I have, but noticed allthe dognapings!

We live in a rurul comunity, and have never had a dog naping any where around here! I lock the doors, for sure! He is always in his soft carier, and this winter, I have a blanket to put over it! If it real cold, he stays home! I just want him with me, I am afraid he wil get hurt home alone- he has never ben home alone!He would freak!
