Jackie, My gelding foundered 2 years ago. After he was to the point where he was off bute and I could start exercising him again we found that he was short strided-didn't want to push from behind. My vet figured it was because he had been putting so much weight on his hind end. I had an equine massage therapist give him a good going over and she found all his rear end muscles very tight. Within 24 hours he was trotting like his old self. He now gets a massage every month. If there is someone in your area who is certified, it would be worth a try. Just be careful of people who say they took a 1 week course and know all they need to know. The gal I use went to school for almost 2 years-studying human massage first- which actually gives her a better insight with the horses. Barbara
