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.

Grooming:

The Cao de Castro Laboreiro has a short coat which requires minimal grooming. Brushing him twice a week to rid him of loose hairs will suffice.

Nail clipping as well as ear- and teeth cleaning are other routine maintenance procedures for your pet.

Diet:

The food you give your pet must be well-balanced and have protein and carbohydrates. If you want his skin and hair to remain healthy, vitamins, fatty acids and minerals will also be needed.

Boneless chicken and fish, brown rice and vegetables can be a good choice as well as some of the top quality commercially manufactured foods. An active dog will always need a higher protein content and therefore including raw meat into the diet is imperative – not every day as it can be very expensive, but every other day.

Remember that bones can be dangerous as they can splinter and cause your pet internal damage. Fresh, cool water must be available at all times.
