Of course with a large dog like this, it is always a good idea to be aware of canine hip dysplasia, particularly because this is a large dog with a deep chest.

This makes him also vulnerable to bloat, a condition where the stomach swells with gas and which can be life threatening. Other things to watch for are ear infections and parasites.

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.

Grooming:

Make your grooming time with this serious, calm canine friend of yours a special bonding time. His coat simply requires a brush twice a week to keep it healthy and shiny.

While bushing him, run your hands over him to make sure there aren’t any unusual lumps. Check inside the floppy ears to make sure they’re not red which could be the start of a painful ear infection.

Look a his nails and trim them if they’ve become too long. Check inside his mouth and make sure there aren’t any black, rotten teeth as this can seriously impact the health of your pet.

Exercise:

Options for exercise will include long walks and a chance to run off his leash. In the back yard it will be to his benefit to throw balls for him to fetch. You can even bring him indoors and play some calm games with him. He should have exercise every single day.

Diet:

Good food is needed for good health. It is always convenient to make use of the commercially manufactured dog foods there are on the market.

You don’t want to feed this to your dog day after day so provide your pet with some tasty home-made food too. Dogs want simplicity and consistency with their diets so they don’t battle with upset stomachs and an unnecessary trip to the vet.

Some home-cooked food twice a week and added to the dry kibble can keep him healthy and happy. Boiled chicken, sweet potatoes, brown rice or pasta, carrots and spinach will be perfect for him. Chop the food up finely and add it into the dry kibble once or twice a week.

Some people even cook it in bulk, refrigerate it and warm up small portions to add to the kibble. Raw meat added in occasionally can also be a good treat. Make sure your pet is never without a constant supply of fresh, cool water.

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.
