Hello, down my local stables theres a pony which I am very fond of, but he frustrates me very much. He tries to bite me, but not in a wanting to hurt me way, he's like a child though he's 7. When I go behind his eye he throws his head around and moves away from me like forward. I want to know any insights in to how I can get him to trust me, but heres my problem, I can't do join up because he's not mine, so I wondered if anyone knows any trust building exercises that can be done when he's just in an area where all the horses stand? And how do I get him to stop biting me?
