"Super sniffer" dogs scent scat on land and at sea for scientific research. This examination of scat-detection dogs, who sniff out the feces of different creatures scientists study, begins with a fictional story based in reality. "Freddie" is saved from certain death in a shelter because he exemplifies two qualities essential in scat-detection dogs: high energy and the ability to focus. Beginning with the science behind what makes dogs such great sniffers, the book offers detailed text with lots of color photographs on glossy paper and sidebar photos with additional information. Background on how dogs began working in scat detection is followed up with information on training. Everything about these dogs is impressive. The stories of individual dogs (who often specialize in certain kinds of scat) are chronicled next, encouraging readers to connect to them as individuals. These dogs' stories take readers from mountain to ocean, desert, forest, and everglade.

Readers are sure to come away with a deep fascination with and appreciation for scat-detection dogs' essential contributions to conservation work. Why Wadsworth makes assumptions about the knowledge and feelings of students outside the U.S. who meet scat dogs and their handlers (perhaps a chance for a teachable moment) is questionable and perplexing, however. Cultural misstep aside, this is a great choice for dog and science lovers alike. (introduction, author's note, glossary, resources, sources, bibliography, index) - Kirkus Reviews Poop can be a legitimate topic of scientific inquiry, and with their canine helpers, scientists are using animals' feces to gather data and make conservation decisions for endangered species. The book begins with a fascinating look at the special training and important jobs that canines take on in order to help scientists in the field. Using information gleaned directly from dog-handlers, veterinarians, biological scientists, and researchers, Wadsworth discusses the amazing adaptive abilities of dogs' olfactory functions and what qualities make dogs the perfect fit for the job of sniffing scat.

Full-color photographs show dogs working in the desert, in the forest, and even on the open water, and reveal the synergy between humans and dogs. The narrative also emphasizes the lengths that scientists will go to protect endangered animals by studying their behavior patterns, their diets, and threats to their health. This book encourages readers to think about unconventional sources of information and the unusual methods of data collection necessary to scientific discovery. - Booklist.
