Canine Colony - Sadie Sapiens, #2

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. Surrounded by loving people who support her, Sadie is driven by a primal need to find her lost puppies. Puppies torn from her cage at a puppy mill and scattered to the four corners of the earth. 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.
