The Jindo dog is a native Korean breed of dog bred in Jindo-gun, Jeollanam-do. Males of the species are about 50-55cm long, females about 45-50cm. From the front, its head and face is octagonal. It has ears that point a little forward and rise stiffly; triangular eyes; and a dark-yellow or grey coat. Their noses are mostly dark, although they may occasionally be a pale red. Jindo dogs have a bold yet meek nature, a keen nose coupled with good hearing, and a strong sense of homing, making them suitable for hunting. They are also reputed to be faithful and smart, and hence are suitable as pets or house dogs. It is presumed that the Jindo dogs were introduced to Korea when a trade ship from China (Southern Song) was wrecked in the waters off Jindo Island during the Three Kingdoms Period. There is also a saying that during the resistance of the Sambyeolcho (1270-1273, Three Elite Patrols) against Mongol soldiers, Jindo dogs were used by the military. In addition, it is said that the breed was introduced to protect the army’s horse ranches during the Joseon Period. However, the full history surrounding Jindo dogs remains uncertain. As Jindo is isolated from the mainland, Jindo dogs seem to have kept relatively pure blood. The Jindo dogs of Jindo are protected by both the law for the protection and raising of Jindo dogs, and the law for the preservation of natural heritage. To protect the breed, it has been designated as Natural Monument.
