My OTTB cribs "lightly" if there is such a thing. He tends to do it more while eating. Out in a paddock he tends not to do it at all, and if there is grass he doesnt even think of cribbing. But after our recent colic scare, my trainer said we need to try a collar since he may have gastric issues. We got the miracle collar and put him on "neigh-lox" and the difference in my horse is stunning after only 10 days. He has finally gained weight easily, he finishes ALL his hay for the first time, and his gurgling stomach is quiet. His manure is better formed and more regular. All good.
However, I feel SO bad that he is wearing this tight collar!

He seems to move, eat, etc normally, it just looks mean to me.
Should I just get over it and consider it the lesser of two evils?
