I recently found a dog wandering around and I absolutely love him, my kids do too. We've put up posters and have asked around but no one has claimed him or knows where he came from. We live in a very small town where everyone knows everyone and their dogs, so we know he's not from around here. He had no tags, just a collar and he was dirty. I know that whoever had him before loved him because he is the sweetest, most loving dog I've ever met. We want to keep him but I don't want to be heartbroken if the owner shows up. We've had him for about three weeks and I'm already so attached but my heart breaks for whoever lost this special little dog too... What should I do?
