A funny and moving middle-grade novel for dog lovers by popular author Mary Jane Auch. Other dogs are K-9s. But K-10 is a cut above other dogs, and his mother gave hime the name to prove it when he was a puppy. Now K-10 is grown up and all on his own, because K-10 doesn't need friends--canine or human. He spends his time running away from owners and doing time in dog shelters, and that's just fine with him. But after K-10 escapes from a shelter with some other dogs, everything changes. These new dogs aren't so easy to forget, and all they can bark about is finding old and new owners. Will K-10 go back to being a loner, or can this not-so-old dog learn a new trick--friendship?
