Happy (belated) Halloween, Beast!
Mark Zuckerberg celebrated the spooky holiday by giving his new pooch a big bone to pick to go along with his own Facebook page.
When he's not too busy picking up his pooch's poop, Mark posts super ADORBz photos of Beast on the dog's Facebook page.
Beast currently has 1.1 million likes so I'm pretty sure LOTS of peeps are happy about his new treat!
