Is he even real? Yes, he is! Boo, the favorite of over 2.5 million fans on Facebook, is not an animated plush toy, but a Pomeranian, a type of dwarf Spitz, whose fur had to be clipped short because the long shaggy hair had become tangled and matted. The teddy bear look that has made Boo the "cutest dog in the world" is thus a result of chance. He made his first appearance on the internet in 2009 - that was more of a private joke. "My friends wanted to see pictures of him," says his American owner, who wishes to remain anonymous. Now, Boo is five years old, still looks like a puppy, and has long since captured millions of hearts and taken the digital media by storm worldwide. It's high time for his own book! Here it is - a collection of portraits and snapshots of Boo with his favorites.
