Korean Mastiff Breed and Health information


The Korean Mastiff is a rare breed. The Korean Mastiff was born in South Korea and is a large dog with a long past.

Korean Dosa Mastiff can also be called Mee Kyun Dosa.

The origins of the Korean Mastiff can be traced back in the 1900s, when several giant guard dog breeds were bred to create a powerful and striking dog. Dogue de Bordeaux and Bloodhounds are also part of the Korean Mastiff’s pedigree.


Mastiffs can be very large and are not recommended for those who don’t have a spacious home and property. Their height ranges between 150 and 200 lbs for small females and nearly 200 for large males.

Their hair is usually short and thin. They are available in many solid colors, but mainly shades of brown. Their ears are long and droopy.

Their prominent feature, particularly on the face, is their prominent wrinkles.


Although Mastiffs are generally friendly and docile companion dogs, it’s important that they are well socialized and trained. Because their original purpose was to guard and protect, many Korean Mastiffs are suspicious of strangers.

You should expose them to different people and social situations as puppies. Otherwise, they may become reactive in adulthood. They are friendly and outgoing puppies and love to greet people and lick their faces.

When the dogs reach 6-10 months of age, their outgoing temperament changes. It is important that they have plenty of socialization opportunities during this period. Positive experiences with other dogs should be provided at least twice a week. To keep everyone safe, you should always use a leash. Your Mastiff must be wearing a collar all the time.

The Korean Mastiff is used

Originally, the Korean Mastiff was bred to be a guard dog. His original purpose was to protect his owner’s property from intruders. The Korean Mastiff’s imposing stature, often paired with a tactical neck, is ideal for this.

He was an independent worker and had to be able to tell the difference between friend and foe, and deal with any threats.

The Korean Mastiff’s modern use is very different from that of many other working dogs. They aren’t common outside of South Korea but they are still used in many ways in their country.

Owners often bring their Mastiffs to dog shows, while others take them on hiking and camping trips. Some even use them for trick dogs.

You will need to seperate any pets you already have. Many accidents occur because dog owners are too trusting their dogs too quickly. This breed is not meant to be gentle and sweet like the Cavachon. A Korean Mastiff can be a strong and determined dog that will pursue smaller animals.

As with small animals, you should never leave a Mastiff with children under five years old. This is not because your Mastiff might see them as prey, though this could happen in very rare situations. It’s more because these large dogs can hurt children even when they don’t intend to.

Respect must be taught to children about your Korean Mastiff. This is what it means:

  • Do not chase the dog
  • No dog teasing
  • You must not take food, bones, or toys away from your dog.
  • You can’t corner the dog
  • There are no “human” games that can be played with dogs, such as dress-up.

Your Mastiff will be a great friend to your kids if they treat him with respect.
