The Squirrel Conundrum

I took my sister Susan's dog Blackberry for a walk up in Fort Collins the other day, and we  happened upon a squirrel, which immediately fled up a tree and absolutely captivated Blackberry's attention.  The squirrel jumped back and forth between trees, and Blackberry ran from one tree to another, tracking it's every move. And what would Blackberry do if she actually caught the damn thing?  If history is any guide, she would pretend she didn't see it, and then run off in the opposite direction.  Not a brave dog, but a sweet one.
