Jeffrey Moussaieff Masson has long been interested in the relationship between humans and animals, and he's always been aware that there was something very special in our bond with dogs, more intense than with any other animal. No other animal loves us in quite the same way as dogs love us. And it is mutual. Is it possible that we developed the capacity for love, sympathy, empathy, and compassion because of our long association with dogs? In "The Dog Who Couldn't Stop Loving", Masson considers the far-reaching consequences of this co-evolution of dogs and humans, drawing from recent scientific research. Over the past 40,000 years a collective domestication has occurred that brings us to where we are today - humans have formed intense bonds with dogs, and the adoration is almost always reciprocal. Masson himself has experienced a profound connection with his new dog Benjy, a failed guide-dog for the blind, who possesses an abundance of inhibited love. But Masson knows that the love he feels for Benjy - and that Benjy feels for all the people and animals around him - is not unique, but is in fact a love that only dogs and humans possess. With wisdom, insight, and a brilliant analysis of recent scientific research, the bestselling author delivers a provocative and compelling book that will change the way we think about love and canine companions.
