To clarify...I don't walk him on a long lead. The time he was able to kick me was because he pulled the rope through my hands when I tried to yank him away from the grass, leaving me holding onto the end of the rope.
You have no control over this horse. He is doing whatever he wants to, and the only time he is doing something you want?
Is because it suits him at that moment.
If you do any of the following. Quit it.
Baby horse, use soothing voice, pet him, praise him, feed treats, ignore things he does, allow him to have pinned ears and nasty attitude, let him be feed dominant.
Any and all of those? Will lead to a horse reading you as submissive. More so if horse is a dominant horse to begin with.
This is how you should be leading horse.
Have lead coiled in left hand, with right hand on lead so that your forefinger is resting along lead and it is pointing to horse.
PAY ATTENTION to the horse, you are missing the cues horse is giving you as to what it is going to do. Raising head, getting belligerent eyes, and quickening steps may be signs you will get. And one ear towards you and other away? Means horse is thinking and that is not a good thing.
Keep horse's throatlatch at your shoulder, so that you can have idea of what horse is up to. Not ahead, and not behind. In this position, you can quickly and firmly correct horse. Keep your eyes open for tempting patch of grass too. Be ready.
If you "feel" in your mind, and you should be able to, the horse drifting off in its mind, take your forefinger nail and lightly and I mean LIGHTLY jab it into side of horse's face, or can turn hand with lead so can use thumbnail instead. I use both. At same time, tell horse "Stop it" and walk on. Do NOT look at horse, just keep gaze ahead of you. And in a bored voice too, no excitement here. Keep walking.
This whole thing is BORING you to tears, and you don't' have the energy for this...just say Stop it. Walk on.
If horse persists? Let horse pull away very slightly, maybe one inch at most and then bring horse back to you at same time you make a knuckle with forefinger and POP horse with it, NOT moving your hand or body, you have brought horse back into your knuckle.
NO indication that you have done anything. Nothing. Just walk forwards.
At your decision, and only yours, then this.....
Stop completely. Dead stop. If horse wants to forge ahead, stick elbow out and, elbow with elbow bent, so elbow point in shoulder as you are still facing forwards. Quick and sharp too.
Never turn to horse to correct him, as you want to be in the attitude superiority position here. Facing horse like this, means you are giving him a chance to negotiate to him and he will be more prone to argue then.
Act as if this is the most boring thing you have ever done.
And at this point? You are NOT his friend, you are HIS BOSS...and he is beneath your notice, so keep that mindset, and breathe it, walk it and think it. Get your shoulders back and OWN that horse.
If you have little brother? Use the attitude that he has stolen something from you and you are going bear hunting with a switch.
Stand there...count to 23 or more....slowly. THEN you decide when to walk. Repeat this.
Any corrections you make have to be sharp, concise and to the point. Shillyshallying around with horse like this will do no good and will get you hurt.
Remember NO BABYING, NO TREATS, NO PRAISE...horse does not deserve any of it and it will make a nice horse into a monster, and a horse that is already a monster? Into a danger to be around.
