Korean dog.

There are few kinds of dogs which makes Koreans proud are proud of Korean.
One of them is 진도개(jin-do-ge).
진도(jin-do) is a name of an island and 개(ge) means dog.
These dogs live in an island, 진돗개 are confined to stay in the island only.
And other species dogs are prohibited to enter 진도-island.
Nobody can bring their pet dog to the island. That is a law.
If other dogs were found in 진도-island then they will be killed that will be death by officers who preserve 진돗개’s descent.
진도개 is the most clever though there are many clever dogs in the world.
However one of 진돗개’s characteristics is they serve only one master through their lifetime.
So 진돗개 can not be used as war dogs. If a soldier who trained the dog were discharged from military service and went his home, the trained dog would not obey other soldiers and not eat meal with the new master. waiting master who is considered by dog.
Because of the above characteristics, changing masters is a problem with 진돗개.
If you want to live with 진돗개, you must bring them when they are baby.
We can buy 진돗개 at entrance of 진도-island.
