This beautiful and touching book, through a series of 41 interviews, tells the stories of dogs working in assistance roles, helping their human friends when they are most in need. The dogs in these pages have both saved lives and allowed lives to be fully lived, and the ripples of their goodness spreads far beyond their specific roles. These are the tales of courage and heroism, but above all they are love stories showing the remarkable things that can happen when bonds of friendship run deep.
