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.
