“Fun and engaging.” —School Library Connection “A fast, fascinating read that captures the strong bond between dog and owner.” —School Library Journal In this young readers edition of the New York Times bestseller, Cat Warren and her canine companion, Solo, teach readers that the nose knows no bounds when it comes to working together, being persistent, and helping others.Solo has a fine nose and knows how to use it, but he’s only one of many thousands of scent-detection dogs all over the United States. That’s a group that includes cadaver dogs, tracking, trailing, and apprehension dogs; dogs that can locate unmarked graves of Civil War soldiers; and even dogs that can find drowning victims more than two hundred feet below the surface of a lake. All these dogs love to use their noses. They think their job is simply the best, most interesting game they’ve ever played! What good working dogs can do may seem magical or mysterious, but What the Dog Knows shows the science, the rigorous training, and the skilled handling that underlie these amazing abilities.
