I’m in the process of selling my current saddle with the intent of having my horse fitted for a better fitting saddle if/when the apocalypse dies down some and fitters/reps can go back to work. But in the mean time, I figured I’d see if anyone has had this sort of oddball fit situation.
First and foremost, I do not have good pictures that show this horse’s conformation; I’ve looked through my phone, and I just don’t have them. The horse in question is a Paint, comprised of mostly Quarter Horse and Thoroughbred. Big, big bodied, can just about pass as a warmblood when he’s his absolute fittest. He has a good prominent wither but it drops off steeply rather than tying long and deep in to his back. And he has (I hesitate to say, hollow) swales behind his scapula. This is not a fitness issue. His topline is as good and developed as it’s ever been; he’s just conformationally weird below/behind his wither. Another way to describe it would be that his wither and right behind/below is on the narrow side, while his shoulders are broader; it’s been suggested that we may need to try a slightly wider tree to accommodate his shoulders.
The problem I’m having is that my saddle slides back throughout the ride, settling in to the swale behind his wither. I have to stop several times a ride and readjust my saddle as it is putting me out of balance and starting to impinge on his wither; a breast collar does not help as the saddle slides too much and the collar causes discomfort. A “bandaid” or sorts that a fitter suggested is a basic gel no slip pad (just the gel, no fleece) placed a little behind where you would normally place a no slip/half pad, so as to fill in the swales without shimming and throwing off the balance even more. This is obviously a temporary solution and I would like to buy something that fits better, though I can’t fully customize to him because I do ride several horses of various shapes.
Has anyone had a horse built like I’m describing? Suggestions as to what to tweak on a saddle in this situation?
