But when a favor for a neighbor and his stinky canine companion unexpectedly turns into a bustling dog-walking business, Louis finds himself meeting an unprecedented number of new friends—both human and canine. Agatha, a quippy and cagey girl his age always seems to be telling two truths and a lie. Cyrus, a few years his senior, promises he’s going to show Louis how to be a better person, whether Louis wants him to or not. And then there are the dogs: misbehaving border terriers, the four (possible stolen) sausage dogs, the rest of Louis’s charges, and a mysterious white beast who appears at a certain spot at the edge of the woods.
Dogs and human alike all seem to have something they want to teach Louis, including his menacing older brother who keeps turning up everywhere. But is Louis ready to learn the lesson he needs most: how to stop being a lone wolf and be part of a pack?
