During the cold war, the Soviet Union developed the Black Russian Terrier as a working military dog. During the early 1950’s, the Red Star Kennel developed this breed and in 2004 by the American Kennel Club. The Black Russian Terrier is not really a terrier at all, but a mid-sized working dog used for hunting and guarding or as a pet. The Red Star Kennel is thought to have developed the BRT using a wide variety of breeds – as many as seventeen – including breeds like the Newfoundland, the Rottweiler, the Caucasian Shepard Dog and a Giant Shepard and an Airedale. So, you can see the wide variety and several more breeds were added. The Red Star Kennel in Moscow was owned by the state and they developed the BRT for specific working conditions and not for appearance. They did not really care how it looked except that it had to be black. In 1957 the state allowed a few puppies to be sold to non-military breeders. These breeders began to breed the Black Russian Terrier for appearance as well as function.
As these breeders worked with the dogs, they spread the breed throughout Russia and into Finland, Poland, Hungary, Germany, Czechoslovakia and Germany. From there they spread to Australia, Canada and the United States. The breed standard was developed in 1958 and by 1996 an updated version of the standard was developed to reflect the dog we see today. In 1996 the United Kingdom also got their first introduction to the breed. They are still rare outside of Russian or previous Soviet Union states.
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.
A little larger than a mid-sized dog, the Black Russian Terrier is strong, powerful, stable and alert. His head is block shaped and has a broad skull. The muzzle is square with a beard and mustache. A black, large nose and full black lips are matched with powerful and large jaws. He has a scissor bite and his ears should be triangles with rounded apexes. They have very large paws that are bear-like in appearance with thick black pads. They are also covered with hair. Their legs are muscular, powerful and strong. They have a cropped tail.
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.
The Black Russian Terrier is a working dog and he is confident, calm, self-assured and confident. He is responsive and intelligent, protective and fearless, loyal and aloof. He is not welcoming to strangers. If socialized well, he is enough of an independent thinker to be able to decide on his own who or what poses a threat to his family and what doesn’t. They get bored quickly because they are so smart. Keep him stimulated. These are strong, athletic dogs who will love to run with you, jog along side your bike, hike the mountain or just walk with you. Whatever your form of exercise is, the Black Russian Terrier can adapt to it. They also have a strong prey drive so don’t trust them with animals they do not know. They are ok with cats and dogs that they grow up with. They love to play with kids but be careful they don’t unintentionally knock the little ones down.
The Black Russian Terrier matures later than other dogs. Treat the puppy the way you want the adult dog to be. If you don’t want a large dog on your bed don’t let the puppy sleep on the bed.
