Nick Trout is a big believer in the healing power of man's best friend, and living with what he calls a "positive canine philosophy on life.” That’s the message at the heart of his latest book, "The Wonder of Lost Causes," which tells the story of Jasper, a young boy with cystic fibrosis, and the support dog that helps him through it.
