We have a 11 yr old OTT TB that we've been working with for the past 6 months to convert to a hunter. He's a dream to ride and is jumping around courses like a he's done it forever. Occassionally he over jumps if the jump is new, especially now that we're starting to raise and widen the jumps to maybe 2'6-2'9. Now he's experiencing soreness behind the withers, but not on the back where the saddle sits, and not where they would usually get back sore from jumping. It's in a place that my trainer normally doesn't see soreness due to a saddle. We both ride in devoucoux saddles, and they both seem like they fit him fine. Anyone ever have their horses sore in this spot? We're wondering if he did something stupid rolling out in the field.
Have you thought about massage or a chiropractic work-up?
Speakinh from experience your saddle might not fit as well as you think it does. Or maybe his back has changed as you have worked with him?
I have had great experience with my local massage therapist. He also happens to be a saddle fitter. Your fix might be as simple as a half pad with some shims. I would maybe have a fitter look at your saddle or have someone come work on him
