Kyi-Leo 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 Kyi-Leo first came about in the 1950s in San Francisco, USA, with the crossing of two dog breeds – the Lhasa Apso and the Maltese.

Because this is a mixed-breed dog, it isn’t recognized by the American Kennel Club, but it is recognized by some of the other dog associations such as the American Rare Breed Association or ARBA as it is known. Today the dog is looked upon as a designer breed.

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 Kyi-Leo is a small dog standing at 20 – 30cm in height and weighing in the region of 4 – 6kg.

He has a long, silky coat which is essentially black and white or grey/silver and white or even gold and white. He has frail legs which can become injured or broken in vigorous rough and tumble games.

Temperament:

You can certainly describe the Kyi-Leo as a sweet, quiet, non-aggessive playful dog, and for anyone who wants a splendid pet and companion, this dog makes a great family pet and he won’t cost you an arm and a leg to feed either.

He also has an acute sense of hearing and this turns him into an excellent ‘alarm’ watch-dog. It is also a dog, that while he will love to join you on a walk, he isn’t a dog that is going to demand a lot of exercise.

He responds well to his human family, is easy-going and gentle, tending to be cautious around strangers. You can trust him to be an awesome playmate for children. In this instance, it’s the children who should be warned when playing with a dog like this as, because of his fragile build, he could easily be injured by children who haven’t been taught to respect animals.

Even though he is such an amicable pet, it will still be of benefit to you and him to have him trained and socialized. Then he responds well to basic commands such as sit, stay and lie-down.

Dogs who spend time with their family, pick up on the ‘culture’ of the family and they learn how to behave. Dogs who are left on their own and never socialized can become nervous and aggressive towards people as they never got to learn how to behave – they weren’t socialized.

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 Kyi-Leo is everything you want in a family companion – active, playful, loving, gentle, happy and balanced.

He loves his human family but tends to be a little bit wary around strangers, gradually warming to them.

He may be small, but he is robust and alert, and he is also capable of making you a good watchdog.

The Kyi-Leo is an all-round great little pet to have.

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.

Your Kyi-Leo is such a feisty, robust little dog who is not likely to cost you much in terms of health care. With his frail legs, it is a good thing to know that you need to be careful with him in terms of back-and joint problems.

There are actually knee joint issues which are fairly common in small dogs, one of which is patellar luxation.

Patellar Luxation:

This is where the kneecap pops out of the thighbone, causing the dog to skip or hop. Some joint issues are genetic and may require surgery. Make sure to keep your pet’s weight under control to remove additional stress on the joints.

Pancreatitis:

This is another dog illness you want to be careful with. Acute pancreatitis -inflammation - is when the condition comes on suddenly while chronic pancreatitis is when pancreatitis occurs over a period of time.

With acute pancreatitis in dogs you’ll see symptoms such as vomiting, abdominal pain, tremors and reluctance to eat. Pancreatitis can be brought on by too much fat, especially rancid fat, some anti-biotics, a low protein diet or a sickness such as diabetes.

If you suspect pancreatitis in your dog, get him as quickly as possible to the vet.

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 and Interaction:

The Kyi-Leo doesn’t require vigorous exercising. One walk a day will keep them happy. There are pet owners who believe dogs can be permanently outside dogs where they can do their own exercise.

Everybody who knows dogs, knows they are social creatures who will simply lie at your backdoor just waiting for some response from their beloved human family. Every dog, regardless of breed or size, needs exercise and interaction with their humans every day.

Dogs left alone in the yard day after day are loney, frustrated and bored, and when they start digging or barking, irresponsible owners will ill treat them. These kind of people should never own a dog.

Diet:

The Kyi-Leo has a sensitive stomach so he’ll need good quality food to avoid digestive problems. Ideally home-cooked food such as softly boiled chicken, brown rice and raw or cooked vegetables added into top quality kibble is the preferred diet.

Fresh, cool water needs to be constantly available.

Grooming:

Brush the long, silky coat at least twice a week to ensure it remains free of knotting. Brushing keeps the coat shiny too.

As a long eared dog, ears should be checked and cleaned regularly too. Air doesn’t reach the inside of their ears and the warm dampness in the ears are a breeding place for infection.

Nails should also be trimmed when they become long because left uncut they can hook onto things causing injury ad pain.

Small dogs are more prone to tartar formation and loss of teeth. You’ll notice that something isn’t right because your lively little dog will be lethargic, he may not want to eat his food and his face may be swollen. When you suspect dental problems, get him to the vet.
