Gran Mastin de Borinquen vs Bull and 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 Bull and Terrier is a blend between a number of Old English Terriers and the Old English Bulldog. It is believed that this extinct dog was the start of breeds such as the American Pit Bull Terrier and the Staffordshire Bull Terrier.

They were excellent for hunting rats and weren’t a true breed. The dog was popular in the British Isles and in the United States in the 19th Century. They became rare as different varieties of Bull and Terrier were bred and standardized.

Most terriers have a good deal of Old English Bulldog blood in them so as to provide them with the courage to fight and hunt prey, while the English Terrier blood provided a feisty temperament and longer legs for speed.

Around 1860, the Bull and Terrier breed split into 2 categories – the pure white Bull Terrier and the ones of color. The Bull and Terrier was never recognized as a standardized breed by any of the kennel clubs.

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.

There isn’t too much detail and information on the Bull and Terrier but we can be sure that with the cross between the Old English Bulldog and the Old English Terrier, he would have been a small to medium sized compact, muscular dog, standing roughly between 38cm to 50cm in height and weighing anything in the region of 11 to 22kg.

He would have had a big head, and most of the dogs had a medium to long tail. His coat was of many colors such as white, fawn, tan or brindle and would have been short and smooth.

As far as temperament goes, the Bull and Terrier would certainly be courageous, feisty, independent, strong and energetic. Socialization wasn’t available in those days but with training, this intelligent breed would be affectionate with his human family.

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.

Nobody seems to be 100% sure when the classic Bull and Terrier dog became extinct but it is strongly assumed that it was some time between 1890 and 1920.

People believe that there are actually surviving breeds that could be considered Bull and Terriers. One thing is sure, when you consider that the Bull and Terrier is actually made up of several breeds such as the Bull Terrier, the Staffordshire Bull Terrier, Boston Terrier and American Pit Bull Terrier then you can imagine the character of the dog – brave, hardy, intelligent, feisty, bold, confident and fearless. He was a dog who loved his human family and would have been both friend and protector.

These dogs have been popular around the world, and have had a strong influence in the development of a number of other breeds. Even today, breeders are always looking at ways to develop new breeds based on the descendants of the Bull and Terrier.

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 Bull and Terrier was no doubt a robust breed with few health issues. However his owners of that time would have had to be aware of eye diseases such as cataracts that could have lead to blindness.

Other health issues they would have had to contend with would have been hip and elbow dysplasia, a disease which can cause lameness in a dog accompanied with pain. Because the Bull and terrier was mixed with the English Bulldog, the dog owners would have had to be aware of respiratory health problems, as the Bull dog is a breed that is susceptible to these problems.

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:

Long ago the Bull and Terrier was developed to be a hunting dog, and because he was a blend of the English Bulldog and Terriers such as the Staffordshire Bull Terrier and English Terrier, he no doubt had a short coat that would have required being brushed down from time to time.

Diet:

The Bull and Terrier dog was bred for hunting, and he would have in all likelihood have caught some of his own food. He would therefore have got a lot of protein in. His owners would also have fed him some of their own food too which would have been eggs, home-made bread, rice, fresh vegetables and meat.

He would have had a good quota of raw meat in his diet too and this would have ensured that his coat was shiny and glossy, free of rashes. Dogs such as the Bull and Terrier wouldn’t have eaten commercially produced kibble as that was only introduced in the 1930s.
