It's a dog's life!Every dog has a tail to wag . . . and a tale to tell. Patricia MacLachlan and Emily MacLachlan Charest asked a collection of canines to speak up--and so they do, in words, barks, and yips. Captured here are accounts of happy days filled with squeaky toys, good smells, plenty of naps, and the very important jobs they do for the people they love to love.
