My 6 month old is doing the same thing upon occasion because he enjoys being outside and loves his softball. I've started leaving him outside (I could get him in with a cookie or if I really want him I just walk up to him and grab him). I go in .. he comes to the glass door and peers in, ball in his mouth. I go to the door and ask "Are you ready to come in yet?" He will turn and head to the stairs, stop and turn his head and look at me. I go back in and putter a little more (30-60 seconds or so). I go back and ask again. At some point, I'll hear a THUD which means he dropped his softball (he's not allowed to bring it inside). I go to the door and ask, "Are you ready to come in now?" He comes in. Note: I'm doing this because I don't mind if he stays outside for a few minutes although I constantly watch him from the door. I just didn't want to stay outside with him. If I need him to come back in immediately, I just don't take him off leash (I still take him to potty leashed, even in our fenced yard) and we head straight back in. Otherwise, I let him putter a little with his softball or his femur bone for a few minutes. Saturday, he stayed out a long time. I sat on the deck and read and let him putz around.
