Black Labrador mix found near Walmart on Dewey St

I found a 2-year-old black Labrador mix this afternoon around 3:15pm. He's about medium size, maybe 60 pounds, with a shiny black coat and a small white patch on his chest. He was wandering near the Walmart on Dewey Street in North Platte, sniffing under cars by the curb, and he automatically came to me when I called 'Buddy'. He wears a bright red nylon collar with a blue bone-shaped tag, but no ID. He seems healthy and friendly, and I thought someone might be looking for him after he slipped away from a walk. If you know this pup, please DM me or call, I’d love to reunite him with his family.
