I own a cribber. He is an OTTB and has ulcers. I purchased him a little over a month and half ago, so I am still learning his personality and working him through this habit. He cribbed when you gave him a treat, rode him, and he cribbed after each meal. We started treating his ulcers but the habit didn't go away, so I'm thinking its a permanent thing. Although, I've added TractGard to his SmartPak and we are waiting to see if it works. He currently wears the Miracle Collar and it has helped! He no longer hangs around the barn so he has quick access to crib. He goes all the way out with herd and spends all day grazing.
