Beagle mix with blue tag, lost near Civic Center

I lost my beagle mix, about 2 years old, yesterday around 4pm. He’s a small beagle, around 25 pounds, brown and white with a tiny black spot on his left ear and a bright blue bone-shaped tag that says Nova and has the number 555-0142. We were near the Lake Charles Civic Center and the lakefront boardwalk by the fountain behind the performing arts center when he slipped his harness and bolted after a squirrel. I’m really worried—he’s a rescue and means the world to me; if you’ve seen him or picked him up, please help me bring Nova home.
