Koolie 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 Koolie's ancestors were both the smooth coated blue merle Collie as well as the Black and Tan Collie. The dog hails from Australia.

Looking much like the Heeler dog, the Koolie is thought to have got its name from German immigrants to Australia who couldn’t pronounce the name ‘collie’ properly, so the name came out as Koolie. The Koolie of today is a product of a cross between the German Koolie and the Australian Dingo.

The dog has been around for a long time and in 2000, the Koolie Club of Australia was formed. It was in 2004 that the Koolie was recognized by the Australian Sporting Registrar. In May 2006, the Stockdog Committee of the Australian Shepherd Club of America accepted the Koolie as a recognized and accepted herding 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.

Known also as the German Koolie or German Collie, the Koolie is a working- or herding dog standing at between 40 – 60cm in height and weighing up to 24kg.

The Koolie's coat is a merle coat pattern in red or black and possibly with some tan and is mostly short and smooth, though it can be medium length too. Depending on the coat color – red or black – the nose and eyes can be either brown or black, although eye color can also be blue or yellowish.

Temperament:

The Koolie is such a wonderful pet who has some excellent characteristics to his name. He is active, energetic, fun, clever, friendly and playful, but if you have him trained and socialized he becomes even more of a great family pet. He is intelligent too and will require an owner who is steady, firm, fair and consistent. You wouldn't call him an aggressive dog

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.

Many people today like the idea of a ‘wild’ animal as a pet, and the Koolie, with his Dingo ancestry, can be a challenging dog breed to keep. People eventually blame these animals for having a poor temperament – meantime all they are essentially, are high-energy animals.

If you keep a Koolie, it will be better if you were a firm, kind, patient, consistent dog owner who understands the special needs of these kinds of dogs. They’re an energetic, care-free animals who will do better on a large property or farm as he is lively and will need a good deal of exercise.

He is quite capable of being a splendid pet with training and socialization and will settle down well to family life when he is loved and cared for.

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 Koolie is a long-lived dog and there are records of it being able to reach 18 years of age. Because they have a diverse gene pool, you won’t find many genetic problems with this dog.

It is always wise when you’re the owner of a dog, to look out for his health and wellbeing -

Vaccination:

This is to prevent your Koolie picking up fatal diseases such as distemper and parvo-virus. Dogs can be vaccinated from 6 weeks of age for protection.

Parasites:

Working dogs like the Koolie are susceptible to parasites such as tapeworm. Worming of your dog can be included in your vet visit. Dogs with worms may show tell-tale signs such as being pot bellied, very pale gums, anemia and a dull, thinned coat.

A look at his droppings may reveal white segments or worms. Fleas are another kind of parasite and they breed quickly in warm months. Mange is a skin disease caused by small parasitic mites which can actually live inside the hair follicles of dogs. Veterinary treatment will be required.

Heat Stroke:

This is when your pet’s temperature rises out of control. Dogs pant to reduce their body temperature so a dog puffing heavily is putting in extra work to reduce his body temperature.

Never leave you pet in a boiling hot car as the body becomes weak and he has difficulty with breathing. Without immediate treatment, the dog will collapse and die.

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.

Training:

The Koolie is an intelligent dog that will benefit from training and socialization to make him obedient and able to cope in diverse situations.

Exercise:

These dogs show an untiring enthusiasm for exercise and work and wherever you live, you will need to ensure that he gets regular exercise.

Diet:

Only the very best - both home-made and commercially manufactured food - will be good enough for this energetic dog. Good quality food ensures health and longevity. Always see that there is a constant supply of fresh, cool water.

Relaxing Time:

Make sure that your dog has a warm, dry place to sleep inside and that when outside, he has a cool, sheltered spot from the sun.
