History and Origin of the Korean Mastiff 

Little information is available on the Korean Mastiff’s history outside of its native home of Korea. From the little information that is known, it is evident the breed was probably created over 200 years ago. Aside from being called a Korean Mastiff, the breed is known by several other names including Dosa Gae, Mee-Kyun Dosa, and Dosa Inu.

Sources say the breed was developed sometime during the 19th century from breeds such as the Tosa Inu, Dogue de Bordeaux, English Mastiffs, and quite possibly both the Bloodhound and Neapolitan Mastiff. In South Korea, the Korean Mastiff is the largest and heaviest dog available.


The Korean Mastiff has a similar appearance to the Neapolitan Mastiff with the large amounts of wrinkles that they have. The dogs are rather large reaching heights of 24 to 30 inches at the shoulder, and weighing between 145 and 185 pounds. The dogs have a short, very shiny coat that comes in several colors. The coat colors include red, chocolate, and mahogany; a small white patch on the dog’s chest is permitted.

Korean Mastiff Temperament and Personality

The dog’s look should not fool you; although the Korean Mastiffs look intimidating, they are actually a very kind and docile breed. These dogs tend to bond closely with owners and want nothing more than human company. Early socialization is important with this breed, in order for the dog to be good with children and other pets. If socialization is done properly, you will get a good-natured dog that is both protective and gentle.

Due to the large size of the breed, it is important for the dog to understand who the boss is. A Korean Mastiff that sees itself as pack leader will prevent you and your dog from developing a good relationship. Overall, this is a wonderful breed for families because these large dogs like to think they are lap dogs and will “lean” on their favorite people for support.

Health of the Breed

This breed, like many other purebreds, is prone to several health issues. Since the dogs are a larger breed, they are a higher risk of developing hip dysplasia. In addition, these dogs require a strict diet as to not get bloat. Much like the Chow Chow, the Korean Mastiff is prone to several genetic eye conditions such as entropion and cherry eye. Finally, the breed is heavily wrinkled which means that care should be given to the dog’s skin folds to avoid skin infections. The wrinkles can also leave other organs of the dog’s body vulnerable, so these dogs can become expensive to own.

Exercise and Other Care Requirements

The Korean Mastiff is a large breed of dog that grows very rapidly as a puppy; because of this, strict care should be taken when feeding and exercising the puppy. These dogs should be fed the correct amount of food each day (2 to 3 small meals), and should avoid strenuous exercise at too young of an age so the dog’s bones will properly form. These dogs have a moderate energy level, but they are inclined to be lazy. The best option is to give the dog enough space and time to run around freely on its own; this way the dog can decide when it is done.

Diet -Feeding 

Like most giant breeds diet should be formulated for a large to giant breed with moderate to high exercise requirements. You should consult your veterinarian or professional nutritionist for advice on what to feed your  Korean Mastiffs and the correct portion sizes. Their dietary needs will change as they grow from puppyhood to adulthood and senior age. Stay on top of these nutritional requirements, suggested food diet consists of fruit, vegetables, raw chickens whole raw eggs as the shell's are high in natural calcium (never feed cooked!) and a high end kibble, also a joint aid supplement is recommended, not forgetting 10% bones.
