I have a Double J Pro Racer Wide fit that I believe is too wide on my mare. I think the fit has gotten worse potentially because it is atrophying her shoulders even though the saddle seemed to fit decently when purchased. I need help in figuring out what steps to take next. Would a regular width fit her? Does anyone have a similar experience? I have attached some photos of her with said saddle on + some pictures of just her back for an idea.

yeah looks too wide. you could try a thicker pad maybe a csi? Also might just be the wrong tree for her back. it almost looks like its rocking on her. hard to tell exactly
