Yesterday at 10:30 am my wife and I were walking our shelties (miniature collies) when we were attacked by two large unsecured dogs , a lab and a full sized collie. This happened at east and bi state in Delmar. Our smallest sheltie male named Chocolate slipped his collar and leash and was chased off by the larger dogs. We are unable to find him after searching diligently . If any one sees him call Terry Dietrick at 302 245 7672 .He weighs 10 pounds is dark brown with black markings.
