The withers are located between which thoracic vertebrae?

• A. T1-T6
• B. T5-T10
• C. T3-T8
• D. T9-T12

Answer: (C)

The withers sit at the highest point of the horse’s back, over the mid-thoracic region where the spine forms a crest just behind the shoulder. The dorsal spinous processes that create this crest are typically from thoracic vertebrae 3 through 8. So the withers align roughly between T3 and T8. The neck area sits cranial to T3 (near T1–T2), and the thoracolumbar transition starts around T9–T12, making T3–T8 the best descriptor for the withers. Breed or individual variation can occur, but this is the standard range used in anatomy.
