Not sure if this is the right place for this post but any thoughts appreciated!
My 16-year-old TB has a training hole that I’ve never taken the time to fix in my seven years of owning him: if he steps on his lead rope or otherwise feels that his head is ‘trapped’, he will pull back in a panic until the offending object either breaks (RIP a couple of halters) or slips free. I know many folks have trained this reaction out of their horse by methodically teaching them to simply stand still and wait to be rescued in situations like this. I would love to do this with my guy but am not sure where to start. He otherwise has excellent ground manners, yields to pressure easily, etc. I would love to be able to ground tie or otherwise allow unsupervised grazing etc without risking a snort-pull back-break things incident (and of course imagine this skill would be very useful in an emergency where, god forbid, he gets truly stuck in something. He is exceptionally accident-prone so this is not out of the realm of possibility.)
Does anyone have any resources they might point me to in order to work on this, or would like to share a method that works for them? Many thanks in advance!
