Hi guys, i have a Spanish & Appaolssa. i have frustrating saddle problems with my Appalossa. He is 14.2 and a barrel. had 2 saddles which sipped sideways so i invested in a made to measure. It slips in walk let alone a faster pace. I have had myself checked and my horse. I have a cotton numbh and dressage elastic girth, tried a sticky pad too. I thought the spanish where hard to fir sadlle to but the is driving me nuts and not doing my confidence any good either. Any ideas ?
