Famed wildlife photographer Art Wolfe has chosen 100 of his favorite photographs of dogs from every continent of the world, joining bestselling animal writer Jeffrey Moussaieff Masson to create a remarkable book for a wide audience of dog lovers. In Tibet, New York City, Mongolia, Paris, Peru, Ghana--in fact everywhere, we see dogs living with humans in a kind of intimacy we do not find with any other animal. It is impossible to view these astonishing photos without agreeing with Masson and Wolfe that there is no other relationship in nature quite like that between dogs and humans. As Masson points out in his Introduction, dogs don't care about our status, our color, our money, our social class; the biases, prejudices, and presuppositions of humans are foreign to dogs. For 15,000 years, Masson writes, humans have encouraged them to become part of our lives, because we like being around them. And they too like being around us. It is a universal relationship that cuts across all cultures and continents. The mystery of it still defies explanation, but these extraordinary photos reveal that its uniqueness is understood throughout the world.
