Lost dog: Brown Labrador mix with red collar

I lost my brown Labrador mix yesterday afternoon around 3:15 pm. He's about 60 pounds, with a red collar and a small silver bone-shaped tag, plus a white patch on his chest in the shape of a heart. We were near Old Town Plaza on San Felipe Street in Albuquerque when a street performer startled him and he bolted. I'm really worried—he's family and has sentimental value; if you’ve seen him, I can meet somewhere convenient and bring his favorite squeaky toy to help coax him out.
