Horse Poor, really liked your post. I had to do the same thing with my QHx when he was a two year old. He was always fine with his feet then one day out of the blue he wouldn't let me handle his back feet. He never actually tried to kick me, he would shuffle the foot I was trying to handle, backwards and forwards. So while it wasn't a kick as such, it was still bloody painful if he caught me with his wildly waving foot. I did exactly what you described, I only had to do it the once and only with one leg. I honestly believe though that if I had not gotten on to it as quickly as I had he would have turned into a real ******* of a kicker, it was his nature to push as much as possible.
Cowgirlfitzy, sometimes all the ground work in the world won't solve certain issues.
