History

The Molossus has always been a popular dog and they have been around since ancient times. Mastiff type dogs are termed as Molossus.

Of course, when looking at the origin of the dog, there are many unsubstantiated claims about it. It has always been believed that the Molossus was a Mastiff-type dog, ferocious in battle. The Romans were dog breeders and recognized that the Molossus was a talented dog – good at guarding and herding.

Over the centuries the dog has changed but it is believed it was a Mastiff-type dog with a number of other breeds included in its origins such as the Rottweiler, Pug, Bulldog, Great Dane, Alano Espanol and Saint Bernard.

The Molossus isn’t a dog breed itself but rather a category that other dogs belong to. Today there are Molosser clubs and Molosser shows around the world.

jack russell terrier - historyThe popular Jack Russell Terrier was developed in Devonshire in the south of England in the late 1800's so as to hunt foxes.

Often believed to be the Parson Russell Terrier, the Jack Russell Terrier was developed by Parson John Russell. This is where the dog gets his breed name from. Some people get the Jack Russell Terrier a little bit mixed up with the Parson Russell terrier, when it fact its actually a different breed, but sharing a common ancestry.

The Jack Russell Terrier is smaller than the Parson and bigger than the Russell Terrier. The breed became known in the U.S. by the 1930s and the Jack Russell Terrier Association of America wanted recognition by the American Kennel Club, which was granted in 2000.

Description

This Ancient dog breed from Greece has different descriptions of what it really looked like. It seems to have always been large to medium sized dog standing in the region of 50 to 76cm in height and weighing anything from 25 to 55kg.

The coat is mostly short and smooth and can be in a host of different colors. They are large boned dogs, solidly built with medium sized floppy ears, a short, thick neck, short, broad muzzle and a long tail which was later docked.

Molossers typically have heavy bones, pendant ears, and a relatively short and well-muscled neck, with a short, broad muzzle. These Molossers have always been used for a variety of jobs where strength, perseverance, speed and braveness are required. They have been used as rescue- and guard dogs, protecting livestock from predators.

Temperament:

The Molossus dogs all have the same kind of characteristics which have been bred into them. From their working days, they are known for their tremendous courage, taking on wild animals to protect their livestock.

They are territorial, wanting to protect their human family and home from intruders.They have also been bred to be loyal, loving family pets, and being highly affectionate, they want to be involved in the activities of the family.

This breed is gentle and loving, social and active and gets on well with other pets in the home as well as with children. They’re intelligent dogs and will need to be trained and socialized to ensure they are obedient and amicable with visitors to the home.

jack russell terrier puppy - descriptionThe Jack Russell Terrier is a small dog that weighs between 6 and 8kg and stands at between 25 – 38cm. The body length of the dog should be in proportion to the height.

He is essentially a white dog with orange or fawn colored patches. The coat is mostly smooth and short, but the coat can also be longer and rough or it can be broken which is a combination of rough and smooth. Regardless of coat type, they are dense, double coats which will require brushing at least twice a week to remove loose hairs. He may also be tri-colored such as being white with black and tan patches.

He has alert, bright dark brown eyes and ears which are somewhat erect and which flop over at the tips. The tail has always been traditionally docked, giving him an attractive, compact look about him but unfortunately the tail is often left long on the dog these days.

Temperament:

Your Jack Russell Terrier is a lively, tenacious, bold, fearless, feisty, cheeky, confident, independent, intelligent and full of life dog. He is super energetic and exuberant, spirited and full of personality.

There are some dog owners who are exhausted by him and would prefer a more quieter dog breed as their companion. Nonetheless he has some excellent characteristics such as being a totally devoted and loving dog.

It is why it is a good idea to have him trained and socialized as it calms him down and makes him more obedient. He is very intelligent and training him will be easy.

Characteristics

The Molossus, contrary to what many people think, isn’t a vicious dog, but rather a good natured dog that makes a wonderful family pet.

These dogs are known also for being hard working dogs with characteristics of bravery. They are dogs who may look fairly tough, but they are actually gentle, calm and sensitive. It’s a bad upbringing from the owners that gives any dog bad characteristics.

Train your Molossus, have him socialized and be a responsible and loving dog owner, and these dogs promise to make you a splendid family pet.

Health Problems

These large dogs are particularly prone to health issues such as hip dysplasia, a genetic condition. A poor diet as well as environmental factors can contribute towards the disease too as well as rapid weight gain and obesity.

This disease develops because the dog’s hip joints haven’t developed properly. The hips then partially dislocate, and the dog has pain and battles to get around. If your dog shows signs of hip dysplasia, he will need to get to the vet to do a physical exam and come up with a treatment- and management program.

jack russell terrier puppies - health problemsThis particular dog breed has a reputation for being healthy and living to a good age such as 16 or 17 years of age. Of course he needs to be given proper care to reach such a good age.

Some common dog disorders you might want to be aware of are -

Eye disorders:

Lens luxation is actually a common hereditary disorder in these dogs, but even so, with good care, your dog isn’t likely to battle with it. What happens is that the lens in the eye becomes displaced. There are two types, with Posterior luxation being the lesser severe one.Treatment is available.

Musculoskeletal conditions:

Patellar luxation is an hereditary disorder affecting the knees of the dog. The kneecap slips off the groove where it sits and you may notice your dog running while holding his hind leg in the air. It can sometimes slip back in place and then you see your dog running in his usual way. It becomes more serious when it affects both legs.

Caring The Pet

Exercise:

These dogs were bred to be working dogs and they have always spent their time outdoors performing a guarding or rescue role. Today they require a lot of exercise – walks and ball games – as they are dogs with a lot of energy.

Diet:

Essentially a large breed, the Molossus will need a commercially manufactured food of high quality if you opt to make use of the convenience of these foods.

Make sure to choose one manufactured for large breeds and which is free of a host of bad ingredients such as corn, soy, wheat, dairy, artificial colors, sweeteners and preservatives.

You want dog food which is high in protein and fat. Try and include some home-cooked food such as boiled chicken, brown rice, pasta and vegetables. An ingredient to look out for in your dog’s food is omega-3 fatty acid to help keep the skin and coat shiny and healthy. Puppies particularly benefit from DHA, or Docosahexaenoic acid, a form of omega-3 fatty acid that is good for brain development.

Grooming:

Brushing the dog’s coat twice a week will be necessary to remove loose hairs, especially during the shedding period. When you brush him, check for ticks and fleas and speak to your vet about flea treatment if necessary. Ears and eyes should be checked and cleaned regularly.

Exercise:

jack russell terrier dogs - caringThe Jack Russell Terrier isn’t just a small dog that can be left to his own devices. He will need proper training and socialization early in life to make him obedient and better to get on with.

He may be a small dog, but he certainly won’t do in the city where he is cooped up in a place with a handkerchief of a garden. He needs lots of space to run and play. He wants his human family to join in with walks, hikes, ball games and swimming.

Diet:

You can buy excellent commercially manufactured dog food which caters for energetic small dog breeds like the Jack Russell Terrier.

Once you have selected the best one for your pet, with dry kibble being better in terms of dental health - you can also add in some brown rice, vegetables and cooked chicken. This is highly beneficial to all dog breeds. A little bit of raw meat can sometimes be added in too.

The bottom line is to to prevent your pet from eating foods high in preservatives, additives and fillers. Never leave your pet without a constant supply of fresh, cool water.
