Some of the illnesses your Kishu can get will be easily treatable, while others may be life-threatening and require surgery.

The health of your dog will depend a lot on the food you provide it with as well as your lifestyle. Common dog health problems can range from typical eye- and ear infections to bloat, hip dysplasia and cancers.

Hypothyroidism:

The thyroid gland doesn’t produce enough thyroid hormone which can lead to other health problems such as tiredness and weight gain. A daily thyroid pill from the vet can help sort this issue out.

Arthritis:

This is a common health problem, seen more in older dogs. Your once active dog will move around slower and battle to stand up after lying down.

Arthritis can’t be cured but you can alleviate the pain and suffering. Your vet will tell you that diet and nutrition are important factors to ward off arthritis in the first place.

If your dog has arthritis and is in pain, get him to your vet who can prescribe medications to alleviate the symptoms.

Kennel Cough:

This is a respiratory infection which can be transmitted from one dog to another. You’ll notice coughing, tiredness, runny nose and watery eyes and loss of appetite. Take him to your vet who will know what to do to speed up recovery for your pet.

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.

Grooming:

The Kishu will need to be brushed twice a week to keep the coat free of dust and loose hairs. Their ears should be checked regularly too for wax build up and dirt as ear infections are a common dog illness.

Their nails should also be trimmed regularly. Take him regularly to have his teeth cleaned because dental problems can put his entire body at risk for disease.

Exercise:

The Kishu needs a good sized garden to roam. He is best suited to country life because he needs regular exercise. If he lives in the city, put him on a leash and take him for walks.

Diet:

Apart from exercise, good food is imperative as nutritious food contributes to longevity. Top quality food and the right size portions can ensure lean, energetic, happy, healthy dogs.

Take trouble to understand the ingredients listed on the commercial dog food packaging. Generally the low quality, processed commercial foods are inflammatory.

Even if you go for the top brand kibble, don’t just provide your pet with dry kibble night after night. Mix in some cooked chicken, brown rice and vegetables.

Remember too, that fresh whole foods such as vegetables have live enzymes and are packed full of fiber which is so necessary for digestion. A good diet with fresh, cool water is guaranteed to provide an excellent dimension to your pet’s health.
