I had a friend at the barn who was a veterinarian who worked in research for Purina.  She recommended the Horseshine after doing extensive research on supplements.  My 3 year old Holsteiner was completely bleached out.  Within 6 weeks, his coat was dark, shiny and dappled!!  I now breed and show Doberman Pinschers.  Your product is fantastic!  I don’t have to use spray on shine products, because they are so SHINY naturally from the Canine Shine!  Love this product!
