Answer time: what do you see and how does this relate to saddle fit?
In this case, the horse has a stress line along the flank. While this can result from many causes in both ridden and non-ridden horses, this particular horse had a saddle that put pressure on the withers and spinal column. Constant, uncomfortable pressure causes the muscles to contract repeatedly, producing a defined line through the muscling in the horse’s flank. This is similar to when the horse repeatedly twitches away flies as a reflex, which is part of why you might see a stress line in a non-ridden horse. If you see a stress line in a horse that is ridden, be sure to investigate your saddle fit and determine if that could be the root of the problem. Your horse’s health, welfare, comfort and performance all depend on proper fit!
