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!
