BUT, I really need help with this!! He sleeps in the house...then I put him in the pen for a few hours. When I go to get them in the afternoon...as soon as I open the gate..he flies out and BITES me...yes, BITES me..........then runs around the pen a few times (it's his and Addie's game). Then he comes back into the house. Now Dave feels it's his way of 'playing' or something..........IT HURTS!!! And, I'm just sooooooooooo not happy with this at all. I've tried a few things....now, I'm trying to hide behind the gate. He only does this when first let out...OUCH!! I've tried yelling......I've even bopped him a good one on the nose (yes, I know this isn't recommended) I just don't know what to do. He doesn't do it in an aggressive manner.....but it still hurts darn it!!! This has been going on for the past week..........I'M SICK OF IT ALREADY!!!!!!!!!!!!! It's the only time he does it.......altho he still tries to bite at my legs when we are walking to the house...by this time I have him leashed and I pull up and say "no" and it stops. HELP!!! I REALLY HATE this!!!!
