Straightforward book about a team of dogs who have been trained to scare bears to keep away from people and their dwellings in Glacier National Park, Montana, and its surroundings, thus saving the lives of bears as well as people. The color photographs are well integrated into the story, which is interesting and suspenseful at times---but not too suspenseful---and covers a lot of useful information. There are additional guidelines at the end about how to discourage bears. ( )
