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.
Derived from the Rat Terrier, the American Hairless Terrier was born in a litter of Rat Terriers in 1972.
The evolution of this breed is very different from other hairless breeds. The American Hairless Terrier was independently developed when a hairless pup was produced in a litter of normal Rat Terriers. The owners of this pup, Edwin and Willie Scott attempted to breed her to other Rat terriers but were not successful in having another hairless pup until years later. Then they had a litter with one male and one female hairless puppy.
From that point on they worked with a veterinarian and a geneticist to develop the breed until it was accepted as a separate breed from the Rat Terrier in 2004 and accepted into the AKC in 2016.
The breed is very rare and with hairless dogs breeding only produces about two thirds of the litter as hairless and one third as coated. If a hairless is bred to a coated terrier, the chances of getting hairless puppies are 50% hairless and 50% coated. It is very rare to get a hairless when breed two coated terriers. The difference between the American Hairless Terrier and other hairless breeds is that the hairless gene in most breed is a lethal dominant gene, but in the AHT it is a recessive gene.
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.
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.

They need to play, and this is the biggest requirement for owners. Be sure you have time for them. This is not a couch potato dog. They have a lot of energy and can be destructive and “barky” if that energy is not dissipated. They are terriers through and through and love to “go to ground” whether going in holes they find or digging the holes themselves. They will go after small rodents like chipmunks. They need to be protected in these activities since their skin is vulnerable to scratches and cuts from brush. Their prey drive is strong, so it is important to protect them from themselves in this respect.
