They say if a dog and a human love each other enough, they'll start to look alike. And if there's one thing you can say about the owners at the Westminster Kennel Club show, which ended yesterday with the triumph of Hickory Wind the Scottish Deerhound, it's that they love their dogs very, very much. Whether the dogs love them back is harder to tell. We sent a reporter and photographer backstage for the past two days to investigate. What they found was a mess of licking, strange hairdos, and ennui.
