I am having saddle fit problems with my 3rd level warmblood gelding. His build seems average, but with big-ish shoulders. The issue is that apparently both shoulders extend back pretty far into the saddle area, and the Right shoulder is bigger than the left. Whatever I put on him tends to get pushed over by the larger right shoulder and shift to the left. Many saddles tend to ride forward onto his shoulders, but even when I get one that looks like it has good shoulder clearance, is still shifts left. A shoulder-relief (anatomical) girth helps a bit, but doesn’t completely fix the issue. A fore-girth is of no use, it actually makes the problem worse by pushing the saddle back more on the right.
I have tried many saddles and have had other people ride in them too; so I am sure it is a horse/saddle problem and not me riding crooked. The horse is not markedly assymetric in his movement (he has a stiff side and a favorite lead like most horses, but not extreme). I do often feel that the crooked saddle and inability to shift my weight to the right affect my ability to get the bend and lateral work that I want.
I have now had one saddle custom made for him, and another saddle with an adjustable tree where we had the tree adjusted asymetrically. Both saddles are STILL shifting to the left. I have worked with a good saddle fitter and adjusted the flocking on both of these saddles and others. I STILL can't get a fit that I am happy with.
Has anyone had a similar problem?? Any recommendation for saddles that might work? Especially saddles with very good shoulder clearance?
