Thank you all for your thoughts. I do show Reining cow horse so the legs are totally imortant and he is definetly not cheap. I was just thinking I would save a few bucks and spare my trainers feelings because I have been around this horse since he hit the ground so I do feel pretty safe but you all are right and I will definetly have the exam. Wish me/us luck! I will let you know how it goes =)
FYI: We use the same vet. This is a very small town and there are only two options but he knows us both very well and I think he will give an honest opinion.
