chihuahua’s history is shrouded in mystery, and there are different versions about its origins.

While historians speculate, most will agree that the tiny dog hails from Mexico. The UK Kennel Club considers the smooth- and long coat Chihuahuas as 2 distinct breeds.It was in 1904 that the Chihuahua became a registered breed by the American Kennel Club.

Chihuahua is actually the name of a state in Mexico, and it is amazing that Chihuahua specimens were found way back in the 1800's already. Today the Chihuahua is a very popular dog breed in several countries.

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. Do not remove the front dew claws. His tail is thick and wide then gradually tapers at the tip.

chihuahua puppy - descriptionThe small Chihuahua stands at about 15 – 23 cm and he weighs about 1,5 – 4kg.

You’ll notice that he shivers when he is excited or when he is cold or frightened. Some people buy him a jersey to don on cooler days. With this tiny toy dog, you get a short- and a long coated Chihuahua.

This is the smallest dog breed and his coat is available in a number of colors such as fawn, tan, white and black. It is the dog’s round apple-shaped head which is a distinctive feature. He has erect ears and huge fruit-bat type eyes.

Temperament:

The Chihuahua is such an alert, fun-loving, feisty little dog, and though he may appear to be an ideal pet for children, he actually isn’t. He is too dainty and frail, and a child, during play, could accidentally crush him.

It’s a pity though because he just loves being around his human family. He is also a highly strung dog, and given the chance, he’ll nip and even bite during games. It is why socialization and training are considered important for the Chihuahua.

Just like with children, how you raise and treat your Chihuahua will determine how he turns out. He is such a sweet little dog that training and socialization can remove these unwanted characteristics. He is very intelligent and responds well to training.

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.

chihuahua dog - characteristicsSmall and feisty, the Chihuahua’s personality isn’t set in stone, and the tiny dog can be either shy and timid or he can be social, confident and jaunty.

They're always loyal and affectionate to their human owners, but they don’t get on too well with- and are wary of small children who aren’t disciplined and who could hurt them.

With his big eyes and big ears together with his comical antics, they can be a source of entertainment for their human owners. He is easy to train too and even though he is small, he doesn’t think he is, and he is willing to use his big personality to make you a loving, loyal and devoted companion.

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.

chihuahua puppies - health problemsThe Chihuahua doesn't have any particular health issues, more so when you get him from a reputable breeder. With good care he can reach 20 years of age.

Hypoglycemia:

Known as low blood sugar, hypoglycemia is easily treatable, but if it isn’t caught early it can be fatal.Hypoglycemia makes a dog lethargic and he’ll shiver and could go into a coma. Get him to the vet immediately.

Bloat:

Gastric Dilatation or bloat is when the stomach twists, it becomes enlarged and blood supply is cut off to the stomach. Left untreated, it can be fatal.

Dental Disease:

Chihuahuas are susceptible to dental problems, so you will need to brush his teeth 2 or 3 times a week to prevent tartar build-up, gum disease, loss of teeth and other diseases.

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.

Diet:

chihuahua dogs - caringAlways make sure to choose a high-quality dog food for your Chihuahua as this will keep him in tip-top health. A healthy Chihuahua can live to be 20 years of age. Speak to a veterinarian for recommendations on the best type of food to feed your tiny pet.

Giving him some home-made food such as brown rice, vegetables and cooked chicken for instance will be a welcome treat for him. Make sure he always has a bowl of fresh, cool water close by.

Exercise:

The Chihuahua may well be the smallest toy sized dog breed, but don’t be mistaken – he has plenty of energy and is constantly prancing around. He is more than capable of living in a small apartment, but even so he needs to be taken outside every now and then for a game or a walk.

Be careful with your small pet though, as too much exercise can lead to elbow- and hip dysplasia.

Grooming:

The Chihuahua is a moderate shedder with Spring being their heavier shedding period. Because of his small size, you won’t be bothered by too much hair. The short haired Chihuahua is easy to maintain and with a rubber brush, you can brush him gently twice a week.

You’ll also need to clip his nails and if you can’t manage this your vet can also help you.
