I have been riding my 4 yr old OTTB in my close contact jumping saddle. He has been off the track about 7-8 months now and I started looking for a dressage saddle, mainly because I think the shape/seat will assist in the issues I sometimes have with my legs (misaligned disc in lower back sometimes causing my leg(s) to go slightly numb). We are also mainly doing flat work right now (has been started over fences, but he goes over fences very rarely). I tried one saddle out but did not like it, so I found one on Ebay for cheap that I know I will like better, so hopefully it fits my boy (if not I will resell it). Today, somebody told me that using a dressage saddle on a young horse wasn't good because of their backs (needing enough muscle for a "full seat").
Does anybody agree/disagree with this statement? I was told before that it wasn't wise to ride greenies in a dressage saddle because if they act up you can't get up out of the saddle to handle the situation, but never because of their back. He is sane enough to ride in a dressage saddle, but I obviously don't want to hurt him in the process.
I, personally, don't think the saddle I bought has a terribly deep seat (Crosby Freestyle), but wanted to get other's opinions as to the statement I was told today.
