Not to distract from the original question, but what does everyone recommend for a horse who moves into your space when they are afraid? Say they are walking respectfully beside you, but then a plastic bag blows by. The horse is then petrified and wants to be right up against you as much as possible? My friend's mare does this, but only when she is afraid. It's like she is seeking comfort when she is scared. How would you correct this behaviour? I don't think you can treat it the same as em Jay's issue.
I do not beat the horse but get really frightening with my body language and voice.
