I have a 16 month old golden retreiver. He is a very good boy, but for one thing. He will not come in from the backyard until he's ready. I know I can get him to come in with a treat, which I try not to do unless I'm leaving and have to get him in the house. I guess the thing that really bugs me is that he will come running if my husband calls him. Actually I think it's any male voice which I don't have, so what do I do?
