When you have a horse that kicks, you teach your horse it is not acceptable, and you learn to dissengage the hind end as horses go by on that side. It is really quite easy. I rode a horse for an owner who's horse kicked.
He had not learned this. I taught his horse, and then him. All you have to do is turn the horse's nose toward the side on which the horse is passing, apply pressure with your leg on that side, and bend the horse around your leg. It makes it virtually impossible for the horse to kick at that point. When you are consistent about this, the horse will expect it, and know you will not allow it.
I came in on the tail end of this post, but my mare kicks, a confirmed
kicker of all things great and small.
i put long large red flags all over her and verbally warned folks of her
kicking "all things great and small" people dogs horses....but at the
ride people rode up her tail and I still warned again about her, it
amazed me of their lackadaisical attitude.
Out of curiosity, how do you expect people to safely pass
