I have tried everything to stop my horse from cribbing and windsucking. I spent a fortune on collars that gave him a headache or basically did not work. This was my last resort. From the very first application he stopped. I was amazed. Used it for a month now and I was worried he'd get used to it and return to cribbing, but no! A miracle. All I need now is to buy a huge vat of this to paint the turnout fences :).
