Have you thought about putting an ad in the newspaper with a picture of him? I live outside of Springfield and one of my best friends lives in Pleasant Hope....I will pass this along to her. She had someone steal her 2 Labs last year and she knows many people in that area so she let EVERYONE know that she would not stop until her dogs were brought back to her! She came home from work one day and guess who was sitting in their fenced backyard....yep, her 2 Labs.
They were dirty and thin, but home and that's all that matters. She posted ALLLLLLLL over Facebook (and other places) and was constantly posting on there, "BRING MY DOGS BACK....I WON'T STOP LOOKING AND TALKING AND ASKING QUESTIONS UNTIL THET ARE SITTING IN MY YARD AGAIN!"
