History

istrian sheepdog - historyKnown also as the Karst Sheepdog, the beautiful, medium sized Istrian Sheepdog hails from Slovenia, Yugoslavia in the 1600s, being used to guard sheep. In fact, the Karst Shepherd was recognized as the Illyrian Shepherd in 1939.

The dog is fairly scarce in his own country, but interest in the dog started developing in the late 1970s. The Fédération Cynologique Internationale recognizes the breed and it has also been exported to the United States, being recognized by the United Kennel Club.

It is also recognized by a number of smaller kennel clubs. The dogs numbers have declined at certain periods in its history but fortunately breeding programs boosted its numbers.

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

Temperament:

This dog has always made an excellent guard dog, being alert and also being distrustful of strangers. He will need to be trained and socialized if you want him to be obedient to you and more amicable around children in the home as well as visitors to the home.

If he is trained and well socialized, he is able to make a good pet. However, he is an energetic dog, used to working and he isn't recommended for life in the city if there is only a tiny garden. He needs space and will require a large garden.

He will also need to be exercised and not just left to his own devices in the backyard. Because he is essentially a working dog he doesn’t easily fit into the role of pet and companion. He is a working dog and will need to be kept busy.

This is a giant, massive dog in every way and this recently developed standard makes that very clear.

Health Problems

istrian sheepdog puppies - health problemsAs with many other dog breeds, the Istrian Sheepdog is a healthy dog that, because of history of hard work, is robust and able to stand up well to common dog illnesses.

However there is one dog illness that strikes many dogs and at any age, and it is hip dysplasia. This is a malformation of the hip joints.

You'll notice that your once active dog is lethargic, doesn't want to play so much anymore and battles to get up after lying down. The disease is painful for your dog and it can lead to mobility issues. The disease is diagnosed with x-rays and your vet will recommend treatment options to make life more comfortable and less painful for your beloved pet.

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

Exercise:

istrian sheepdog dogs - caringThis is a dog that is used to guarding his flock and he will need to be in a home that has a fair sized garden. He can adapt to life in the city or to the countryside, but wherever he is, he will need sufficient exercise. Take him with you on your walks or hikes and give him some rope- and ball games.

General Care:

Wherever you live in the world, when the Winter winds howl and blow in icy rain or snow, a dog is at an increased risk of illness. You decided to have a dog in your home and it is your responsibility to care for him. Winter weather is downright unpleasant and dangerous for most pets.

Bring your pet in during such weather and provide him with a warm, dry sleeping space. During hot weather, make sure your pet has a cool, shady spot to lie down in, out of the boiling sun. Whatever weather you're experiencing, your pet should never ever be without a constant supply of fresh, cool water.

Provide him with excellent food that is full of vitamins and minerals to keep him healthy. Learn to know what human foods can be toxic for him and cause him digestive problems.

Grooming:

Your double coated Istrian Sheepdog will need a thorough brushing at least twice a week because of his dense, double coat. He does shed and isn't a hypoallergenic dog. His thick coat can tangle easily if it isn't properly brushed and maintained.

Clip his nails when and if they grow long. Other grooming aspects for this attractive dog require checking his ears for infection and also checking his teeth as dental disease can lead to a host of serious illnesses in your dog.

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.
