An adorable pup is being hailed a hero for saving an 87-year-old woman from Minnesota's sub-zero weather.

Tim Curfman said his four-year-old black Labrador mix, Midnight, alerted him to his neighbor, Noreen, while they were outside on January 28.

Curfman said he was taking out the trash when Midnight 'had her ears perked up looking at me'.

'She doesn’t normally do that. Sometimes you get that feeling something’s up,' Curfman told WCCO.

Midnight then led her owner over to where Noreen had fallen on the other side of his house. He found Noreen lying in the snow and unable to get up.

According to Curfman, Noreen had been outside trying to fill her bird feeder when she fell.

'We figured she was out there at least a half an hour,' Curfman told the station.

He said Noreen's glove had gotten wet and 'she didn't have enough strength in her fingers to push herself up'.

Curfman said he rushed over to help Noreen and took her inside his home where his wife helped her warm up.

She told the station that Midnight definitely saved her life.

The weather was about -1F at the time of Noreen's fall. Noreen wasn't seriously injured nor did she have frostbite.

Minnesota was hit with a deadly polar vortex last week that caused schools and businesses to close, the US Postal Service stop deliveries in five states, power outages and the cancellations of more than 2,5000 flights.

The deep freeze has been blamed for 21 weather-related deaths across the Midwest.
