After a grisly search-and-rescue operation led to troubling consequences for author Susannah Charleson, she found that her relationship with Puzzle, her search dog, made a surprising contribution to her own healing. Inspired by that experience, Charleson learned to identify abandoned dogs with service potential, plucking them from shelters and training them to work with disabled human partners, to whom the dogs bring assistance, comfort, and hope. Similar to her best-selling first book, Scent of the Missing, Charleson’s The Possibility Dogs goes beyond the science that explains working canines to tell the stories of the dogs themselves. Like Merlin, a black Lab puppy who had been thrown away in a garbage bag and now stabilizes his partner’s panic attacks. And service dog Jake Piper, a formerly starving pit bull mix who went from abandoned to irreplaceable. This heartwarming combination of memoir and research is sure to both inform and inspire.
