Golden retriever missing near Decatur Square

I lost my golden retriever yesterday around 3pm near the Decatur Square, by the gazebo outside the old courthouse on Church Street. He's about 60 pounds with shiny gold fur, a bright red collar, and a small bone-shaped tag that says 'Milo'. He has a white patch on his chest and a tiny scar on his left hind leg from a past adventure. He's friendly but tends to pull when excited, and I'm really worried, because he's been my loyal companion since I adopted him last year, and this dog means the world to me.
