Origin and history
Where the breed comes from
The Phu Quoc Ridgeback is an ancient and primitive breed native to Phu Quoc Island in Vietnam's Kien Giang Province. For centuries, it was used by local people as a loyal companion for hunting, guarding property, and carting. The breed's exact origins are not documented in detail, but it is considered one of the oldest indigenous breeds of Vietnam. Its distinctive back ridge is a natural trait that has been preserved through generations. The breed's history is closely tied to the island's rural communities, where it served as a versatile working dog. Today, the Phu Quoc Ridgeback remains relatively rare outside its homeland, and its recognition status varies by registry, with no major international kennel club yet granting full recognition.
