Heart Problems:

Dogs can also suffer from heart disease, especially when there is an obstruction to the flow of blood to the brain which can cause your pet to collapse. Veterinary attention must be sought without delay.

Kidney Failure:

Frequent passing of water can be indicative of a kidney problem. Veterinary advice will be needed.

Grooming:

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.

Companionship is important for the Cao de Fila da Terceira, and if you don’t have another dog in the home, as a pack animal, your dog will rely on you for being an active part of his life. A dog that is well treated becomes thoroughly loyal to his owner.

Your vet will know that protein for instance, is essential for your dog. The vet will also speak to you about how to feed a puppy, an adult dog, a pregnant female dog and also feeding your senior dog. Your vet will also explain the hazards of overfeeding and how raw meat also needs to be included in your pet’s diet.

Fresh, cool water is your pet’s life-blood and should be available to your dog night and day. Every dog can benefit too from taking a daily supplement rich in omega-3 fatty acid.

Grooming:

The grooming of your pet will depend on the breed. The Cão de Fila da Terceira has a short coat so he will be easy to maintain. Brush him twice a week to remove loose hairs.

Areas which also need checking daily are the eyes to see that there is no discharge. It is also important to inspect the ears as there should be no build-up of wax inside the ear. Toenails also need attention and should be clipped if they grow long from the pet not walking on hard surfaces.
