I found a stray dog and I told him to wait in my house in Whiterun. Well while I was out I get a message stating that my dog is going home. I go back to Whiterun and find him just hanging out. I can not get him to follow me or do anything but bark at me. So now I can't use the dog. But the good news is he does bark ALOT. lol. O joy

UPDATE: December 2-2011. for some reason the dog is now responding. After over a week (game time) has gone by.
