Lost dog: greyhound mix with blue harness

I lost my greyhound mix, Scout, yesterday around 7:15pm near the Crabtree Valley Mall parking lot on Glenwood Ave in Raleigh. He's about 60 pounds, mostly grey with a small white heart-shaped patch on his chest, and he wears a blue reflective harness. There are two tags on him: a silver bone-shaped tag that reads 'Scout 1123' and a round paw-print tag. He has a slight limp in his right hind leg and tends to bolt when startled; this dog means the world to me and I really need him back.
