Query: Something's missing...

This book has a major omission. It claims to include "all important breeds available to dog lovers..." but, alas, the Pomeranian is not included. Why not??? Poms are the 10th most popular breed in the U.S. If the Entlebucher Sennenhund rates a page, then surely Pomeranians deserve a write-up.
