Some months ago, as the snow melted off the lawn, a rabbit appeared at the end of our back yard. Our twin shih tzus, Buddy and Bruiser, spotted the intruder and, barking furiously, headed off in pursuit. The bunny, having given our fearless duo a head start, then bounced off into the undergrowth, cotton-tail waving in the air, leaving them barking at each other as if to say “Where’d he go? Where’d he go?”
