Since my own little fiasco of trying to ride aside for almost a year with a sidesaddle that was terribly off balance, I have been trying to train my eye to see such things... This is a photo that shows how low the cantle of my saddle was.. which made it almost impossible for me to post the trot!
..so I ask you... is this saddle slipping?
..and is this cantle too low as well?
My answer to both is yes.
