You stated he had less turnout in the previous barn,,where he supposedly was miserable outside, no matter what. But that's not the point. Horses grow their full coat only when all out without blanket.
Anyway, I think you want a quick fix, a band aid, because him cribbing " annoys the CRAP out of you", so, again, try the real sheepskin to cover the straps of the cribbing collar.
He was just started being blanketed last year, my stories about him shivering are from two years ago.
I don't want a quick fix, he has been cribbing for three years, why would I just now be wanting a quick fix?
