Description: The Thai Ridgeback is found mainly in Thailand. They are very intelligent dogs, which tend to have a mind of their own. Thai Ridgebacks are independent, somewhat undomesticated, and naturally protective of their own. The Thai Ridgeback is very intelligent and tough. Unfortunate to some, they can often be aggressive with other dogs and with strange people. The Thai Ridgeback is a medium sized dog, it has a wedged-shaped head, pricked ears with a short coat. It’s one of the oldest dog breeds in the world. Thai Ridgebacks have an interesting look to them, looking almost like they have been pushed back into their own skin, making it wrinkly around the neck and face. The Thai Ridgeback can be a variety of colors, being chestnut, red, blue, fawn or black. Some have been white as well, but it is rare. Thought to be the perfect mix of a spitz-type dog and a primitive breed, the Thai Ridgeback is a classic example of the results of isolated breeds. They are only one of three breeds every discovered to have a ridge of hair growing in the opposite direction on the back: the Rhodesian Ridgeback of Africa, and the Phu Quoc Dog of Vietnam. Thai Ridgebacks have up to eight different types of ridges along their backs, and some Ridgebacks are actually born without ridges or with plush coats! With a spotted or completely blue or black tongue, the Thai Ridgeback is truly a unique breed.

History: Thai Ridgebacks got their name by a ridge growing in the opposite direction to the rest of their coat. They have also been known in Thailand for at least 350 years. They were used by farmers for hunting and as a guard dog, and were once called the "cart-following dog". They are most common in Eastern Thailand, and have rarely seen outside of Thailand. They were kept pure by isolation, and are thought to be related to the Rhodesian Ridgeback of Africa and Phu Quoc Dog of Vietnam. DNA research is being done to determine this. Only until recently did American dog enthusiast Jack Sterling stumble upon the breed in Bangkok and exported a few to to America, more specifically California. Today they are still extremely rare outside of Thailand, and have been placed on the Foundation Stock Service list since 1997. The Dog Association of Thailand is now trying to ensure that the breed will continue to thrive in years to come. They are slowly becoming more common in the United States.
