Detective Dogs: How Working Dogs Sniff Out Invasive Species

Gr 4-8–Stevens has crafted an engaging, accessible book about conservation dogs—working canines trained to locate insects, mussels, and plants that threaten natural environments. These dogs make conservation work more efficient for humans, and play a crucial role in protecting delicate ecosystems. Many are rescued from shelters, where the very traits that once made them difficult pets now make them exceptional detective dogs. Stevens clearly explains how the dogs are selected and trained, describes the detection process for various types of invasive species, and delves into the fascinating science behind how a dog’s nose works. The writing is concise and informative, making complex biological and ecological concepts easily understandable for young readers. Photographs and real-world examples further enhance the content, offering readers both visual appeal and context.
