Justin Bieber's Killer Bodyguard Is Just A Big Puppy

Justin Bieber's bodyguard has been in a heated standoff with photogs and exchanged blows with cops; but he's just been given a tough new detail, babying the singer's new puppy.
Bieber isn't playing around when it comes to Esther -- the same adorable little Silky Terrier he wined and dined at Mastro's in Bev Hills on Sunday. He's put his top dog, bodyguard Michael Arana, on the job of protecting his precious pooch.
