The author draws from myth and literature, scientific studies, and the stories and observations of dog trainers and dog lovers around the world, to discuss the emotional complexity of dogs. But the stars of the book are the author’s own three dogs whose delightful and mysterious behavior provides the way to exploring a wide range of subjects–from emotions like gratitude, compassion, loneliness, and disappointment to speculating what dogs dream of and how their powerful sense of smell shapes their perception of reality.
