Korean Mastiff vs Japanese Chin - Breed Comparison

This large breed dog is also known as the Mee Kyun Dosa. In spite of his huge size, he isn’t aggressive at all and is bred to be a companion dog.

He was originally developed to be a working dog. The dog was developed in the late 1800’s from European and Asian working breeds. Those interested in dog breeds suspected that a crossing of the Japanese Tosa-Inu with the Neapolitan Mastiff and the Dogue de Bordeaux brought about the breed. They also thought that the Saint Bernard and English Mastiff were brought in later on as well.

These large molosser dogs have been developed through years of inbreeding. It is one of the biggest dogs in Korea.

The Japanese Chin, also known as the Japanese Spaniel, has always been known for thousands of years as a dog with strong companion characteristics.

The first Japanese Chin was brought to America in 1882. The toy breed was recognized by the American Kennel Club in 1888, as a Japanese Spaniel. The AKC changed the breed name to the Japanese Chin in 1977.

Cherry Eye:

Cherry eye is a fairly common health issue with this breed. It affects the tear gland of the third eyelid, and if left untreated, can lead to ongoing eye problems.

All dogs have a third eyelid, as well as two tear producing glands to lubricate the eyes. Its an important protective component to eye health in dogs. When the connective tissue that holds the gland in place is damaged or weak, there is a red protrusion of the gland from the lower eye. This is a congenital disorder. Don’t ignore it, but get your pet to the vet so you can catch it early.

Bloat:

Canine bloat, known as gastric dilatation and volvulus can be a killer disease for your pet, more so with deep-chested, large breeds.

Gas accumulation is known as bloat, and its the accumulation of gas which can cause the stomach to rotate. A dog can go into shock from bloat. The reason for this is that the stomach expands, putting pressure on veins. Blood can’t flow as it should and the blood supply gets cut off to the stomach.

Your dog could be vomiting, restless, the stomach hard and bloated or he may be drooling. Dogs who gobble their food down and eat just one large meal a day have an increased susceptibility to GDV than other dogs.

The wrong ingredients of a dog’s diet can also contribute to bloat. High quality food and feeding your pet smaller meals can help.

There are a few health issues with your Japanese Chin that are worth knowing about such as hypoglycemia, cataracts and heart murmurs. Allergies and dental issues also need to be checked.

Dog breeds with the flattened face always battle with dental-, eye and breathing problems. With good care however, your Japanese Chin can reach anything from 10 – 12 years of age.

Heart Murmurs:

Murmurs come about because of a disturbance in the blood flow and which can produce an audible noise. If your dog's murmur is associated with structural heart disease, your dog may display signs of congestive heart failure and he'll be weak for instance and be coughing.

When your dog gets to the vet, the course of treatment will be determined on the type of heart murmur. Luckily puppies with low grade murmurs often grow out of it but if you have an adult dog, routine diagnostic imaging may be recommended by your vet.

Grooming:

A Korean Mastiff is an easy dog to groom with his short smooth coat. He is a moderate shedder so a brush twice a week will be sufficient to maintain the shiny, smooth condition of his coat.

Because the dog has lots of skin and folds, these folds will need to be washed and kept clean as grime can collect.

While you're busy attending to his skin check his nails too and check inside and outside his ears for signs of redness and irritation.

Diet:

Puppies use up more energy than mature adults, requiring a diet of good quality protein. Dogs that have been spayed or neutered will require less calories as will senior dogs.

Korean Mastiffs require high quality nutrition, and if its dry kibble, make sure its the best brand. Mix in some home-made food such as cooked chicken, brown rice and vegetables from time to time as well as some raw meat occasionally.

Protein and fat from good sources are top ingredients for your Korean Mastiff. Avoid food with allergens such as corn and wheat, sweeteners, preservatives and colorants.

Make sure your large pet has constant access to fresh water.

Grooming:

The Japanese Chin has a single coat, and a brush once or twice a week will keep the coat silky and untangled.

Check his ears for dirt and wax and try to wipe inside the ears, being very, very careful not to go deep into the ear to avoid damage.

Clip his nails and brush his teeth as small dogs are more prone to dental disease. Periodontal disease is preventable with dental cleaning. Dental disease starts when plaque sticks to the surface of the teeth. It hardens, spreads under the gum line and cause tissue damage. It also damages the immune system.

Exercise:

The Japanese Chin is an energetic dog and loves a game and a walk. It isn't the kind of dog that you will take on your hikes or swimming as it tends to huff and puff after a while from too much exercise, and more specifically in hot weather.

Diet:

Dog experts say that a grain-free food is best for this kind of dog. Kibble which comes with lean protein and with plenty of vitamins and minerals such as taurine and carnitine is recommended. They are good for the joints, coat, heart and eyes. Japanese Chins can be prone to heart- and eye problems and kibble rich in omega 3 fatty acids will be good for the Chin for many excellent reasons.

If you're in any way uncertain about what to feed your Japanese Chin, speak to your vet as the type of food you feed your pet will determine how healthy he will be. Always ensure he has access to fresh, cool water.
