Dogs and horses can be more than just pets. They can work at important jobs helping police to keep the rest of us safe and secure. This book explores how animals work alongside police officers every day, all around the world. A police dog and handler are partners who depend on each other. Unlike most police units, they stay together twenty-four hours a day. The horse and rider in a mounted police unit are also a close team. The officer takes good care of the horse, and the horse has complete trust in the officer. Dogs and horses also work in search-and-rescue teams, helping to find people who are lost or injured in the wilderness or a natural disaster. With full-colour photographs, illustrations and boxes containing key items of information, each volume of Working Animals provides an attractive yet informative guide to how animals and humans work together.
