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, hes 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 cant do join up because hes not mine, so i wondered if anyone knows any trust building exercises that can be done when hes just in an area where all the horses stand? And how do i get him to stop biting me?
