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.

long haired chihuahuaThe short haired Chihuahua is such a recognizable dog breed, probably because of his tiny size, but did you know that you also get a long haired variety?

Looking quite a bit like a Pomeranian, the only difference between the two types of Chihuahua is the length of the coat.

This small dog dates back to Mayan times and while it may well have originated in Mexico, its popularity saw it becoming a sought after pet in other countries too.

To get the long haired Chihuahua, breeding programs were established and the short-haired variety was mated with other long haired toy sized dogs such as the Pomeranian and the Yorkshire Terrier.

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.

long haired chihuahua puppy - descriptionYour long haired Chihuahua will have a coat that is soft and slightly wavy. He weighs between 1 and 3kg and stands at about 15 – 23cm. He generally sheds throughout the year with a couple of heavier shedding periods during the year.

Don’t be fooled by the long, thick hair on the long haired Chihuahua as it doesn’t protect him from the cold – in fact he doesn’t tolerate the cold well at all, and is essentially an indoor dog. The ears are erect and feathery and the tail is full and plumed, lying over the back. He has a ruff on the neck, which is often described as a mane.

Temperament:

Chihuahuas are such bright-as-a-button little dogs and they’re intelligent too.

It’s difficult to say how a dog’s temperament will turn out, because breed, lifestyle and the type of owners can all make a dog a certain way.

Socialization and training can sometimes help with a dog that has bad genes. There are some people who say the Long haired Chihuahua is a nasty, aggressive little dog who’ll easily give you a nip but they’ve got a good reputation with many other dog lovers.

They love their own human family but may take quite a while to chill towards other people and other dogs too. They’re more ‘birds of a feather flock together’ type of dogs, preferring to get on with other Chihuahua dogs.

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.

long haired chihuahua dog - characteristicsThe Chihuahua is such a feisty, courageous, confident little dog who also believes that he is part- lion. He is loving, sweet and gentle and just loves being picked up and petted non-stop. He looks up at you, moving his front paws up and down to tell you that he wants to be picked up.

He is in 7th heaven when he can be cuddled up in your lap. You just have to teach your children to be very careful with him and not enter into games with him that are too rough and tumble. Tiny he may be but he makes a great watchdog too, barking and alerting you to strangers.

His small size makes him perfect for life in the city or in the countryside. Just be careful when in the countryside lest an Eagle or Owl scoop him up and carry him off to some faraway nest.

He doesn’t need a great deal of exercise either and you can actually keep him happily busy with some games indoors. He’ll always welcome walks with you though.

This small dog is full of life and confidence and he is ready to be your constant, loving 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.

long haired chihuahua puppies - health problemsWith good care, you’ll have your long haired Chihuahua with you for a long time – 15 years and longer.

Parasites:

Make sure to de-worm your Chihuahua. Worms and other parasites can be deadly for your pet and the vet will do preventative deworming on a regular basis.

You Chihuahua will need to be vaccinated when he is a puppy and even when he is an adult, although less often. These vaccines will protect your Chihuahua from the likes of parvo, distemper and rabies. Have your chihuahua spayed or neutered.

There are so many puppies in the world who can’t find homes. Desexing your Chihuahua is a responsible way to ensure your pet doesn’t have puppies. Spaying and neutering can actually be beneficial for your dog’s health.

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.

Grooming:
