The owner said that he has done this since she bought him 9 years ago. He is a very good horse but I do not want to run the risk of having problems later in life if I choose to buy.
I only was able to see the horse for about an hour. The owner seems to be reliable but she could be lying just to try to sell the horse. She says that they have done Xrays and the vet found nothing.
Any thoughts on what is wrong?
