My 28 year old gelding Champ. Does not like staying clean. The day before the show, I ride him, and bath him. I use cowboymagic shampoo. Then I put slinky hood, tail bag, and leg wraps on him. But, he kicks the wraps off. Champ then rolls. It gets them all grown and green on his legs and back. But his neck stays clean. What should I do?
