Cream Labrador mix with blue collar

Hey, I lost my cream Labrador mix yesterday around 6pm. We were walking near the Guildhall on Market Street in Winchester when he slipped his collar and bolted toward the park on the far side. He’s about medium build, yellowish cream coat, floppy ears, and a bright blue collar with a small brass tag that reads 'Benny'. He has a distinctive white patch on his chest and a tiny freckle above his right ear. Benny is really anxious without me and this dog is more than a pet to me—he’s my hiking buddy and the search has me worried, please get in touch if you’ve seen him.
