Istrian Sheepdog vs American Mastiff - Breed Comparison

Known 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.

The history of the American Mastiff is entirely tied to the old European Mastiffs but in particular the English Mastiff. The developers of the American Mastiff crossed the English Mastiff with the Anatolian Mastiff at the Ohio kennel, Flying W Farms. The founder of this breed is Fredricka Wagner. Because of this the English Mastiff and the American Mastiff look very much alike. The difference between the two is that the American Mastiff was bred to have less health concerns than the English Mastiff and without the drooling. In 2000 the CKC acknowledged that the American Mastiff and the English Mastiff were separate breeds.

This is a medium sized, muscled, strong dog with an iron-grey coat that has shades of deeper grey. His beautiful coat is long, thick and fairly harsh to the touch, with the undercoat protecting the dog against cold weather.

Around the neck area the hair is longer, forming an eye-catching-like mane. The stomach area has longer hair too. He has a noble look about him with kind, brown eyes and a round skull. The muzzle of the dog is dark, the limbs long and muscular and the tail is long and covered in thick fur.

The dog is slightly longer than its height, and both males and females stand at 54 to 63cm in height and weigh between 26 and 40kg. The long tail reaches right down to the hocks. The ears of the dog are fairly short and are floppy.

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 crossing of the English Mastiff and the Anatolian Mastiff resulted in a Mastiff with a much drier, less drooling mouth than the other Mastiffs. This is a giant, massive dog – powerful and muscular. With a wide head that is rectangular rather than square. Their eyes are dark amber, and their ears are high on their head and rounded. With a medium size muzzle, black mask and heavy head, the American Mastiff is a handsome dog.

Their chest is broad, deep with ribs that extended backward. He has strong legs that are parallel and wide set. He also has a long tail. Puppies of the American Mastiff are born almost black and as they grow their coat color lightens. In addition, it is important that they have a wrinkled forehead as well and a scissors bite is preferred.

Your Istrian Sheepdog is a unique, strong-willed dog that is used to guarding, and working and he wants to be kept involved and busy.

He is wary of strangers and makes an excellent guard dog for any family home. Remember that it is never good to invest in a dog purely for guard dog purposes. A dog such as the Istrian Sheepdog is a social creature and he also wants- and needs to be part of a human family that provides him with plenty of interaction with them.

The Istrian Sheepdog is a loyal, loving dog who is capable of forming strong bonds with his human family. With proper training and socialization he makes a good friend of children and the elderly too.

Include him in all your family activities just like any human family member and he will make you a splendid, courageous pet.

A love of children and devotion to his pack (family) is bred into the American Mastiff. He is non-aggressive unless you threaten his family or his children. Then he becomes courageous, protective and defensive. This is a gentle giant most of the time, however due to size and the need for strong leadership, the American Mastiff should be socialized and trained early. If they are socialized and trained they will be calm, gentle dogs. They will remain protective and alert, but they will be friendly with strangers. They love to please their people and being highly intelligent they learn fast.

As 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.

American Mastiffs seem to have fewer health issues than other larger giant breed dogs. However, they can experience allergies as many large, wrinkled dogs do. They also might have a tendency toward eye issues, hip dysplasia, cancer and heart disease. Bloat might be the most life-threatening issue many American Mastiffs experience.

Exercise:

This 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.

Giant breeds like the American Mastiff are known for growing rapidly as a puppy and therefore proper feeding and nutrition is essential. The slower your American Mastiff grows, the better. Make sure your puppies get enough phosphorous and calcium in their high calorie diet. Free feeding is not recommended. Feed puppies up to 4 small meals per day and feed adults twice a day.

Health issues

As previously mentioned this breed is a fairly healthy one, There, are however, certain evaluations you should do with your American Mastiff puppy to be sure she is in good health. These tests would include an elbow and hip evaluation to check for dysplasia. He should have an ophthalmologist and cardiologist examine him as well. Most American Mastiffs will not have any problems, but these evaluations will help to prepare you if they do. The wrinkles in your dogs; face, around the eyes and muzzle must be kept clean as they can become infected if you don’t.

Exercise and games

Unlike the way he looks, the American Mastiff is not a couch potato, but neither are they a high energy, exercise machine. They do well living in apartments or homes, with or without a fenced in yard. They need a long walk every day. They need mental stimulation through exercise and games. Make sure they learn to love to play so that they don’t become lazy as they age.
