A man has died after being attacked by a pet dog in Mill Park.

Police were called to a house on Ancona Drive about 6.40pm on Wednesday following reports a man had been attacked by a dog.

They arrived at the scene to find that the man, aged in his 60s, had died and that a woman had been seriously injured.

Police fired shots to stop the dog from continuing to attack the woman.

The dog, which is believed to an American Staffordshire terrier, was contained in the house and a Whittlesea council ranger was called.

The woman, believed to be in her 60s, was taken to hospital with serious injuries.

The dog is believed to belong to a family member.

Whittlesea council partnerships, planning and engagement director Liana Thompson said the dog was not registered in Whittlesea and there had been no previous reports to council about the dog.

“This is a terribly sad situation and we offer our deepest condolences to the family,” she said.

“The dog was euthanised [on July 10] and the council will continue to assist Victoria Police with their investigation.”

A neighbour told 3AW the man was a disability pensioner who used a wheelchair and would regularly stop for a chat with neighbours on his way to a nearby supermarket.
