Beagle mix with blue reflective collar, lost yesterday

I lost my beagle-dachshund mix named Olive yesterday around 6:15pm near the Kroger on Caraway Road in Jonesboro. She's about 40 pounds, tan and white with a black saddle, and she wears a bright blue reflective collar with a small brass bone-shaped tag that reads Olive. She has a crescent-shaped scar on her right ear and a white heart-shaped patch on her chest, which are pretty distinctive. I’m really worried—she’s friendly but gets overwhelmed by loud noises, and she’s never far from me, especially on walks. If anyone finds her, I’d be incredibly grateful to get her back; she’s been with us since she was a puppy.
