A cribbing horse will always be a cribber. There are some claims of "cures" but in all the years I've been around horses, I've never seen one that was permanent.
I've had horses that learned to crib with a collar on.
This is a mare that I bought several years ago. There is no collar on her but you can see how she learned how to crib with one. BTW, I undid the deal when I found out she cribbed. Windsucking mare (cribbing) - YouTube
