Never Crib is a product from Stock and Noble that is designed to prevent horses from cribbing or gnawing on wood fences, barns, and other structures. 
It is a specially formulated paint that contains a bitter taste that horses find unappealing, which discourages them from cribbing. 
When applied to timber surfaces, it has a repulsive taste that deters horses, birds (cockatoos) and dogs from chewing or cribbing.
