Gran Mastin de Borinquen vs Chow Chow - 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.

Northern China is the original home of the Chow Chow. In that region of China, the breed was known as the Songshi Quan – “the puffy-lion” dog. They have also been known in China as the “Dog of the Tang Empire” or the Tang Quan. The Chow is believed to be an ancient breed that the Foo Dog, or stone dog guardians of Buddhist palaces and temples, is modeled after. It is one of the most ancient of dog breeds that are still around today.

It is believed that they have existed for around 2000 years or perhaps even as far back as 3000 years, starting out in Mongolia and migrating to China. The ancientness of the Chow Chow has been validated through DNA testing. In China all those centuries ago, the Chow Chow was born to be a working dog. They hunted, herded, guarded and pulled carts. They went on quests with the Mongolian armies when China was invaded, as well as when the Mongolians invaded the Middle East and Europe later on.

Today’s Canadian Kennel Club has about 350 Chows registered while the AKC gets 10,000 new registrations every year.

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 Chow really does look like a small lion with a black tongue. The dog is sturdy and square with erect, small ears on a broad skull. They have a very dense double coat. Their eyes are deep set and look like almonds, while they all have that very distinctive purple or black tongue. Their lips are also distinctive with their blue color. The nose is black, but some Chows might have a blue nose. The tail is curly.

These are medium size dogs when it comes to height and weight, but they are powerfully built for their size. Their power is in their compact body holding the energy and strength of a much larger dog. Its hind legs are almost entirely straight, unusual for any dog. They get their lion appearance from the huge ruff that stands behind their heads. Their chest is broad and deep.

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.

Loyal and true to their family and those they know; the Chow Chow is a little standoffish with strangers. They are very protective and usually attach themselves to one or two people. They are intelligent but stubborn, which can affect your training with them. They need to respect their people and Chows respect hose who take care of them. They can be aggressive toward dogs of their same sex especially if those dogs are the same breed as well.

They are known to be very clean and many have compared them to cats in that regard. They appear to be dignified and refined. They are usually very quiet but very adaptable dogs.

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.

Although an ancient breed that obviously has survived many centuries of trials, the Cho Chow of today is prone to several different health conditions. These include:

Eyelid Entropion

This condition can require surgery to keep the turning eyelid from injuring the eye ball.

Hip Dysplasia

This can cause lameness and arthritis.

Elbow Dysplasia

This can cause lameness and arthritis.

Stomach Cancer

Ear Infections

Make sure you keep the ears clean and keep an eye on them.

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.

Don’t overfeed a Chow Chow as they are hard workers and big eaters. Feed them at least twice a day.

Health issues

Additional health issues include:

Glaucoma

This eye disease can lead to blindness if not checked and treated.

Juvenile Cataracts

These can be removed from an adolescent puppy.

Lymphoma

Again, the Chow is susceptible to cancer.

Diabetes

Can lead to heart or kidney problems if left untreated.

Hot Spots/Allergies/Melanoma

Keep a close eye on your Chow Chow skin.

Exercise and games

The Chow Chow was developed as working dog, but today’s version is more laid back and doesn’t need excessive exercise. Daily walks will suffice. They live very happily in the city if walked regularly. They are not really a competitive breed outside of obedience and confirmation. They are seldom seen in sports like agility or frisbee.
