This is of particular importance to breeders so as to prevent the parent dogs passing bad genetic conditions to the puppies.

Hip Dysplasia:

This is a common skeletal disease where the dog’s hip joints don’t develop properly. It can be terribly painful for your pet to get around. It’s a genetic condition and while it is more prevalent in big dogs, any breeds are susceptible.

Your dog will battle along with painful joints and sometimes his hind-end will be lame. You’ll notice that once lying down, he battles to get up again. Fortunately vets are well acquainted with this ailment and they have different options to treat and manage it.

Cataracts:

Cataracts in your dog come about from a disease process which affects the lens of the eye. The eye loses its transparency and impairs vision. There are some instances where cataracts can cause blindness. You’ll see a whitish gray area in your pets eye. The most common cause of cataracts is genetics. Get your pet to the vet who will do certain tests to evaluate the eyes and make a recommendation.

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.

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.

You have to be careful about cleaning your pet ears if you don’t know how, as it could damage the ears. Your vet can always advise you on how this is done.
