Gr 2-4-Large, colorful photos clearly show a variety of working dogs in training and engaged in their tasks. The simple texts are easy to interpret for reluctant or early readers and yet informative enough to provide a definition of the dog's duties and what is required from it to fulfill each job. Factoids on each page add additional information. Each title describes the animal's training and the expectations for its performance. Positive stories of heroic canines and their partners help relay the message on how important their roles are in helping humans. Breeds are only covered briefly in order to explain which ones seem to be best suited for a particular task or training. The message is how important these animals are in fulfilling a need as well as the rewards humans gain from their loyalty and dedication.-Sandra Welzenbach, Villarreal Elementary School, San Antonio, TX Copyright 2005 Reed Business Information.
