Well' I have a Yorkie, I need not say more to those that have one. He has to have his way always. When someone's come's that he doe's not know he will bark every second until they leave. I guess he is protecting me and that is a nice thing to do. He rules, I just live here. I sure hope Dog Wisper is not reading this. He is so cute and love's me so much. Dog's don't love I know but I don't believe it. Well I was on a site and read about a product called Good Dog The natural way to care for your dog. I said sure! I added it to his drinking water and within a few day's he was so much calmer. It is for unruly or ryper dog. Mine is the hyper one. It works. What they say is true and we all lived happy the rest of our life. The END.
