GF, I'm laughing at your pics of them playing hard. This morning Nikki was pounding on Lupa behind the love seat. Then Nikki came out and I could hear Lupa crying a bit. I went to look and see if he had hurt her back there, and she was laying on her side stuck under the sofa!
I guess from the position she was in she couldn't pull herself back out and was just laying there crying pathetically. I had to lift if up so she could get out. Poor thing. Our pups are rough on each other aren't they my friend.
