I adopted a horse, when I adopted him they told me that he could be tied, but not cross tied. So I put a tie post up walked him over to it, tied him up, he reared broke the brass ring and off he ran, he walked right back to me. Grabbed another lead line and tied him back up, well after 4 broken lead lines I am at a loss. He is a 10 yr. Old 16.2 hand Thourobred, he is very sweet but once you tie him he becomes crazy. Any Advise of how I can aproach him to make him realize tying him will not hurt him.
