Notice how your horse twitches when a fly lands on his back? See how that skin moves on his shoulder?
There's a thin leaf of muscle called the cutaneous trunci that allows that twitch. When this muscles is
constantly fired, however, as in a bad saddle pinching behind the withers, or a sensitive horse twitching
in apprehension of pain, a line will develop across the shoulder. See the photo for an example.

The video clip is a horse who was ridden for so long in such a bad saddle that you cannot even
approach his withers without him twitching in anxiety. He has saddle sores and scar tissue behind both
shoulder blades.

These horses can be rehabbed, but it takes a significant amount of patience, understanding, and time.
