One of my birthday presents was Bo, a stuffed toy version of President Obama's dog. It got me to thinking what it must be like to be First Dog. So I decided to read the whole First Dogs book. It was fascinating. So many presidents had dogs but only one had a Golden Retriever - that was President Ford's dog named Liberty. She even had little First Puppies. Isn't it nice that there have been two top dogs in the White House throughout most of US history -- one with two legs and one with four. Hail to the Chiefs.
