A rescued dog turns out to be a heroe as well as a villain, but whose fault is this? His master's? A sort of Cruella's living with them? Or-and the community? Yet, the mixed Border collie senses potential danger to his master! Are humans cruel by having this type of dogs living in a city? From multiple points of view the book depicts a dog's errands for 16 years to enable his master to see much more than what he was able before he came into his life as a street puppy.
