I wish I had a photo of Darby and Bonnie play fighting. It sounds HORRIBLE, involves the showing of major teeth, and lots of rolling, tumbling and bumping into furniture.
When it takes place outside, it involves Darby breaking away and running like a mad man around the backyard, swooping in now and then just close enough for Bonnie to lunge at her.
Bonnie makes ALL the noise, until she gets tired and stops playing. Then Darby starts barking at her, asking her to play again.
It's fun to watch!
But, Glenn doesn't appreciate it when they decide to do it in the bedroom while he is still asleep!
