It sounds as though the saddle is not level, but rather is sloping down into the mid-section of your horse’s back. She could be dropping her back to avoid discomfort, or the saddle could be propped up and too tight at the wither. To determine the problem, put your saddle on with no padding underneath and do not cinch up. Try to run your hand in between your horse and the saddle from the front. Your hand should be in a palm up position with the back of your hand against your horse; your palm feeling along the bottom of your saddle. If your hand slides in easily, then you have enough room at the wither and the Cavallo Total Comfort System Wedge Pad with all its benefits and features would be a very good solution to your balance problem. Whilst all Cavallo pads create more room at the wither, they cannot make your saddle wider. If your hand really has difficultly sliding in, your saddle is too tight at the wither and you should consider a new saddle.
