I'm sure it comes as no surprise that we totally love Boo around here. The Facebook sensation has got one of the cutest faces around and photographs like the celeb he is. Lucky for us, the time has come to spread the "Boo-tiful" wealth. His book Boo: The Life of the World's Cutest Dog is officially available! Also be sure to check out Boo's video trailer on the site. It's painfully cute. Check out some of our favorite shots from the new book of this sweet little guy going through his day and being overwhelmingly adorable.
