The dog started going wild in the middle of the night – and thus prevented a terrible tragedy

A Golden Retriever from Northern Ireland woke her owners in the middle of the night with unusual barking, allowing the wife to notice that her husband was having a cardiac arrest and perform CPR until paramedics arrived. After three weeks in intensive care, his life was saved, and the dog received the "Resuscitation Heroes" award from the British Heart Foundation.

A Golden Retriever named Polly, from Northern Ireland, prevented a tragedy when she woke her owner Hannah in the middle of the night with unusual barking. Hannah discovered that her husband Adam was not breathing and was having a cardiac arrest. She performed CPR for seven to eight minutes following instructions from the 999 emergency operator, until paramedics arrived. Adam was hospitalized in critical condition for three weeks in intensive care and recovered. Polly received the "Resuscitation Heroes" award from the British Heart Foundation. The bond between Adam and Polly remains strong, and their morning runs have turned into calm walks.
