The Thai ridgeback is a breed of domestic dog of the pariah-type that originated in Thailand. The exact origins of this breed are unknown because it is an ancient breed, but it is thought to have been developed in eastern areas of Thailand. Genetic studies have shown that this breed, along with the Phu Quoc ridgeback, is most likely descended from the ancient Funan ridgeback dog.
The Thai ridgeback is a medium sized dog that has a muscular build, with triangular ears and a slightly curled, erect tail. It differs in size depending upon the sex, with males reaching an average height between 22 and 24 inches and females reaching a height between 20 and 22 inches. The coat is short and coarse and is typically red, black, blue, or tan in color, and black masks are acceptable on red individuals. The standard does not accept white dogs or those with brindled patterns. The ridge of fur that defines this breed grows in reverse from the rest of the fur and extends along the back from the hips to the withers. This ridge fur can grow in nine patterns including an arrow pattern, a saddleback pattern, and a leaf pattern, but the standard requires that any pattern be well defined.
The Thai ridgeback does not have any major health issues, although some purebred individuals can have dermoid sinus and modern individuals may be prone to hip dysplasia. This breed is intelligent and typically active and it is recommended that proper training and socialization occur at an early age, due to the natural guarding instincts that it displays. The Thai ridgeback is recognized by the AKC, FCI, and UKC.
