In the sequel to "Sadie Sapiens", Sadie, a tiny Chihuahua who's learned how to communicate, enjoys a tight bond with her pack of humans at the Institute for Non-Human Intelligence.

She wonders if they still live. Are they also intelligent? Mix in a colony of self-organizing dogs that want to be left alone and humans that hate them. Ruff.
