A five-week-old baby boy has died overnight after being mauled by his family's American Staffordshire on the NSW Central Coast.
Emergency services responded to reports of a baby being mauled by a dog at a home in Kariong about 2.20am on Sunday.
Police officers from Brisbane Water Police District performed CPR on the baby and were later assisted by NSW Ambulance paramedics.
But NSW Police said in a statement the baby could not be revived and he died at the scene.
The dog, which is owned by the family and was registered, was seized by the council and will be euthanised in the coming days.
At the time of the incident, only the baby's parents were at the home and there were no suspicious circumstances surrounding the incident, police said.
A report will be prepared for the coroner.
Police will be holding a press conference about the dog attack later on Sunday at 10.30am.
"Our thoughts are certainly with the parents, the family friends and also the first responders involved," Detective Superintendent Darryl Jobson said.
"This is a matter of tragic proportions and it is subject to investigation, and we will be making a report to the coroner."
Woman dies after being attacked by 'pack of dogs'
The latest attack comes after a Queensland woman was also mauled to death by three dogs last month.
Police were called to Maryborough, north of the Sunshine Coast, on June 6 after reports a woman was being mauled by a pack of dogs in the yard of a home.
It is believed the dogs belonged to someone else and the woman had been taking care of them.
Despite the efforts of paramedics, the woman died at the scene.
She suffered serious injuries to her head, chest, and one arm, according Nine News.
The dogs, believed to be cross breeds, were corralled into a shed and have since been removed by the local council.
Speaking to reporters at the scene, Acting Inspector Wade Lee said it was a "tragic accident".
