History

The Pražský Krysařík is a small breed of dog from the Czech Republic.

prazsky krysarikYou won’t find this dog outside the Czech Republic, which is a pity, because as one of the smallest breeds, it’s a great choice for people with small properties.

It’s not a new breed, and there are records of it having been around in the Middle Ages, being valuable for catching rats.

The breed went through a decline in the 1980s, but their breeding program was started, although it isn’t an FCI acknowledged 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

prazsky krysarik puppyThe Pražský Krysařík is a small dog standing at between 20 and 23cm in height and weighing between 1.5 and 4kg.

The Prazsky Krysarik may be small, but he is robust with a broad chest and a lean body with a fragile, lizard like head, much like a Chihuahua. The legs are fragile and thin. The ears are fairly large and erect and he has a long tail. The coat is short, thin and glossy and is mostly black and tan.

Temperament:

The Prazsky is known for its playful, lively nature, and they’re spunky and intelligent dogs too and will be more than capable of being trained and socialized.

Even though he is such a tiny dog, it will be to his benefit to have him trained and socialized.It makes the dog well balanced and they become well behaved so you can take them anywhere.

They are such friendly, social little dogs too and they love being around their human family. They certainly don’t like being left in the backyard, cut off from their human companions.

They're small enough to be indoors a lot, being able to easily slot into life in the city or in the countryside. They get on well with children and other pets but kids will have to be taught how to treat him with kindness and respect, as those tiny little legs could snap.

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

prazsky krysarik dogThe Prazsky is a robust dog but there are some diseases that can affect a dog, and skin symptoms such as itchiness or an unusual lump will need to be seen to.

Other problems such as excessive drooling, cloudy eyes with discharge, distended abdomen and discolored gums are all reasons to seek the help of your vet. Small dogs like this tend to be prone to dental disease, so keep an eye on his teeth.

Some people look at buying health insurance because they know too well that veterinary costs can add up quickly, even for a tiny little dog like this.

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:

prazsky krysarik puppiesIt doesn’t matter what size dog you have, each one requires high quality dog food, whether commercially manufactured or home-prepared.

Portion sizes should be appropriate to your dog’s size and activity levels. Dogs thrive on simplicity when it comes to food as this prevents them having digestive problems. Boiled chicken, brown rice or pasta and sweet potatoes, spinach and carrots all chopped up and added to your dog’ dry kibble as a treat every now and again will do wonders for your pet.

Fresh, cool water should always be available to your pet around the clock.

Grooming:

The short, smooth coat of the Pražský Krysařík makes him a truly low maintenance little dog. Just give him a brush twice a week and wipe him down with a damp cloth and he’ll always be gleaming like a new penny.

Have his nails trimmed and always check his teeth during these grooming sessions. Smalls dogs battle with dental disease, and this can cause havoc in the body of your small pet.

Exercise:

Walk your tiny pet at least once a day. It just gives him the chance to sniff around a bit and see the world in a new light. He doesn’t require a lot of physical activity, but they will still need regular exercise to stave off obesity.

Get your Pražský Krysařík spayed or neutered if you’re not intending to allow your pet to have puppies. These little dogs can have between 1 – 3 puppies. There are many pros to this procedure for dogs.

Make sure his vaccinations are up to date to avoid some of the deadly dog diseases you get such as parvo-virus, distemper and rabies.

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.
