A Golden Retriever is being hailed a hero for leading an ambulance to its unconscious owner in north China. The dog's owner had collapsed in a small alleyway in Yuncheng, Shanxi province last Wednesday and local residents alerted emergency services. Dashcam footage shows the loyal dog waiting for the ambulance in the middle of the road before running away, prompting rescuers to follow it. One of the rescuers, Jiang Xu, told video news site Pear that the dog kept looking back at the ambulance to see if it was following it. Then it started running and leading the way to its owner Jiang said the man had passed out from drinking too much and had been treated in hospital. The owner's son is currently taking care of his father.
