Lost dog: Cream beagle mix with red collar

I lost my cream beagle-mix yesterday around 5:30pm near the Augusta Common, just off Broad Street. He's a medium-sized dog, about 30 pounds, with a faded red collar and a tiny bone-shaped tag. He has a white patch on his chest and looks friendly, but he gets skittish when he's away from me. This dog is my kid - I've had him since he was a puppy, and he holds sentimental value. I'm really worried and just want him home safe in Augusta.
