Polish Lowland Sheepdog 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.

Hailing from Poland, the Polish Lowland Sheepdog is believed to have descended from herding dogs as well as the Puli and Tibetan Terrier.

Later these dogs were bred with local Scottish dogs to bring about Scottish herding dogs, the Bearded Collie. The dog was accepted by the Federation Cynologique Internationale in 1959. In 2001, the American Kennel Club recognized the Polish Lowland Sheepdog as a breed in the Herding Group.

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.

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 PON is an independent, self-willed dog but he can also be entertaining and amusing. He is a social, friendly dog but for many people, his long hair and grooming requirement might prove to be a bit of a handful.

Your dog is energetic, cheerful and playful and when he isn’t around, it will be like some sunshine has gone out of your life. He is faithful and loving towards his human family but is aloof towards strangers. Bring one of these dogs into your home and you’re guaranteed to have a remarkable friend and pet for many years.

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.

These dogs are generally healthy and the dog’s life expectancy is about 12 years. Nonetheless there are some problems to be aware of. For instance, with this dog, hip dysplasia is a real problem.

The Orthopedic Foundation of America evaluated the hip X-rays of hundreds of these dogs and found a large percentage were dysplastic.

Hereditary eye disease can also occur with this dog. Macular degeneration is a common eye disorder that can cause central vision loss. Many genetic abnormalities can cause degeneration of the image forming part of the eye. Unfortunately these conditions can result in total blindness. Parts of the retina can also degenerate with age.

Skin allergies are also an ever present threat with your dog. Itchiness and pain can be a nightmare for your pet and scratching and licking brings no relief – just aggravates the condition. You will certainly need to get your pet to the vet as skin allergies and skin diseases can make your beloved canine miserable.

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.

Your Polish Lowland Sheepdog is like a big Bear and his long, shaggy coat will require regular brushing, otherwise it could become full of burrs and grass.

Many people prefer to take their dogs to a grooming parlor where the hair is cut, the nails trimmed, the teeth cleaned and the ears checked.

Provide your Sheepdog with a nice warm, dry cozy spot that is his and where he can quietly retreat.

If your Polish Lowland Sheepdog spends time outdoors, make sure he has access to both shade, sun and shelter in case it rains. There must always be a bowl of fresh water outdoors too.

Diet:

It is better to give your adult Polish Lowland Sheepdog 2 smaller helpings of food as opposed to one big bowl. Puppies will need 4 bowls of food a day. Two bowls will ensure your dog doesn’t gobble up his food and create digestive problems and bloat.

High-quality dry dog food will provide a balanced diet, but you want to make it a little more delicious for him occasionally by mixing in chopped up boiled chicken, brown rice, sweet potatoes, carrots and spinach. Just a tad of raw meat occasionally can also be of huge benefit.

Fresh, cool water should always be available around the clock. Be sure to keep his food and water dishes clean.

Have your dogs spayed or neutered if you don’t want them to have puppies.
