You’ve seen them, walking with purpose through crowded concourses, waiting alertly at curbs, at special events--in every walk of life. Sometimes you glimpse them on the news, in areas that have been struck by natural disasters (building collapses, avalanches, earthquakes, mudslides) or touched by war—first responders who are put into some of the most dangerous and challenging missions on the planet. They are service dogs and working canines, or “Good Dogs of Service”. And they use their awesome powers for the benefit of people throughout the world, in every social stratum. In this book, photographer Lynn Cobb has given us privileged and candid access to twenty of these remarkable canines and their handlers. Her mission: to inspire others to love these dogs as much as she does and become their advocates.
