What Is the Jeju Dog?

The Jeju Dog belongs to the order Carnivora and the family Canidae.

It is an indigenous Korean breed that developed naturally on Jeju Island over hundreds of years, adapting to the island’s volcanic terrain and rugged climate. Traditionally, the breed served as a hunting dog, guard dog, and livestock companion.

As industrialization and the introduction of foreign dog breeds increased, the purebred Jeju Dog population declined dramatically. Today, restoration programs are working to preserve its bloodline and gradually increase its numbers.

Adult Jeju Dogs typically measure:

• Body Length: Approximately 70–100 cm (28–39 inches)
• Shoulder Height: Approximately 45–60 cm (18–24 inches)
• Weight: Approximately 15–25 kg (33–55 pounds)

Their average lifespan is 12–15 years.
