Gran Mastin de Borinquen vs English White Terrier - 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 English White Terrier was developed in the 1860’s by a group of breeders from the Sealyham terriers, the Jack Russell terrier, and the Fox Terrier. These breeders were looking for a white terrier that could be more successful in the show ring than the current prick-eared English terrier. They named their new breed, the English White Terrier or the Old English terrier. In later years in the United States, the English White Terrier was mixed again with the Rat Terrier and the Old English Bulldog to create both the Boston terrier and the Bull terrier.

Although the breed did not last long it did have a prestigious ancestry that could be traced back centuries in England among ancient terriers. The word terrier was in use in England in 1440, showing that the dogs were well known at that time. Most historians agree that the dogs were even older than the 1400’s. It is believed that terriers who “went to ground” after prey, existed as far back as the time of Christ in England.

Most of these ancestors of the English White Terrier were not white. White terriers came onto the scene around the 1700’s.The first picture of white terriers appeared in 1790 when Sawre Gilpin, a British artist, painted “A Huntsman with Hounds Foxhunting” and the terriers in the painting were white with brown marks. Others began to show the same kind of terriers in their artwork – white coated. Before this it is believed that breeders killed the white terriers at birth because they were often deaf and inferior to the other terriers. In the early part of the 19th century, the white terrier began to be completely white with no markings. The Kennel Club recognized them in 1874 as the White English Terrier.

The breed faced many genetic issues, deafness and the Kennel Clubs felt there was no difference between the current White English terrier and the English White terrier despite the difference in their ears. The new English White Terrier had dropped ears instead of Prick-ears. They considered them to be the same breed and not even different types. They were the smallest of all terriers and considered to be a good pet but not a show dog or a working dog. Because of this it was not very popular, and it actually had been bred to be a show dog and not a working dog. The English White Terrier was not recognized by any Kennel Club and within 30 years it was extinct.

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 English White Terrier had a pure white coat with no markings of any kind. His coat was short, hard, and glossy and his body was firm, muscular and hard. The breed was small – almost a toy. They had a body like the Manchester Terrier. They had long legs and large feet. The tail was medium size and straight out from the body.

The English White Terrier had a very refined head with a fairly long muzzle. Their bite was even, and their eyes were brown, amber or black. Their ears dropped – unlike the pricked ears of the White English Terrier.

Noble, courageous and loyal, a trained, socialized Gran Mastin de Borinquen who has learned simple commands such as sit, down, come, stay, lie-down and heel will be an absolute pleasure to have around and be a well behaved, obedient companion for you.

Your Gran Masin is a dignified, loving animal, but because of his size and his origin, bred to be aggressive, he isn’t looked upon as the first choice when you’ve got small children in the home. With the right owner – fair, firm and loving - he makes a splendid pet.

The English White Terrier was affectionate and devoted to his family. It was the softest tempered of all terriers and made an excellent pet. Some of the English White Terriers were animal aggressive while others were not. Training was difficult because of the wide-spread deafness in the breed. IT loved to be cuddled and held. They were also tenacious and game for any type of fight or hunt despite their size and deficiencies.

Your Gran Mastin de Borinquen can get to 12 years of age with good care. Mastiff-type dogs like this can be prone to eye problems as well as having to tackle joint problems such as hip dysplasia.

Other issues that can appear in this breed, but are unlikely be cancer, bloat, hypothyroidism and von Willebrand’s Disease which is a bleeding disorder.

Remember to do daily inspections of your Gran Mastin de Borinquen for fleas and ticks, particularly during the Summer month. Toxins introduced into the body by a tick bite for instance can make your pet seriously ill so that veterinary intervention is required.

The breed was considered to be unhealthy for the most part and became extinct because of this. Many complained that the breed was inbred and had a weak constitution because of it. Deafness was prevalent throughout the breed. This deafness occurs in many white animals, but the English White Terrier had the highest rates among all white dogs.

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.

Feeding

It was best to feed the English White Terrier 1-2 cups of dry meal per day served in 2 meals.

Health issues

As mention previously, the English White Terrier was congenitally deaf and had a weak constitution.

Exercise and games

This little dog with all its problems was still a very energetic dog and needed considerable exercise. Owners had to develop exercises and games to keep the English White Terrier occupied as with any terrier. If they didn’t have a job or something to occupy their minds and bodies, they were destructive.
