Has your dog ever helped you in any sort of way?

I have a german shepard called boley and he saved my life. without beating around the bush im a rather large man and when i fell back in my enclosed garage last winter i ped out and when i came to i couldnt get back up by myself. it was a bitterly cold night and i was there until the following morning, thankfully Boley knew i was in trouble and lay across me the whole night to keep me warm. i owe him my life =]
