Phu Quoc ridgeback dogs are a breed of dog from Phu Quoc Island in Vietnam’s southern Kien Giang Province. The Phu Quoc Ridgeback is one of only three breeds that has a ridge of hair that runs along its back in the opposite direction from the rest of the coat (the others are Rhodesian Ridgeback and Thai Ridgeback).
The Phu Quoc dog was included in the Larousse Dictionary and is today gaining notice in the Western world.
Breed History 
Native to Vietnam, the Phu Quoc Ridgeback's history has not been well documented. Enthusiasts and few experts believe that all Ridgeback breeds (including the Phu Quoc, Rhodesian, and Thai) originated in either Asia or Africa, due to their distinct ridge markings along the spine, though this has never been confirmed scientifically. It is also believed that, like the Thai Ridgeback, the Phu Quoc has been used as a carting, escort, hunting, and guard dog throughout its history due to its impressive appearance and muscular physique.
According to old people on Phu Quoc Island, the dog was traditionally four main colours: spotted, black, yellow, and striped; however now the colours have become more varied. A mature dog is about 20–25 kg, with a small head, long neck, quite a long snout, thin yet long ears and dark speckles on the tongue. The body of tapering belly, straight legs and webbed feet, this allows Phu Quoc dogs to swim and run exceedingly well.
An important sign to recognize a true Phu Quoc dog is the ridge on its back, together with short, thin hair. When facing competitors or running after prey, the hair on their back become erect, creating a ridge making the dog look brave and strong. Now, it is quite difficult to find purebred Phu Quoc dogs, as they have mixed with other breeds.
The Phu Quoc Ridgeback is best known for its ability to jump higher and run and swim faster than most other breeds. These dogs love to hunt and chase, and are also known for protecting their home. This breed is extremely loyal, loving, and naturally obedient, thriving on dependable human relationships. The Phu Quoc is an intelligent and curious breed that loves to learn.
Due to its need for strong human relationships and its obedient nature, the Phu Quoc Ridgeback typically responds well to basic training and commands. These dogs enjoy learning and pleasing their owners, and can be taught to perform most any task its trainer is willing to take the time to teach it. Establishing immediate dominance and trust are keys to training the Phu Quoc Ridgeback.
The Phu Quoc Ridgeback remains rather rare outside of its native Vietnam and can prove difficult to obtain. Individuals seeking to purchase this breed will often encounter such challenges as inability to locate a breeder, high prices, and long waiting lists. More and more visitors are beginning to come to Phu Quoc in search of the dogs, giving rise to four breeding camps on the island, which now raise about 600 dogs. Most are sold in HCM City, ranging from VND 800,000 (US$ 50) to VND 3 million (US$ 150)
Advantages And Disadvantages 
There are many benefits to owning a Phu Quoc Ridgeback, such as their no-hassle coat. This breed is highly intelligent and easily trainable and can be taught to perform most any task or trick. Proper socialization can greatly improve the disposition of the Phu Quoc Ridgeback. The Phu Quoc gets along well with children and other pets when properly socialized. These dogs thrive on dependable and lasting relationships with humans and are known to be affectionate, loving, and loyal. The Phu Quoc makes an excellent family pet and companion. While this breed is overly trusting to strangers, it does make a nice deterrent simply because of its impressive appearance.
There are also disadvantages to owning a Phu Quoc Ridgeback. These energetic dogs require large amounts of daily exercise and room to run and play. Anyone wishing to purchase this breed lacking the adequate amount of time and space to dedicate to the dog is strongly advised against doing so. A Phu Quoc Ridgeback not receiving the proper amount of exercise will often act out by destroying property, chewing, barking, whining, and ignoring basic training such as housebreaking. Due to their hunting instinct the Phu Quoc Ridgeback will occasionally indulge in a good chase. These dogs are fast and difficult to keep up with, and may pose a threat to other animals, neighborhood pets, and small woodland creatures. The Phu Quoc Ridgeback must be leashed or properly secured at all times when outdoors. The Phu Quoc relies heavily on strong relationships with humans and therefore suffers from separation anxiety. Individuals wishing to purchase this breed who travel regularly, have full-time work, or are daily away from the home are advised to research another breed. During an attack of separation anxiety the Phu Quoc Ridgeback will act out of nervous destruction and may destroy property, chew, whine, bark, and ignore housebreaking training.
Common Health Concerns 
While the Phu Quoc Ridgeback is generally known as a healthy and hearty breed, they do suffer from a few health problems, including: hip dysplasia, various joint problems such as arthritis, patellar luxation - dislocation of the knee, and bloat.
