Sanshu 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.

The Sanshu was developed in Japan a century ago – in 1912 in fact.

It is a cross between the Chinese Chow Chow and the ancient Japanese Aichi. People who know these dogs say they bear a resemblance to other Inu breeds, but it has a straight tail and not the usual curved one that you'd expect.

The breed is rare and they aren’t recognized by any breed organization.

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

He is well muscled with a large head and short floppy ears but until recently the ears have always been cropped. The nose is black, the eyes dark brown and small and he has an alert, intelligent look to him.

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.

The Sanshu is a medium sized dog standing at between 50 to 55cm in height and weighing in the region of 20 to 25kg.

There is also a smaller variety. This dog has a wedge-shaped head with a tapering muzzle, dark almond-shaped eyes with small erect ears.

Nonetheless, every dog can fall prey to some of the many dog illnesses there are, and some of these diseases can be skin allergies, hip dysplasia, bloat, digestive issues, cherry eye, cancer and obesity.

Eye Problems:

The condition of the eyes can give away some ideas of a dog’s health. Eye discharge can be a sign of an infection or an allergy. If your dog’s eyes aren’t clear and there is a constant discharge, talk to your vet and get to the root of it. Left untreated, there are some eye diseases that can lead to blindness.

Skin Allergies:

Just like humans get all kinds of skin problems, dogs also do. It can drive them crazy and you see them scratching and biting. Skin allergies are sometimes caused by insect bites or allergies to medication or food. You might see excessive itching, scratching, a nasty rash, watery eyes and chewing of the paws. Atopic dermatitis is an inflammatory skin disease and you will need to get your pet to the vet.

Dental Problems:

You need to check inside your pet’s mouth and make sure that a bad tooth isn’t causing your pet tremendous pain and infection. Sometimes missing teeth can also interfere with the way your pet eats.

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.

Brush the coat twice a week to rid the coat of loose hairs.

Check the ears and eyes for infection.

Feel for unusual lumps on your pet’s body.

Provide your pet with a warm, dry place to sleep.

Keep your pet’s vaccines up to date to eliminate killer canine diseases.

Have your pet spayed or neutered to avoid unwanted puppies.

Feed your pet well. A Sanshu dog will require the best dog food there is. If you give him commercially manufactured food make sure it is one of the better brands to avoid toxic ingredients.

To add some variety, feed him some home made food occasionally which can be added to his dry kibble twice a week. Boiled chicken, brown rice or pasta and spinach, sweet potatoes and carrots are a healthy choice for your pet. Try and include some raw meat into the diet as this can help in fighting off horrible skin diseases. Ensure there is always a bowl of fresh, cool water for him.
