Gray dwarf rabbit with blue harness missing near Riverwalk

I lost my gray dwarf rabbit yesterday around 3pm near the Riverwalk by the water feature off Main Street in Pueblo. He’s tiny, about the size of a soda can, with soft gray fur, a white underbelly, and a blue harness with a tiny silver bell that jingles when he hops. He has a small white dot on his nose and a faint notch in his left ear—that's how I tell him apart. He’s never far from me; this little guy has sentimental value, and I'm really worried about him; he might be microchipped. If you spot him, email [email protected] and I’ll arrange a pickup.
