Is there a real Dr. Bill?

YES! He is one of America’s most famous animal nutrition researchers. Dr. Bill developed products for many of the top brands of dog food but ultimately grew frustrated by their insistence on profit over quality. Dr. Bill is passionate about maximizing the health and longevity of dogs so he started his own line of dog supplements prioritizing proven research and searching for the best ingredients in the world.
