The dog-human bond is the most extraordinary cross-species friendship on the planet. Dogs give people so much: affection, companionship and profound emotional support. Now, more than ever, we can see the clear health benefits of living with a dog by our side. Drawing on science, research and in-depth personal interviews, Good Dog demonstrates how vastly a dog can improve our mental and physical health as well as our quality of life. Kate Leaver begins by telling the story of how she met her beloved rescue shih tzu, Bertie, and how powerfully he helps her through periods of depression. Then she meets 10 other remarkable dogs who've changed human lives - from Missy the pug, who helps 11-year-old Cody live his best life despite his autism diagnosis, to Pip, who helps her teenage owner manage diabetes, and Jingles, who works with inmates in a prison. With each story, it becomes more and more obvious how profoundly dogs can support us, comfort us and even save our lives.
