Korean Mastiff vs Japanese Terrier - Breed Comparison

The Japanese Terrier is native to Japan and is a rare pure bred dog. It is believed that the dog comes from Smooth Fox Terriers who arrived way back in the 17th century.

Certainly he looks very much like a regular Fox Terrier. It is thought that these smooth Fox Terriers were then interbred with local, Japanese dogs and used to hunt rats. Gradually he became a lap dog and companion.

Planned breeding of the dog began in 1920, and it was in 1930 that the dog was admitted to the Japanese Kennel Club with a breeding program being started.

Today you will find the Japanese Terrier in his home country and small numbers elsewhere. He was admitted to the United Kennel Club in 2006.

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 Terrier is a small sized dog who stands at 20 – 33cm at the shoulders and weighs in at about 2 to 5kg.

He is a short, smooth haired dog with a tight skin and in colors of white and black. Sometimes you may find a little bit of tan color on the face too as well as 'freckles' around the neck area and legs. The black shading of the coat is essentially found around the head of the dog and also his ears.

His ears are set high on the head and are semi-erect, semi-floppy. The tail has always been traditionally docked, giving the dog a nice compact look but these days it is unfortunately often left long and then its a medium length tail which is thinly covered in short hair. The nose is black and the eye are brown, bright and alert.

Temperament:

Gentle, cheerful, intelligent, loving and loyal are some of the characteristics of the Japanese Terrier. People who have kept him as a pet will vouch for him being a wonderful companion.

He is an active dog, but he still loves to be petted and won’t do well if left alone and not part of his human family. Being a clever dog, he is easy to train, learning easily and quickly. He is quite amusing at times and you can even teach him some tricks.

He gets on well with other pets in the home as well as with children. He is alert and will make a good watchdog, alerting you to an intruder.

Because of the Japanese Terrier’s small size and sensitive nature, this breed needs a calm owner and a quiet household. It is not recommended for boisterous households.

He is looked upon as a gentle giant, being an oversized playmate for children and he also tolerates other pets in the home.

He isn't an overly energetic dog, but that doesn't mean he shouldn't be exercised. He will need long walks to avoid him putting on weight.

As a pet of yours, the Japanese Terrier is an animated, contented little dog. He loves playing games and gets on well with children who aren't rough and disrespectful of him.

The Japanese Terrier has no particular health issues and has a lifespan of 12 – 15 years if looked after well.

There are always one or two illnesses to watch out for such as eye- and ear infections. Some dogs also develop conditions such as Patella Luxation. This happens when your dog's kneecap is dislocated. It can only be returned to its normal position when certain muscles in the back legs are relaxed and lengthened.

With this condition, your dog holds up one of his hind legs. This condition is more prevalent in small dog breeds.

Treat your big Mastiff dog like the wonderful fur-child he is and make sure your attend to all his medical needs to avoid pain and discomfort for him.

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.

The Japanese Terrier is an active dog and will require exercise every day. He’ll love to join you on your walks or have ball games in your garden. He can adapt to life in the city or in the country but will always need to have good exercise.

Grooming:

The Japanese Terrier is a medium shedder and you want to be sure then to brush him twice a week to get rid of all those loose hairs.

Diet:

The Japanese Terriers will require the best commercially manufactured dog food, and instead of one large meal a day, rather feed him 2 smaller meals. You can mix some tasty home-made food into his dry kibble from time to time. Excellent home-made food would be something like cooked chicken, brown rice or pasta and some vegetables.

If you can, try to also include some raw meat occasionally. If you’re in any doubt as to how to feed your Japanese Terrier so that he remains healthy, speak to your veterinarian.

Your dog should never ever be without a continuous supply of fresh, cool drinking water.

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.
