The pony may just have flat withers. Doesn't mean the pony is fat, just that there aren't enough withers to hold the saddle in place while getting on. I honestly don't see what the problem with using a mounting block is, especially because having a saddle dragged across the back when trying to get on is -not- a good thing. As for the classes, not sure. Maybe just don't do those ones?
