I have tried many different feeds and additives over the years, but was unable to keep up on the condition on Shimmy. Andrew of Blue Ribbon recommended the Old Horse Mix, he advised me to use it as a full feed and not add anything to it. Within weeks of using Blue Ribbon, Shimmy has put on weight and his coat and energy levels improved drastically. Shimmy is 25 years old and his competition has been outstanding and he looks fantastic. Great advice and product
