Golden retriever mix with blue collar

Hey, I lost my golden retriever mix yesterday around 3pm near the Broadmarsh Shopping Centre in Nottingham city centre, by Canal Street and Maid Marian Way. Milo is about 22 inches tall with a golden coat, a white chest patch, and a blue nylon collar with a brass name tag that reads MILO. He has a small scar on his right ear from a playful tumble. I'm really worried—he's super friendly but tends to bolt if he hears fast footsteps, and he means the world to us.
