An elderly woman has died after she and her husband were attacked by their pet dog at their home in Sydney’s southwest.

Emergency services were called to a home on Hornby Street in Wilton on Thursday at about 1:30pm.

They found a 74-year-old man and a 72-year-old woman suffering lacerations and bite marks.

The elderly couple were both treated at the scene and taken to Liverpool hospital but the woman later died from her injuries.

The dog has been seized by Wollondilly Council Rangers.

A report is being prepared by the coroner and inquiries are continuing.
