Usually seen tweeting about music, politics, and social memes, Penny Lane is a Pomeranian/Maltese mix owned by Susan Sarandon. As we know, pet friends have a lot of personality. In 2013, Susan Sarandon appeared on Late Night with Jimmy Fallon and announced her Penny could no longer stay quiet. This lead to a very active Twitter account run by the puppy herself.
