How can dogs that sniff for excrement, urine, vomit, and mucus help protect animals from extinction? In the race to save endangered animals, finding solutions now is critical. Scat-detection dogs like Wicket, Tucker, and Orbee are conservation heroes and pioneers in a cutting-edge field of science. Canine detectives use their super sense of smell to locate the scat of target animals. From loose bear dung to gooey whale poop, scat can tell scientists valuable information about an animal’s sex, age, diet, and health—all without harming the animal or endangering the researcher.
