Not much you can do. If they are making a lot of ruckus close by, then you've been busted somehow. Or they've heard it all before and are giving warning barks. Without hearing the sounds they made it's tough to say what happened. All you can do is sit tight, and try to coax them with different sounds. Typically dogs that really want to come in do, and they do it right now without making a bunch of noise. In fact they rarely ever make a peep before coming in. Sometimes, but it's not the rule in my experience.
