I would also really recommend Canine Shine.  I started giving it to my dogs after having such a good experience with the Horseshine.  People (my vet included) always comment about how shiny and healthy they look.  I gave a bag to a friend who’s dog was itchy and had a dull coat.  After one bag he looks like a different dog, all silky and shiny and no more itching.  Keep up the good work with your products!
