Shep has a way of sideswiping Laurel, which knocks her flat. He does it in one of 2 situations: 1) He just gets in a playful mood and runs past her, but not quite so it knocks her over, or 2) When Dh comes home she runs to greet him, but Shep wants to get there first, so he knocks her over because she's the littlest and the only one level with his head. He never does it with anyone else, so I'm thinking he knows what he's doing.

For the second situation I'm going to leash him as soon as I hear Dh coming up the drive, then make him sit while he says hi to the kids. But what can I do about the other situation, which seems to happen out of nowhere?

We are due to start obedience training in about 3 weeks, but I'd rather not wait that long to ask the instructor. Just wondering if anyone has had this experience before and what you did about it
