¿Perros detectives? Gracias a sus extraordinarias habilidades para olfatear, algunos cachorros aprenden a ayudar a los científicos a investigar y rastrear a animales en peligro de extinción. ¿Tras qué pista van? La caca. Los perros que son parte de los equipos de detectives de la vida salvaje están entrenados para captar el olor de la caca (excrementos) de los animales salvajes para que los científicos puedan aprender de ellos sin tener que atraerlos o atraparlos. Al igual que muchos cazadores de caca, Sampson, el perro en este libro, solía vivir en un refugio, era demasiado activo y alocado para las familias. Esa energía e impulso es lo que lo hace tan buen detective. Está entrenado para seguir a muchas especies, desde salamandras hasta osos, pero su meta siempre es la misma. ¡Encontrar la caca y capturar la pelota!

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!
