I totally disagree. If I had been there with a whip that horse would have whip marks on him. GRRRRR
Please don't suggest that a human, who is 8x-10x smaller in size and weight should NOT defend himself or herself.
Too many people keep animals that are out of control. It isn't cute and it isn't funny. It is HIGHLY DANGEROUS! Better that the OP reacted immediately and the horse was hit in self defense that the human was injured and the owner sued. Think about it.
After the fact, you can't do much.
I would tt the barn owner about this. I would also tt the owner, when the horses aren't around about it, but I doubt that would change anything. UNfortunately, you're probably stuck with keeping a distance between the owner and you AND the owner's horse and your horse.
Horses don't normally strike at each other.
It is a VERY AGGRESSIVE behavior.
Biting and kicking while in the pasture is pretty normal.
I did not suggest the person not defend themselves. But, this already happened. She asked if she should have done something after the action that happened, such as say something or discipline the hrose herself, since the owner apparently will not.
While it would make me very angry to have someone else's horse strike at me and them do NOTHING, say NOTHING, if I took a whip and started into smacking on their horse, I would make any future interactions with them likely impossible. Yes, THEY should discipline their horse, or at the very least, apologize. but if you take matters into your own hands and decide you have the right to do this, then be prepared to have very bad interpersonal relations with someone , who you might share the barn with . Can make being at the barn really ugly.
It's possible the person is clueless and rather than you leaping on their horse with a whip, you might risk some advice, but my experience is that advice given when not asked for is rarely heeded or appreciated and usually comes back to bite you in the butt.
Better to pointedly avoid this person, IMO.
