Dogs save lives and protect property. They search for treasures and sniff out criminals. They guide people who cannot see and comfort those who are sick. Dogs Who Work is about all the important jobs that real dogs do every day. Along the way, you'll meet the breeds that excel in certain skills, from guarding priceless paintings or assisting police or gathering tennis balls! You'll even meet the mythological dogs who could fly or bring back the dead, and the famous dog who was elected mayor. This lavishly-illustrated book is a great introduction to all the dogs we love - and cannot live without.
