My wife Dawn and I took our dog Ginny to classes. We took her to playgroups. We gave her love and affection and discipline and water, plenty of water, because a dog was supposed to have fresh water at all times. And for all our efforts, our German shepherd was behaving worse every day, her latest victim the UPS guy, who now dropped off his packages at the foot of the driveway after the last encounter, which had involved teeth, pants, and unwanted ripping of fabric. Let’s just say it was a good thing he was wearing brown.
