I once knew a Southern woman of a certain age who, when taking her dog for a walk, would say, “I’m taking Clyde out to read his newspaper”, one of her many colorful turns of phrase. I was reminded of her remark as I walked my own dog after last week's heavy snows. Lilly, my Black Lab/Chow/mystery dog, makes the rounds twice a day, reading her newspaper in the smells left by other dogs all along the snowbanks that flank our sidewalks. The white piles of snow are marked every several feet with the yellow journalism of our obviously very dense canine community. But Lilly adds her own opinion to the conversation, writing over what was written earlier. It is a palimpsest in doggy dialogue. It is Facebook for dogs.
