Golden retriever mix with red collar, lost near library

I lost my golden retriever mix, Scout, yesterday around 3pm. He's a medium-sized guy, about 60 pounds, with a reddish-gold coat and a white patch on his chest. Scout is wearing a bright red collar and has a blue bone-shaped tag; he's also microchipped and has a small scar on his right hind leg. Last seen near the Valdosta Public Library on North Ashley Street, heading toward downtown. I'm really worried - he's super friendly but tends to wander when excited, and he's part of our family. If you found him, please text me asap so we can bring him home.
