^^^and Im glad it worked for your mare

, however, and I could be wrong but I took it from the tone of the post that the OP said her horse was well broke but has just lost his topline from no work.
Its a totally different situation as she doesnt say he runs through the bit and he certainly wasnt a buggy horse so its for sure he has no problems from that.
She should be able to simply ride the horse back to fitness, and that just takes time.
