It's amazing how often you hear a story like this. A blind man and his uncle rescued a German Shepherd by the name of Coda. Well, one night at home while the two men slept, they were awakened by Coda, who knew there was a very dangerous situation. Lawrence Perry, the blind man, woke up to what he knew was a fire breaking out. Amazingly, Coda woke up his Uncle Leo as well, before the smoke detector even started going off!
Both men credit Coda with saving their lives, as well as the house. Which leads to a famous question seen on many bumper stickers: Who rescued whom? :-)
