Tiny brown terrier mix with red collar

I lost my dog Scout yesterday around 6pm after we were near the Lake Charles Civic Center on Ryan Street. He's a small brown terrier mix, about 12 pounds, with a bright red plaid collar and a silver name tag that says 'Scout,' and one ear that flops a bit. There's a white patch on his chest and he'll probably shy away from strangers, which makes this extra stressful—he's been a gift from my grandmother. If anyone spots him, please text me or call, I'm really hoping to bring him home today.
