Found tan retriever mix dog with green collar

I found a medium-sized tan retriever mix this afternoon around 2:15pm behind the Walmart on Main Street in Clovis. It's got a bright green collar with a small brass bell, and a little white patch on its left front paw. One ear flops while the other stands up, giving him a curious, friendly look. He's well fed, well groomed, and eager to follow a person's voice, so I sat with him in a shaded spot until he calmed down. I know how nerve-wracking it is to lose a dog, so I'm hoping to help reunite him with his family—if you're the owner, email [email protected] with any identifying details or your dog's name or microchip info so I can get him back home soon.
