History

There is considerable debate as to exactly when and how the breed arrived to the island of Phú Quốc. The breed was originally a

. Historically, Phu Quoc Ridgebacks were not purposefully bred, instead relying on random pairings in the relative isolation of island life to continue to maintain their unique population. According to native Phú Quốc islanders, there were originally three sizes of the breed, each uniquely bred to hunt different sizes of game over different terrains. Unfortunately, purebred examples became scarce after the introduction of non-native dogs to the island, with many French writers noting that the breed was near extinction by the turn of the 20th century. Despite the near extinction, genetic studies indicate that the Phu Quoc Ridgeback population is genetically diverse. It was commonly thought that the Phu Quoc Ridgeback derives from the Thai Ridgeback, but recent research suggests otherwise. According to a genetic analysis, the Phu Quoc Ridgeback is most closely related to Korea's

Description

Medium sized with a hound shape, but with a larger head and well-developed muscles, the Phu Quoc Ridgeback is genetically and morphologically different from the Thai Ridgeback. All or part of the Phu Quoc's tongue is blue in color and the feet are webbed. Phu Quoc Ridgebacks are prized for their ability to run fast, swim well, and follow either a hot or a cold trail. As hunting dogs, they are known for their versatility, working both individually and in packs to take down a variety of prey including mice, fish, deer, and water buffalo. They also make excellent camp dogs, alerting to intruders.

. The four Phu Quoc dogs (two males and two females) were raised by King Gia Long and accompanied him throughout his journeys. In the book "Nguyen Phuc royal genealogy and pedigree explanation," a hereditary book that records and explains everything related to the royal family, detailed information about these four dogs is described, not only their achievements but also their distinctive characteristics as Phu Quoc dogs.The book "Nguyen Phuc royal genealogy and pedigree explanation" is still preserved in the family of Mr. Nguyen Phuc Ung Vien, who is a descendant of King Minh Mạng. These Phu Quoc dogs saved King Gia Long from danger twice before his ascension to the throne. They helped him escape the pursuit of the Tây Sơn army and ensured his safety. After ascending the throne, King Gia Long, when bestowing titles and rewards to his generals, did not forget to confer an honorary title upon the four Phu Quoc dogs: "Cứu khổn phò nguy Tá quốc huân thần Thần khuyển đại tướng quân", which translates to "The Great General of Divine Dogs, who saved the nation and assisted the king during times of peril." When the four dogs died, the king had them buried and established a majestic temple to honor them.
