Sorry I disappeared. My 86 year old step-dad is almost 'gone' and I went to Colorado to visit him and my half-sister. I was gone 10 days and came back to more snow in Southern Oklahoma that in the Colorado mountains.
Okay -- back to a plan of action. I start out every horse by 'pushing them around'. I do not knock to slap them around but I darn sure push them around. As I said before, I particularly like to push a horse's shoulder / front end over and away from me. I know a lot of people like to make a horse move its hind end (called 'disengaging the hind quarters'.) I am not such a fan of that. It is too easy and not meaningful enough. It is too easy in that while it is quite a simple matter for a person to move a horse's hind end over, the horse can also do this to disrespect a person. If you want a horse to stand still and NOT move away like for grooming and saddleing, it is very easy for one to just step its hind end away just like you taught it to. So, I opt for the more difficult move (and one a horse cannot use against a handler quite as easily). I prefer to make a horse step its shoulder over 3 or 4 steps. I will switch sides and do it just as much or even more from the horse's off side. I find that getting a horse very 'light' and willing to move its shoulders from the ground makes it easier to get the same moves and respect from its back.
Then, I back a horse up from the ground -- a lot. It is a very submissive move to be deliberately backed up on the ground. I now only have two stallions. I have had as many as 10. No matter how well-mannered a stallion is (one of the ones I have now I have shown quite a bit) I ALWAYS back a stallion up several steps EVERY time I put a halter on one. As stallions tend to be very dominant individuals, I like to remind them every time I handle them that I am 'in charge'.
Once a horse has gotten spoiled enough to kick, bite or paw a handler, they may need more convincing that you are the boss of your herd of two. They may need a hard jerk or two on a lead-rope or -- heaven forbid -- a spanking or two. I, personally, am not a big fan of chain lead-shanks. I think they get more beginners in trouble than if they left them alone and I don't really need one. So, I just use a stiff 'cowboy style' rope halter. I know they look pretty 'tacky' in an 'English' barn, but I like them better than a chain. Just personal preference, I suppose. If a horse 'bows up' at me or just refuses to back up or move over (not at all unusual with a really dominant, spoiled horse), I will spank the horse on the chest or shoulder with a dressage whip or a twisted, folded up piece of baling wire. When I was training full time for the public, I kept a piece of folded up and twisted baling wire in my back pocket. It might stay there (like the hoof pick that is always in my other back pocket) for weeks at a time without ever needing it, but if a horse bulled up and refused to move-- or worse yet, swung its butt or tried to push its shoulder into me -- it was right handy where I could remind him who moved their feet first and where they were going to move them. Now, that I do not handle other people's spoiled horses very often and only handle my own (that have never had a chance to misbehave), I do not need to be as prepared. Like I said before, it is much easier to start them right in their relationship with you and never let them even think for a minute that they might be the dominant one in your pair than to fix a broken relationship with them.
Everyone should really take this to heart: Never peck or tap on a misbehaving horse. Spank it good and spank it more than is needed to just barely get the job done. You want it to NOT repeat the behavior and NOT try you again. If you are only going to just 'peck' on a horse, you are better not touching it at all. It only makes one madder and only makes one worse. Thrash it out good enough that it knows better than to try kicking or biting or whatever again and then you only have to do it once. Then and only then is it effective to spank a horse. If you spank one and it lays its ears back and it makes it mad, you did not do it harshly enough to make it effective and you only made the situation worse. This is how ALL of the really mean, vicious horses I have encountered got that way. Someone 'pecked' on them only hard enough to make them meaner.
Now, before all of you 'horsie huggers' think I am a mean old lady that is abusing horses and NOT using 'Natural Horsemanship', I maintain that I AM USING Natural Horsemanship and YOU ARE NOT! I am teaching a horse a lesson it will remember and respect just like the lead horse in a herd teaches it -- with great discomfort and misery -- I hope! Then, that lesson will not have to be repeated. If you have to repeatedly discipline a horse, then you are not doing it effectively enough to be doing it right. Done correctly --- It only takes once or twice at the most.
