My pony sheds like a beast! She lightly started mid-January and went into full force shed-mode probably a week or two ago. She grows a buttload of hair too, and doesn't finish completely until July. We do suspect she has the beginnings of cushings. However, this year since she doesn't shed out (well, sheds out patchy all over), I will be getting her body clipped in ~2 weeks. In other years though I have found bathing works, really helps to loosen the hair. Otherwise, I haven't found much to help her.
