Gracie the hound has been spotted again, this time in Philadelphia, where the quirky indie actress is shooting a movie: "While browsing the Wilbur Vintage shop in the basement, Posey's dog showed an interest in shop owner Dan Wilbur's Stride Winterblue gum... Wilbur says that Posey asked him to chew a piece a little bit and then give it to Gracie because she loves to chew gum. Posey tried to retrieve the gum from her pooch, but Gracie swallowed it." Can someone call the ASPCA already? [Philly Gossip]
