2. If you didn't lace him a good one on that kicking leg with the riding crop or buggy whip, you should have.
I don't care what he is or isn't lacking in his herd bound brain, that kind of behavior needs to be stopped.
I don't blame the trimmer one bit for not wanting to work on him again. It's not her place to discipline him.
I know where I speak from because I have one horse out of four that has gotten more lacings in the 16 years I've owned him than my entire lifetime of Keeper horses put together. If I let one "well I DIDN'T hit you" kick go, the next time he will connect.
He is oat/corn/soy intolerant, and taking him off those things helped his attitude immensely.
But he has all indicators of becoming insulin resistant so I started him on Animed's "Remission". Was I ever suprised at the difference in his behavior.
He is #3 in the herd. He is so quiet these days, even the 27 yr old #2 horse has been allowing him to do the Itchy Thing. That has never happened in 16 years.
If you can't get Animed's "Remission", look into a solid magnesium product in Canada ---- and start disciplining him if you haven't already
I apologize for sounding ugly but the four things in this life my horses would think death looks good, is to get "it" for biting and kicking first and foremost. Bucking & rearing once I eliminate physical reasons or abuse if the horse is new.
