Beagle mix with blue collar and red tag

I lost my beagle mix yesterday around 6pm near Mattoon Square on Main Street. He's a medium-sized dog, about 25 pounds, tan-and-white with long ears and a white patch on his chest. He wears a blue nylon collar with a red heart-shaped tag that has his name, Biscuit, and my number. I last saw him wandering toward the library and East Center Street; he's a little shy with strangers but super sweet once he warms up, and this dog means the world to me.
