Korean Mastiff vs American Staffordshire Terrier - 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 American Staffordshire Terrier is a part of all the confusion surrounding the group of “pit bulls”. The American Staffordshire Terrier is directly related to the English Bull Terrier and English Terrier. The breed of the English Staffordshire Terrier was bred in the early 19th century in the West Midlands. It was not until later that the breed came from Staffordshire. These English Staffordshire Terriers are also the source of contention by breeders who insist it was the Fox Terrier, White English Terrier, Tan and Black Terrier that are the ancestors of the English Staffordshire Terrier.

These terriers (AKA pit bull terrier) came to the United States in the mid 1800’s. By the late 1890’s they were accepted by the United Kennel Club (UKC)as the American Pit Bull Terrier – a new and distinct breed. There were also some that were accepted into the AKC as the Staffordshire Terrier. In England they were still known as the American Staffordshire Terrier. When the AKC accepted the breed in 1936 they were given a new standard, new purpose and new group – the terrier. In 1969 the American Kennel Club recognized these dogs as American Staffordshire Terriers and refused to recognize the American Pit Bull Terrier. The name was changed to move the breed away from its characterization as a bull fighter and to distinguish it from the smaller English Staffordshire Terrier. All American Staffordshire Terriers are directly related to the American Pit Bull Terriers.

You can’t help but stare at the Korean Mastiff because of his strong, muscular neck of loose skin that forms dewlaps. His face is wrinkled and he has a cumbersome, sluggish gait.

He is a large dog standing at anything between 59 to 76cm in height, both male and female. He can weigh between 65 to 74kg. He is noticeable because of his fairly loose fitting coat, which is short and smooth and which is a rich, shiny reddish, orange or brown colour.

The nose of the dog is broad and dark, the ears soft and floppy and he has eyes which are set wide apart.

Temperament:

The Korean Mastiff is reserved with strangers but he is friendly and even tempered with his human family, making an ideal pet.

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.

The American Staffordshire Terrier is a strong, powerful dog – stocky, muscular and graceful. At one point in time the American Staffordshire Terrier and the American Pit Bull Terrier were considered to be the same breed. Even today there are those that make that argument, but they have been recognized outside the AKC as separate breeds. The AKC only recognizes the American Staffordshire Terrier and not the APBT. However – even though there have been decades of separation in breeding the American Staffordshire Terrier and the American Pit Bull Terrier are the very same dogs genetically.

The American Staffordshire Terrier has a broad skull, high set ears and pronounced cheek bones. Their ears should not be cropped by AKC standards and their eyes are far apart, round and dark. With a medium sized muzzle and a heavy muscular back, they are as powerful as they look, if not more so. Most have black noses. The AmStaff has a broad, deep chest with wide set forelegs and compact feet. The tail is short and tapered and it should not be docked.

Your huge Korean Mastiff is a good natured dog who isn’t aggressive. He loves being with his human family and makes a particularly good pet when he has been trained and socialized.

He likes a firm but fair owner who takes a leader-of-the-pack role. In spite of his largeness and sluggishness, he can be quite agile and makes a good watchdog too.

All round, the Korean Mastiff, known as a gentle giant, is capable of making you a splendidly friendly, loving canine companion.

The American Staffordshire Terrier is a loving, gentle dog that wants nothing more than to be with and please his people. Contrary to his reputation as a “killer”, this dog is actually a lover. They are great with children and want to be a part of the family. They even think they are lap dogs, regardless of their size. They are never going to be aggressive toward people and even though they are not one-person dogs, they are loyal, and they are devoted to the family and the “leader of the pack”.

This breed can tell who is their friend and who is not. They are not aggressive, but they will protect their own. They are courageous, confident, attentive, bold and strong-willed. The AmStaff gets along with other dogs most of the time, but they will never back down from a challenge and should never be left unsupervised with another dog. They should not be loose in a neighborhood or at a dog park. No matter how much you trust your American Staffordshire Terrier they can be killers in any fight with another dog.

In addition to this you must socialize and train your AmStaff. You need to be the pack leader and be in control. The AmStaff wants to please you so for a strong leader they will respond positively to positive training. They are intelligent and pick up quickly on what you want them to do. However, they are incredibly strong physically so training them to heel and walk with you obediently is a must. A well trained and exercised American Staffordshire Terrier is a happy dog and a loyal family dog.

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.

For the most part the American Staffordshire Terrier, like most of the “pit bulls” is a hearty, healthy dog. They have a few tendencies that breeders should test for including hip dysplasia, allergies, and heart issues. They can test for Cerebellar ataxia, which has affected the AmStaff with a progressive decline in their ability to control their muscles and coordination.

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.

feed You can feed your American Staffordshire Terrier either commercially purchased food or food you make yourself if the quality is high, nutrition is good, and the amount eaten is determined by the owner. Do not free feed. The AmStaff has the tendency to become obese. Its ok to use treats for training and rewards, as long as its use is controlled.

Health issues

As previously mentioned the American AmStaff Terrier has a tendency toward a few health issues. Hip Dysplasia – this condition causes a lot of pain and disability. It leads to different types of arthritis and degenerative joint disease. Cardiac Issues – Congenital heart disease consists of vessel malformation and lesions.

Allergies

Thyroid Issues

The AmStaff can be susceptible to Autoimmune Thyroiditis. This is a form of hypothyroidism developed by dogs. It is usually seen between 2 and 5 years of age. Continual retesting is recommended.

Cerebellar Ataxia

This is the most dangerous disease possibility that the American Staffordshire Terrier faces. There is a test for this condition which causes the AmStaff to display an inability to control their muscles and a loss of balance, to the point of falling. This is a progressive disease that often leads to euthanasia. The Staffordshire Terrier Club of America suggests that AmStaffs carrying the NCL genes should never be bred.

Exercise and games

The American Staffordshire Terrier is an energetic, and athletic dog that loves to play and needs plenty of exercise. This breed is oriented to people and should never be left alone in the yard all day as a way for her to exercise. She needs you to play with her. If you cannot do this, then you should not own this breed of dog. This breed also loves to play canine sports. They thrive on games like dock diving, agility and obedience competitions. They excel at search and rescue. These are competitive dogs that want nothing more then to please their people.
