Gran Mastin de Borinquen vs Black and Tan 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.

There is limited information on the Black and Tan Terriers since it is extinct. Black and Tan terrier came out of the “Terrier Wars” between the British and the Welsh in the late 1800’s. With dog shows on the rise, a race began to develop terriers that “belonged” to the Welsh or the British. The Black and Tan Terrier started out as the “Old English Broken-Haired Black and Tan”. The outrages Welsh responded with their first dog show filled with Welsh only terriers. There were 90 dogs at this first show. During this time, the British could not get their act together in respect to starting a club. Even agreeing on the name was difficult for them. Unfortunately, the dogs from both countries were not truly a “breed” but rather first-generation crosses between a wide variety of terriers. These terriers included breeds such as the Lakeland Terrier, the Welsh Terrier, the Patterdale Terrier, Fell Terriers, Border Terrier, Scottish Borders and the Manchester Terrier. The winner of that first dog show was a terrier cross between a Smooth Fox Terrier and a Border Terrier.

In 1885 both the Welsh and the British Black and Tan Terrier were featured. However, the English could not get the club together, so they were dropped from the Kennel Club Listings and only the Welsh Terrier was offered. The Black and Tan Terrier became extinct before 1900.

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 Black and Tan Terrier was an active, alert dog. A ratter as most terriers are. With a sleek coat, tan markings and thumbing, he was a handsome dog. Looks very much like the other terriers of his size and color with a truncated tail. He had small erect ears and a snout that was moderately elongated.

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.

He was an alert and active dog. He was a good guard dog, an excellent ratter and a great family dog. He was affectionate, warm and gentle of the most alert and active of dogs, as game as a pebble, an ideal watchman, an unexcelled ratter and all done up in a small package. No dog exceeds him in beauty of outline, and this is enhanced by his sleek coat, with its sheen that the costliest satin does not possess; set off by the rich Tan markings, dainty penciling and thumbing that would puzzle an artist to reproduce. Information is limited on this extinct breed.

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 Black and Tan Terrier suffered from similar ailments as all terriers. He dealt with patella luxation (kneepads floating), skin allergies and eye issues. Because the breed is extinct there is little if any research on the health issues they might have experience before distinction

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

As you would with any terrier of his size 1-2 cups day.

Health issues

The Black and Tan Terrier suffered from similar ailments as all terriers. He dealt with patella luxation (kneepads floating), skin allergies and eye issues.

Exercise and games

The Black and Tan Terrier is in fact a terrier. He was a ratter and he needed intelligent exercise to keep him happy and non-destructive. Activities like barn hunt, agility and fly ball are perfect for this breed. A walk a couple times a day with a time for games is what was needed, and he would love to play ball with kids. They were very cuddly dogs as well.
