Gull Dong vs Gran Mastin de Borinquen - 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 Gull Dong dog is thought to come from British Colonial India during the 1900's. The area later became known as Pakistan, and this is where the dog originated from.

Known also as the Bully Gull Terr, the dog came about by crossing Bully Kutta (Pakistani Mastiff) with a pure bred Gull Terr. The breeders wanted a dog that had the best features and characteristics of both the 2 dog breeds.

They were looking for particular characteristics such as size, strength and speed. This is a rare dog breed and he isn’t associated with any kennels or clubs, so not many records have been kept regarding their origin and development.

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.

Temperament:

After training, he will require a strong, firm and consistent owner. He is fairly suspicious of strangers and won't take kindly to anyone who tries to come onto his properly. He is a dominant, aggressive dog and while he is a loyal, loving pet with his human family, he isn't an ideal dog to have with small children in the home.

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 Gull is a fairly healthy dog, and with good care he can reach 10, 11 or 12 years of age.

Deafness:

If you choose to own a white one, you will know that he is susceptible to deafness and skin problems. White coated dogs battle with deafness, and the reason for this is that they carry the piebald gene. The piebald gene is a result of the absence of melanocytes – those cells which create pigment.

The ability to hear comes from a layer of cells within the inner ear which come from the same stem cell source. Without this stem cell, the dog isn't able to make this specialized layer of hearing cells.

Hip Dysplasia:

With hip dysplasia, the head of the thigh bone doesn’t fit properly into the hip socket, resulting in the bone wearing away and arthritis settling in. Your dog can experience pain and stiffness and he can become lame. You'll notice he is no longer enthusiastic to join in with games and exercise.

Hip dysplasia can be managed with medication while some dog owners, if they can afford it, turn to surgery which can be very costly.

Bloat:

He is a deep chested dog and this means you need to be aware of the risks associated with bloat, an emergency gastrointestinal syndrome which can be life threatening and where your dogs stomach becomes hard and bloated.

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.

Exercise:

Plenty of room to run around in is important for the Gull Dong as he is a working breed who is used to having a job to do. You will certainly need to take him on walks or play rope- and ball games with him.

Grooming:

The Gull will require brushing twice a week as he is a short haired dog and an average shedder.

Diet:

This is a large energetic dog and you will need to feed him a high quality food specially for large, energetic dogs. He needs his full quota of minerals and vitamins in his food. Provide him with homemade food such as cooked chicken, rice and vegetables and some raw meat from time to time. Never leave him without a constant supply of fresh, cool drinking water.
