But what are you teaching it by smacking (kneeing - whatever) if they don't STAND STILL. I am not talking about pawing or jerking, kicking etc. I am saying STANDING still. They don't stand - you knee them. They respond to pressure and move - correct?????
There is a difference between a jab and pressure, as in what you do on a lead line or a leg given as a cure for a turn. A jab in the barrel is quick, immediate, and an eye opener. What it isn't is pressure - you are not holding your knee there, which would be pressure.
A quick yank on a lead line is much different from steady pressure and sends a different message to your horse.
As for feeding your horse for bad behavior ... if it works for you then that is OK but personally, I would never - ever recommend it to anyone. It is giving a horse a reward for unwanted behavior.
