What is it that dogs have done to earn the title of “man's best friend”? And more broadly, how have all of our furry, feathered, and four-legged brethren managed to enrich our lives? Why do we love them? What can we learn from them? And why is it so difficult to say good-bye? Join B.J. Hollars as he attempts to find out—beginning with an ancient dog cemetery in Ashkelon, Israel, and moving to the present day.

Hollars's firsthand reports recount a range of stories: the arduous existence of a shelter officer, a woman's relentless attempt to found a senior-dog adoption facility, a family's struggle to create a one-of-a-kind orthotic for its bulldog, and the particular bond between a blind woman and her Seeing Eye dog. The book culminates with Hollars's own cross-country journey to Hartsdale Pet Cemetery—the country's largest and oldest pet cemetery—to begin the long-overdue process of laying his own childhood dog to rest.

Through these stories, Hollars reveals much about our pets but even more about the humans who share their lives, providing a much-needed reminder that the world would be a better place if we took a few cues from man's best friends.
