she did have a brand new saddle but I don't have her anymore due to her having laminitis and cushings
Thinline. It's amazing I use it on my pony and she has had a better attitude since
You should probably get a new saddle lol… If your horse has back issues because of poor saddle fit, that's really unfair to your horse. There should never be a large gap between the saddle. Saddle pads should never and will never completely fix saddle fit issues.
