An elderly woman has died after being attacked by her own dog in Wilton Thursday afternoon.
Rosemary O'Reilly, 72, suffered significant bite wounds and lacerations to her arms, legs and body when she was attacked by the large Staffordshire terrier-Rhodesian ridgeback cross at her home.
Mrs O'Reilly's 74-year-old husband was also injured in the attack.
Both were treated at the scene by paramedics and taken to Liverpool Hospital where the condition of the woman deteriorated and she passed away.
Chief Inspector Michael Bright, from Camden police, said the dog involved in the attack belonged to the couple.
"They've had it for three-and-a-half years and for some reason it attacked the two of them," he said.
Wollondilly Shire Council rangers have taken the dog, which is expected to be destroyed.
A council spokesperson said the fatal attack was "extremely upsetting to us and our community".
"Our thoughts are with the family and all of the first responders that had to manage this very distressing incident," the spokesperson said.
