The narrator, Tiger, a superbly intelligent canine, lives with Justin and his family. He was born with an unusual intellect. He has the gift for understanding human language, remembering past events, matching colors and shapes, and showing gratitude and love with amazing clarity. In the early part of his life Tiger is naughty, disobedient like any puppy would do. He regularly stole neighbor's expensive shoes, killed a pet rabbit, broke into neighbor's house and stayed out in the night when the neighborhood lake flipped. He does a turnaround after being given away by the owners and starts living in a farm - and eventually did something astonishing to become a town's hero. This book is based on a true story.
