War Dogs

In a new book, War Dogs: Tales of Canine Heroism, History and Love, Rebecca Frankel shows that dogs, with their legendary sense of smell, remain the best at finding improvised explosive devices. Frankel was given unprecedented access to America's canine heroes. She spent years visiting bases where the dogs are trained, meeting their handlers, watching their charges hone their detection skills. Here she talks about what happens when you don't earn a dog's trust, why these dogs appear to love their work, and what they do in their golden years.
