Istrian Sheepdog vs Gran Mastin de Borinquen - Breed Comparison

The Gran Mastín de Borinquen is also referred to as the Puerto Rican Mastiff or the Mastín Borincano and is actually native to Puerto Rico.

The dog seems to have originated long ago already during the 16th century. Its a dog that descends from a number of dogs, and the dog from these crosses became a huge, ferocious dog.

For centuries the Gran Mastin de Borinquen was used to protect the estates of the Spanish nobility. Today the breed is considered rare and it isn't recognized by any major kennel club as a standardized breed.

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 Gran Mastin de Borinquen is a large dog. He stands roughly between 56 and 71cm and weighs in at between 41 and 68kg.

These days the tail is kept long and it is held low. The coat is short in length and harsh with the colour being fawn, black, cream or brindle. You'll also find some small inclusions of white on the coat.

Temperament:

Loyal and protective, the Gran Mastin de Borinquen forms a strong bond with his master, becoming aggressive with any stranger who comes too close to his owner.Its a dog that has been taught to be aggressive so he isn't the best pet to choose if you have children in the home. He isn't the best dog either for first time dog owners, particularly if the person isn't a strong, firm person around him, showing who is boss.

However there are people who have had their pet trained and socialized and who claim he makes a wonderful family pet. The way a dog is brought up can play a large role in the way he turns out.

Train and socialize your Gran Mastin de Borinquen because he is inclined to be strong-willed and for a large, aggressive type of dog, you want him to be obeying you.

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.

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.

Grooming:

The Gran Mastin de Borinquen, with his short coat, is a relatively low maintenance breed. Brush him at least twice a week to keep the coat free of loose hairs. Other grooming requirements are keeping his ears clean and dry. You can ask about alcohol wipes at your local pet shop to use in his ears. Check the nails too and remember to brush his teeth a couple of times a week to avoid dental decay.

Exercise:

You won't find the Gran Mastin de Borinquen being a particularly high energy dog but he also isn't a couch potato. If you enjoy a walk every day for your own good health, include him in these walks and give him a game of ball every now and again.

Diet:

This Mastiff -type dog is large, and they tend to be fairly lazy, not using up great deals of energy. Young dogs however use up more energy and will require a diet with good quality protein.

Dogs that have been spayed or neutered as well as senior dogs will require less calories. If you buy commercially manufactured food, check the labels carefully and buy high quality food for a large breed.

Don't just feed your Gran Mastin kibble everyday but alternate it sometimes, mixing in some raw meat into his kibble or mixing in some cooked chicken, rice and vegetables.

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.
