Hi! My yorkie has a built in alarm clock and it's 5am...how do I get him to stop barking? He sleeps in the kitchen (in his bed) and I am in my bedroom, of course. He doesn't stop until someone comes in. I know he just wants to see someone. He gets so excited when someone walks in to greet him. I won't be able to travel with him unless I can get him to stop barking at 5am. Can anyone help?
