Russell’s dog Betty is here for a visit. At our house, her job is to protect our backyard from squirrel invasions. She sits atop the back steps, ever-vigilant, ceaselessly scanning for squirrel intrusions and the foul depredations that would inevitably follow if one of the furry rodents were to actually set foot in our yard.
At some point in the past, Betty’s ancestors must have had a serious run-in with squirrels. Betty carries around the genetic memory of that encounter in every fiber of her being. As a result, no house in the neighborhood is better protected from squirrel trespass than ours. The squirrels steer clear when our Squirrel Sentinel is at her post.
