- BRIEF HISTORICAL SUMMARY
The Thai Ridgeback Dog is an old breed which can be seen in the archeological writings in Thailand which were written about 35O years ago. It was used mainly for hunting in the eastern part of Thailand. People also used it to escort their carts and as a watch dog. The reason why it has kept its own original type for so many years is due to poor transportation systems in the eastern part of Thailand; it had fewer chances to crossbreed with other breeds.

Reachy stride with no pitching nor rolling of the body. Parallel tracking at normal speed. When viewed from the front, the forelegs move up and down in straight lines so that the shoulder, elbow and pastern joints are approximately in line with each other. When viewed from the rear, the stifle and hip joints are approximately in line. Movement in a straight line forward without throwing the feet in or out; thus enabling the stride to be long and drive powerful. The overall appearance of the moving dog is one of smooth flowing and well balanced rhythm.
