'The Possibility Dogs' by Susannah Charleson

From the publisher: Charleson journeys into the world of psychiatric service, where dogs aid humans with disabilities that may be unseen but are no less felt.

This work had a profound effect on Charleson, perhaps because, for her, this journey began as a personal one: Charleson herself struggled with posttraumatic stress disorder for months after a particularly grisly search. Collaboration with her search dog partner made the surprising difference to her own healing.
