Korean Mastiff 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.

This large breed dog is also known as the Mee Kyun Dosa. In spite of his huge size, he isn’t aggressive at all and is bred to be a companion dog.

He was originally developed to be a working dog. The dog was developed in the late 1800’s from European and Asian working breeds. Those interested in dog breeds suspected that a crossing of the Japanese Tosa-Inu with the Neapolitan Mastiff and the Dogue de Bordeaux brought about the breed. They also thought that the Saint Bernard and English Mastiff were brought in later on as well.

These large molosser dogs have been developed through years of inbreeding. It is one of the biggest dogs in Korea.

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.

You can’t help but stare at the Korean Mastiff because of his strong, muscular neck of loose skin that forms dewlaps. His face is wrinkled and he has a cumbersome, sluggish gait.

Cherry Eye:

Cherry eye is a fairly common health issue with this breed. It affects the tear gland of the third eyelid, and if left untreated, can lead to ongoing eye problems.

All dogs have a third eyelid, as well as two tear producing glands to lubricate the eyes. Its an important protective component to eye health in dogs. When the connective tissue that holds the gland in place is damaged or weak, there is a red protrusion of the gland from the lower eye. This is a congenital disorder. Don’t ignore it, but get your pet to the vet so you can catch it early.

Bloat:

Canine bloat, known as gastric dilatation and volvulus can be a killer disease for your pet, more so with deep-chested, large breeds.

Gas accumulation is known as bloat, and its the accumulation of gas which can cause the stomach to rotate. A dog can go into shock from bloat. The reason for this is that the stomach expands, putting pressure on veins. Blood can’t flow as it should and the blood supply gets cut off to the stomach.

Your dog could be vomiting, restless, the stomach hard and bloated or he may be drooling. Dogs who gobble their food down and eat just one large meal a day have an increased susceptibility to GDV than other dogs.

The wrong ingredients of a dog’s diet can also contribute to bloat. High quality food and feeding your pet smaller meals can help.

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.

Grooming:

A Korean Mastiff is an easy dog to groom with his short smooth coat. He is a moderate shedder so a brush twice a week will be sufficient to maintain the shiny, smooth condition of his coat.

Because the dog has lots of skin and folds, these folds will need to be washed and kept clean as grime can collect.

While you're busy attending to his skin check his nails too and check inside and outside his ears for signs of redness and irritation.

Diet:

Puppies use up more energy than mature adults, requiring a diet of good quality protein. Dogs that have been spayed or neutered will require less calories as will senior dogs.

Korean Mastiffs require high quality nutrition, and if its dry kibble, make sure its the best brand. Mix in some home-made food such as cooked chicken, brown rice and vegetables from time to time as well as some raw meat occasionally.

Protein and fat from good sources are top ingredients for your Korean Mastiff. Avoid food with allergens such as corn and wheat, sweeteners, preservatives and colorants.

Make sure your large pet has constant access to fresh water.
