Humans and animals have assisted each other throughout history. Although most of the book is devoted to the ways dogs’ keen senses of smell and hearing contribute to locating lost people or ferreting out drugs, readers will also discover how horses, monkeys, and even birds play important roles in rescues. Included are timelines that show how animals have helped humans throughout history, colorful photographs of animal helpers in action, and glossaries and sidebars to provide additional useful information.
This covers many types of animals especially dogs. Focusing on a few types of rescue animals instead of so many might have given the reader an exciting focus for further research.
