So I got my horse a year age now and ive been trying since then to get her to ride with a snaffle. My last ride didnt go so well, got on and went right on my face, got back on and she tried to roll on me. I cant seem to figure this horse out, thats makes the horse 4 and me um 0 lol. when i first got her she rode with a hackamore then she got to where she wouldent respond to it anymore, so i sought out advice and was told to go to the snaffle with no luck. Any ideas?
