Fitted the saddles this morning, you guys where right! :)
I have semi-quarter horse bars, but he's grown the the point where he needs full Q bars. I'm selling my saddles now (both the western and english) and I'm going to get ones that fit. When I fitted them this morning (I read online about fit and watched some videos) I saw that the saddles put quite a bit of pressure on exactly the spot where it was turning white! I'm so glad I caught this when I did, and asked about it! I had no idea what it was from, but now it won't cause problems down the road and I've learned something to look out for in the future. :)
Guess I'll be riding bareback for a while! :p
Thank you all for your help!!
P.S. Anyone want some saddles? :~)
