"If you want a friend in Washington, get a dog," Harry Truman once said. Perhaps that's why, for much of our Republic's history, there have been two top dogs at 1600 Pennsylvania Avenue--one with two legs, one with four. First Dogs, by distinguished journalist Roy Rowan and researcher Brooke Janis, tells the whole doggone story, from the days before there was a White House to Barack Obama's newly adopted presidential pup, Bo.

Here's a lighthearted romp through American history, packed with drawings and paintings from early America, plus photographs, starting with Abraham Lincoln's Fido. Not only did these four-footed goodwill ambassadors humanize their distinguished masters, they offered them a little unconditional love in a loveless town.

First Dogs gives dog lovers and history lovers a new angle on presidential history and is more fun than you can shake a stick (or rubber bone) at.
