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 Biewer is, or was, a piebald Yorkie caused by a recessive gene in a breeding of two Yorkshire Terriers. On Jan 20, 1984 a piebald Yorkshire puppy was born in Hunsruck, Germany to Gertrud and Werner Biewer. The puppy was considered beautiful and the Biewer’s fell in love with it and began a process od selective breeding in an effort to breed piebald Yorkies. Based on a friend’s suggestion, they named this group of puppies, “Biewer Yorkshire Terrier a la Pom Pon”. By 1989 the Allgemeiner Club der Hundefreunde Deurschland (ACH) officially recognized the Biewer Yorkie as a separate breed. Today they are recognized world wide as two separate breeds.
Today there have been genetic studies done that have declared the Biewer Terrier to be a separate and distinct breed from the Yorkshire Terrier, not simply tricolored Yorkies. The BTCA (Biewer Terrier Club of America) changed the name and standard to an original one for the Biewer Terrier. Mrs. Biewer has accepted and signed this revised standard and it is the only one she has accepted. This new standard allows the Biewer Terrier to have a black coat and an undocked tail. In 2014 with the new standard the American Kennel Club Foundation Stock Service (ACK/FSS) accepted the Biewer Terrier. Some breeders still want the breed called the Biewer Yorkshire a la Pom Pon, but Mrs. Biewer has objected to this, insisting the dog is a terrier. The Biewer Breed Club of America (BBCA) insists on the breeding of Biewers only to other Biewers. This is opposed by others who are importing Biewers and breeding them with Yorkies. The result is not recognized as a purebred dog. BBCA breeders do not engage in this type of cross breeding or condone them. The BBCA breeds only dogs that meet the standard set by the BTCA.
The first two Biewers were imported to the States in 2003 by Donna Hall. They made history in 2003, when they were accepted by the IABCA (International All Breed Canine Association) and entered their first dog show. Today they are shown in rare breed dog shows around the world. Today there are two standards in operation for the Biewer as the American Biewer and the North American Kennel Club continue to follow the German standard while the BBCA follow the revised standard approved by Mrs. Biewer.
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.
This long-haired terrier is a neat and compact toy dog. Their hair should be as long as their body is high and hang straight from the bottom of his skull to the end of his tail which is carried upward. He is a well proportioned and powerful little dog. He has no undercoat, but his overcoat is very much like human hair and should be combed. The head is a signature of the Biewer, covered with symmetrical gold, white and blue/black hair. They have flat, small heads and a black nose with an average muzzle. They have intelligent, dark, medium sized eyes and small ears shaped as a V and standing erect. All four legs are straight, and the hips are well formed. They have round feet and an undocked tail.
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 Biewer Terrier loves to be loved and he returns it in volumes. This is a dedicated, fun loving and charming little dog that you can carry around. They are loyal and friendly, athletic and alert. They are barkers when they need to be, but they are not “yappy dogs”. They love toys so make sure they have plenty. They will carry them wherever they go.
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 Biewer Terrier is not a cross breed or hybrid and so does have some of the very serious health issues of the Yorkshire Terrier including the bane of small dogs with liver shunts. Liver shunts are fatal if they are not treated. The breed does have sensitive stomach issues as well. They face other small dog issues like floating patella’s, ear and skin infections. Other than this the Biewer Terrier is a very healthy breed.
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.
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.
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.
As previously mentioned the Biewer Terrier has a very sensitive stomach and intestinal system. He should be fed low protein dry dog food. Watch for signs of food allergies such as scratching or chewing on his feet. Feed 2-3 times a day but the Biewer Terrier is one of the few dogs that you can safely free feed unless you notice substantial gaining of weight.
Health issues are few as mentioned previously. However, make sure your Briewer’s ears are free of debris and wax, make sure their teeth are brushed and they show no signs of allergies. Along with liver shunts, sensitive intestinal and stomach issues and floating patellas, these are the other minor issues that might occur. Watch for diarrhea and off colored stools.
The Biewer Terrier is an active dog that needs regular exercise and walks. He is a speed demon as his ancestor the Yorkie is and needs an outlet for running as well as daily walks. They love to run, and they love to play. They do great in agility but love adventures. They are smart and love to learn tricks. Since they love hunting vermin they would also excel at Barn Hunt.
