Looks like Brooke and Wrigley have more and more in common. Besides their intelligence (and love of transporting things in their mouths), they also are both very food motivated. In addition, they each seem to be obsessed with the same thing ... balls! Both of them cant stay away from them, and when a ball is in the picture both the dog and the baby are glued to it. Sometimes I worry I'm going to need to get in the middle of a battle over one :)
I had typed and saved this before posting, and figures ... before I got to finish the post I had the altercation I imagined. Wrigley growled/snapped at Brooke over a tennis ball. She (Wrigley) is now on a time-out :(
