I really hope he is just lost and they find him soon. If stolen, he will most likely be kept under lock and key to keep him from escaping and attempting to return home.

Also too bad that he is not "truly" home in an environment/locale that he maybe knows a little. It would be so much more helpful. Dogs in a strange environment will wander far and long looking for something familiar.

Make sure that they post flyers and ads far from the actual immediate area as he can wander quite far away. Good luck... he sure is a beauty.
