Just some thoughts on some comments I think worth further consideration...
do a "neck twitch" to keep him still. He won't move while you are pinching him and he will get the point.
IME 'twitches' of any kind are in no way reliable. If you pinch a horse while they're standing still, what point exactly do you think they're getting? I personally don't want a horse to 'get the point' that standing still is something it gets punished for.
I do have to kind of laugh though at the notion that once taught "properly"- the horse can be expected to never do anything bad ever...
... And for those of you who think you NEVER hit a horse for any reason...
Must have missed those bits, don't recall anyone saying anything of the sort. But yes, if they were said, I personally disagree with them too.
Oh! AMEN! To this! The best trained horse can and will misbehave on occassion. .... knowing he was the trainer for a stallion, I didn't even hesitate walking into the pasture with him and catching him
So what are we saying here?
As my trainer says....you have 5 seconds to "kill" them. After that, you're too late and just being mean.
Actually, this is a misinterpretation(& I don't get where the 5 seconds came from). Animals learn by *instant* association and don't get abstract ideas such as 'What I did earlier earned punishment now'. Different animals have different capacities for association. What is often touted as 'the 3 second rule' comes from studies they've done with dogs that show that *at worst*(meaning you should never plan to be so tardy about it), dogs can often still associate cause & effect if the punishment happens within 3 seconds of the 'misdemeanor'. Similar studies on horses show that they have much less ability in this way & they don't link cause & effect if it's any later than a second or 2 after the behaviour. So... it's important to punish/reinforce any behaviour you want to effect *at the time of that behaviour*, but at worst, you might be in luck that the horse actually works out what the consequence was for if it happens within 2 seconds max.
I'm not at all against punishment personally, used correctly & judiciously, but the idea that it's OK to make them believe you're going to kill them(regardless of timing) has absolutely no basis in anything so far as I know & is not something I'd advise you do to a prey animal you want to trust & respect you enough to 'behave' safely for you.
