With a lifespan of 14 to 16 years, and given the genetic purity of the Kai Ken, you aren't likely to battle with congenital health problems with your dog, but it is always good to be aware of certain minor health issues that he could succumb to.

He can suffer from a few common dog diseases such as progressive retinal atrophy or hip dysplasia.

Progressive Retinal Atrophy:

This is a disease of the eye where there is wasting of certain parts, and in this case the cells of the retina develop abnormally. This can eventually lead to blindness. It’s an inherited disease that can occur in pure- and mixed breeds, and dogs with PRA shouldn’t be used for breeding.

It isn’t a painful condition, and the first symptom usually noticed in a dog is night blindness where you may notice him bumping into things at night and being reluctant to walk around in the dark.

The Cao Fila de Sao Miguel is a dog who enjoys exceptional health. When you do research you see there aren’t really any particular illnesses plaguing this dog, and he can actually live to be 15 years of age. Be aware of some illnesses as they are common among different dog breeds – hip- and elbow dysplasia, bloat, eye diseases such as progressive retinal atrophy and cataracts, heat intolerance and arthritis.

Dog bloat:

This is a dangerous illness that can affect any dog – small or large. This is when the dog’s stomach fills with fluid or gas so that it expands. The stomach then puts pressure on other organs and your dog can have trouble breathing. There is also no blood flow to the heart. Sometimes the stomach of the dog twists and your pet can go into a state of shock. Recognize the symptoms of bloat – a swollen stomach, drooling and wanting to vomit but nothing coming up. Get your dog to the vet immediately.

Abscess:

An abscess can be so painful for your pet often when your dog has a thick coat it could go undetected. If an abscess on your pet doesn’t burst, or even if another abscess appears, a vet must be consulted and a course of antibiotics given.

Ear Infections:

Ear mites, dirt and a build up of wax may cause your dog to scratch at the ear, shake his head or hold it on one side. There may even be a foul-smelling discharge. Your dog will need to have his ears cleaned. Special ear drops can rectify the problem. Remember that hot, red ears will require veterinary attention.

Even though the coat is thick, the Kai Ken will require basic canine care, so a brush twice a week will be enough to keep the coat free of loose hair. He sheds more heavily a couple of times a year and then he will require more brushing.

He has always been used to hunt so he is a dog that will require regular exercise such as walks, hikes, swimming and ball games.

The nails of the dog should be trimmed regularly once they become long as long nails can be hazardous and can hook onto things, causing injury to the nail area.

The ears of the dog should be checked regularly for fleas and ticks, and teeth should also be brushed with canine toothbrush and toothpaste.

The Cao Fila de Sao Miguel is a low maintenance breed and all that will be required for him is that you give him a thorough brushing a couple of times a week.

Diet:

The Cao Fila De Sao Miguel puppy will require four meals of puppy food a day. The adult Cao fila de sao miguel can go down to 1 or 2 meals a day after his 1st birthday.

These days you get some excellent commercially manufactured dog foods and your veterinarian can help you choose one suited to this particular dog breed. Add in some home-made vegetables, rice and meat every now and then. The idea is to make sure your dog is getting in all the minerals and vitamins he needs.

There is evidence showing that dogs who enjoy raw meat every now and then enjoy a number of health benefits. Skin and teeth are improved, your dog has a shinier coat, less allergies,less inflammation and he is more relaxed and amicable. Ensure a constant supply of fresh, cool water in a clean bowl and at all times.
