Beagle mix with tan coat, lost near Carytown

I lost my beagle mix, Niko, yesterday around 3pm. He is about 28 pounds, with a short tan coat, white chest, and a tiny white patch on his left paw. He is wearing a blue harness with a reflective stripe and a bone-shaped tag reading 'Niko'. I last saw him by the VMFA parking lot off Cary Street in Richmond, and he wandered toward the Carytown shops on West Broad Street. This dog is my best friend; I rescued him as a puppy, and he means the world to me. If you spot him, text me right away--I'm really hoping to bring him home tonight.
