Book excerpt: From a New York Times best-selling author, an important and heartfelt exploration into the world of lost dogs and the power of reunion One in six dogs go missing at some point in their lives, leaving bereft owners to search high and low, hang missing posters, check shelters, and hope for good news. But amid these grim statistics, countless happy endings are forged. Tails wag again. Best friends are reunited. In Where the Lost Dogs Go, Susannah Charleson, author of Scent of the Missing and a trusted chronicler of the human/animal bond, dives headlong into the world of missing dogs. The mission to reunite lost pets with their families starts with Susannah's own shelter rescue, Ace, a plucky Maltese mix with a mysterious past who narrowly survived months wandering lost. While Susannah formally studies animal behavior, lost-pet search tactics, social media strategies, and the psychology of loss, Ace also steps up for training. Cheerful and resourceful, Ace has revealed a nose for the scent of lost pets, and together they help neighbors and strangers in their searching. In Where the Lost Dogs Go, readers take to the streets beside Susannah to bring home a host of missing pets. Along the way, Susannah finds a part of herself also lost. And when unexpected heartbreak shatters her own sense of direction, it is Ace--the shelter dog that started it all--who leads Susannah home. Inquisitive, instructive, heartrending, and hopeful, Where the Lost Dogs Go pays tribute to the missing dogs--and to the found--and to the restless space in between.
