Gran Mastin de Borinquen vs Blue Paul 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.

Known also as the Scottish Bull Terrier, the Blue Poll or the Blue Poll Bulldog, the Blue Paul Terrier’s origins, as with many unusual dog breeds, are still not known precisely. However they do appear to have been bred with Staffies at some point and appear to have slowly transformed into the Staffie or Pit Bull as we know them today.

There doesn’t seem to be much documentation on the dog’s origins, making many stories of its origins to be looked upon as folklore. It seems as if the dog originated out of Scotland. The name ‘Paul’ is included in the name simply because it is believed that John Paul Jones, who was a sailor, brought the dog to the USA in 1777.

Because this dog has superb fighting skills, it was introduced as part of Staffordshire Bull Terrier breeding in the early 19th century. It is believed that the first dogs came with English immigrants to the United Stated in the middle of the 19th century. At some time, the dog became extinct, but dates of this time can’t be established.

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.

Staffie/Pit Bull Look Alike

The Blue Paul Terrier was a smooth coated, medium sized dog. His coat was mostly dark blue but this sometimes varied to red or brindle. He was a muscled and well built dog, much like our pit bull terriers. He weighed about 20 to 25kg kg, measuring up to 56cm at the withers. He had a broad chest, large head with small cropped ears and a tail that was set low. He is a dog that always stood strongly on his legs. It seems as if he had an aggressive nature as they were used by local dog fighters.

Aggressive by Nature

There is not much information on the temperament of the Blue Paul Terrier, but we can assume, that because he was a Terrier, he would have been full of character and self confidence. Most Terriers don’t actively look for a fight, but will certainly get into a fight if provoked. Aggressive by nature and a fighter, the Blue Paul Terrier possibly had some Staffordshire Bull Terrier in him, so his temperament would be that of a fighter.

He may have been able to live peacefully with children and other dogs and cats in the home, but he would no doubt have had to be raised from a puppy in such a household. Stubborn and headstrong, he would require a firm owner who could take charge of him and training would have been imperative for such a dog.

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 is quite certain what the Blue Paul Terrier was like. He definitely seemed to be a mix of Pit Bull and Staffie – the same compact, muscular build with a look that speaks of confidence and boldness.

Perhaps if the Blue Paul Terrier wasn’t used for fighting, he might well have made a good pet with training and socialization. Nobody really knows. Maybe he was so aggressive that when dog fighting didn’t work out, and it was discovered that he wasn't really pet-material, nobody bothered when the breed went into extinction. That's the thing with Blue Paul Terriers, nobody is really certain about what they were really like.

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 Blue Paul Terrier Health was generally a healthy dog, but he would no doubt have had the same common dog ailments that most dog breeds have to contend with. All those years ago, when the Blue Paul Terrier was ill, his owner no doubt would have taken him to see the veterinarian for a full screening.

Just like with other dog breeds, he would have been watched for hip dysplasia , ticks and fleas, cataracts and skin infections. It is possible that in those days, owners of the Blue Paul Terrier weren’t aware of how plaque could cause dental problems or gum disease.

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.

Feed

Because these dogs were used in fighting, it is a breed that no doubt would have required plenty of exercise and mental stimulation to keep him fighting fit. No doubt he would have received a high quality food to build up his strength and stamina. Because he was no doubt a high energy dog, his owners would have had to give him nutritious food and ensured fresh, clean water for him.

Grooming

The Blue Paul Terrier had a short, smooth coat, so they were no doubt low maintenance dogs who received a brush down every now and then to remove his loose hair.
