Yesterday my first horse arrived at my house. "Spike" is a 9 year old gelding who supposedly rides(for pony rides) and drives. And let me just say-- I don't believe that crap for a minute! I lead with a loose lead-line and very little pressure when just leading him in a straight line moving forward, and he is bumping into me, nudging me with his shoulder, stepping on my feet(OUCH!), and/or moving ahead of me/falling behind me. When I stop, he kind of circles in front of me and stands with his body sideways and usually his neck ends up right in front of me. So I just continue walking in my straight line, right through him. I tried to establish space by wiggling the lead-line, telling him back, and applying pressure to his chest to back him, but he still looks terrified as he backs up. He disengages his rear nicely when I spin him around, but then seems to overcompensate when I stop asking him to move. He is easy to catch, as he just stands still, but has not so great ground manners. I know that this is NOT going to happen overnight--but I am just making sure that there isn't something that I should be doing that I am not. How can I help him to trust and respect me as a leader?
