This Pomeranian’s a bona fide star. He has his own Facebook page – with over 5 million fans -- and used his online popularity to produce two picture books and his own line of toys and also secure product endorsements.

Ahead of the holiday season, Boo has posted a video of a Christmas adventure with his brother Buddy. Check out these photos of Boo and Buddy, and more photos of Boo in San Francisco.
