Lost tan and white dog with red collar

I lost my dog yesterday around 3pm. He's a tan and white medium-sized rescue mix named Scout. We were near the Brookshire Brothers on Main Street in Nacogdoches, Deep East Texas, when he slipped from his leash and bolted. He has a small white heart-shaped patch on his chest and one ear that's slightly folded; he wears a red collar with a metal tag that has my phone number. This dog means the world to me and I’d be incredibly grateful to bring him home soon.
