'Ingenious' dog hailed hero for saving elderly owner trapped in her home

A dog is being hailed a hero for saving the life of an 84-year-old grandmother in Sydney’s west.

Joan Irwin was trapped in her Blacktown home for 12 hours after falling over on Sunday about 4pm.

She could not get up or call for help before spending the night on the floor.

Her neighbours popped by to check in but were unable to get into the house.

Luckily, Ms Irwin was not alone. She had her Jack Russell Terrier, Princess, with her.

The 84-year-old attached her keys to Princess’s collar and the pooch sprang into action.

"She brought the keys through the little flap in the door and we were able to get in,” neighbour Peter Boros said.

NSW Ambulance paramedic Rhyse Vaughn said emergency services were “astounded” to find the dog was “the hero of the day”. He added “it’s absolutely amazing”.

“She was ingenious enough and young Princess was intelligent enough, and the super dog was able to go outside and give the keys away,” he said.

Ms Irwin will spend the night in hospital but Princess will probably be due a few treats when she gets home.
