Jody has white hairs on her withers now, on the left side. I presume it was from that marathon trail ride over Labor day weekend. Five hours was just too much, for a horse hardly ridden. We used my Big Horn saddle, like your husband's on her. So, now it's solve that problem, of what is pinching her.
Yeah - good to solve it! Sometimes you don't know there's a problem till those marathon rides. It's all in degrees.
I just want to have my confidence in my system back. So many unknowns with Bay about whether his white hairs were from one ill-padded ride or are part of an ongoing fit issue that needs corrected. His original fitting was three years ago, backs change, pads wear out. So out of this he'll get a new pad(s) that are right now.
