Dog detectives? Thanks to superior sniffers, some pups learn to help scientists investigate and track endangered animals. The snoopers’ clue? Poop. Dogs that are part of wildlife detective teams are trained to catch the scent of wild animal poop (scat) so that scientists can learn about these animals without luring or trapping them. Like many pooper snoopers, Sampson, the dog in this book, was once a shelter dog, too hyper and ball crazy for families. That energy and ball drive is what makes him such a good dog detective. He is trained on many species, from salamanders to bears, but his goal is always the same. Find the scat and get the ball!
