I have a 12 year old mexican gelding I just saved from going to slaughter. He was reportedly used as a camp horse. He is well broke. I've only had him going on 3 weeks. Initially I was able to get close to him, brush him, and even put a blanket on him, (all in the first week) He still talks to me every time he gets feed and hay, and comes to the fence when I get close to it. In the past 2 weeks he seems to have regressed. I can get him to come to me if I have a treat or food. But just walking in to collect feed bowls, or if I just try to spend time with him, he won't let me close to him. Does he just need more time or is there something else I can be doing? What am I missing here? Thanks for any help.
