Notes
An ancient hunting dog of Thailand, the Thai Ridgeback dog is the only modern breed besides the Rhodesian Ridgeback that has a ridge of hair growing in the wrong direction on its back. It may sometimes have a blue tongue, suggesting east-Asian heritage. The breed gained attention on the island Dao Phu Quoc 360 years ago, but was mentioned as early as 400 years before that. Some claim it orginates from the African ridged Khoidog, which is the breed the Rhodesian Ridgeback comes from.
The Thai Ridgeback should appear slightly rectangular with a ridge on the back, muscular and agile. The head should have a long and powerful muzzle with marked stop and flat skull. The ears are set rather wise apart, large and triangular, carried slightly forward. The neck is strong and muscular, carrying the head high. Strong back with deep chest and tuck up. The tail should be carried high. The coat is short and soft with a typical ridge of hair growing in the wrong direction on the back.
