Health Problems

ryukyu inu puppies - health problemsThese Japanese dogs are thought to be fairly healthy dogs, but like with most other dogs, you would need to be aware of hip dysplasia, bloat, caner and hypothyroidism.

The Ryukyu Inu, with its 10 to 12 years lifespan, will be prone to minor ailments, but with good care he is not likely to succumb to any of them.


Cataracts have a number of causes in dogs. This disease of the eye can occur at any age, and can develop over weeks or even years.

Cataracts can occur in just one eye or both eyes and a disease such as diabetes can bring on a cataract.

Good nutrition is important for a dog to build a strong immune system, and nutritional supplementation can certainly help to enhance lens health. Cataract surgery can be performed to remove the cataracts.

The Guajae Gae is a healthy dog breed with few genetic problems, if any.

There are always common dog illnesses to watch out for however, and in this spitz-type dog, hypothyroidism is one.

Hypothyroidism in dogs is usually brought on by inflammation of the thyroid gland. Hypothyroidism occurs more often in medium to large dogs as opposed to smaller breeds. The most common signs of low thyroid function in your pet will be loss of fur and excess shedding, weight gain and an inability to tolerate the cold.

Hypothyroid dogs often battle with ear infections as well as skin infections. There are a number of blood tests to confirm a suspected diagnosis of hypothyroidism in your dog.

Caring The Pet

ryukyu inu dogs - caringThe coat of the Ryukya Inu requires brushing twice a week to remove loose hairs. At the same time check your dog over for new lumps and check inside his mouth for bad teeth. Bad teeth can cause lots of pain and toxins within the body. You can also choose to have the teeth seen to and cleaned by your vet.

Provide him with his own warm, dry place to sleep.

Provide him with top quality food. There are some excellent commercially manufactured foods on the market that make a point of ensuring good ingredients in them. Your Ryukya Inu needs good food to ensure longevity and health.

Try to include some home-made food for him which can be simply mixed into the dry kibble twice a week. Boiled chicken, brown rice or pasta and spinach, sweet potatoes and carrots is super tasty and nutritious. This food can all be chopped up, refrigerated and added warmed up and in small portions to your pets dry kibble once or twice a week. Your dog will love it.

Ensure there is always a bowl of fresh, cool water within his reach.

Have him neutered or spayed if you aren’t wanting puppies.

Keep his vaccines up to date against some deadly canine diseases.

Get him to the vet when he is injured, in pain or sick.


He sheds quite a bit and more so in hot weather so he will need to be thoroughly brushed twice a week.


The Guejae Gae is an active dog breed that needs plenty of place to roam freely, and therefore he is a dog breed that will suit life in the country far better than life in the city.

You will need a decent sized yard for him and you should also be prepared to take him on walks and play ball games with him. He is such a social dog and playing with him is something that will strengthen your bond.


As a Spitz type dog, the Guejae Gae has always enjoyed a carnivorous diet. Cheap, poor quality commercially manufactured dog food won’t cut it for these dogs. Home cooked meals with natural ingredients such as chicken, brown rice and vegetables is a good choice as well as adding in some raw meat from time to time.

Always remember when feeding your Guejae Gae that how much your dog eats will depend on his size, age and activity levels. A highly active dog like the Guejae Gae needs wholesome food as well as a constant supply of fresh, cool water.
