A 17-year-old girl has died after being attacked by a dog in Singleton, New South Wales. Annalyse Blyton was injured last Thursday, September 4, at a friend's home on Broughton Street. Emergency services were called to the scene around 11:30 a.m. after bystanders intervened to free her from the dog.

Annalyse suffered severe injuries to her head, neck, and body. She was airlifted to John Hunter Hospital in critical condition. On September 5, police confirmed that she had died in the hospital.

The dog involved in the attack was a 10-year-old mixed breed, described as a combination of boxer, bull Arab, and Irish wolfhound. According to Acting Superintendent Justin Cornes of the Hunter Valley Police District, the dog was in a fenced yard at the time of the incident.

"It should be noted that the dog was actually in a fenced yard at the time. This didn't occur in the street," Cornes said.

Following the attack, police euthanized the dog with the owners' consent. The owners have been cooperating with the ongoing investigation, which includes interviews with witnesses.

Six NSW Ambulance resources, including intensive care paramedics and the Westpac Rescue helicopter, were dispatched to the scene. Paramedic Josh Parfrey reported that bystanders and police provided initial first aid to Annalyse before the ambulance arrived.

"They were trying to stop some bleeding and keep the wounds covered," Parfrey said.

Superintendent Cornes expressed gratitude to those who helped Annalyse during the attack. "Certainly running into a scene where they didn't have full circumstances and to jump in there and remove the dog, which was at the time very aggressive, is incredible," he said.

Annalyse's mother shared a heartfelt message on social media, urging her daughter to keep fighting. "Fight with everything you have, my baby girl, don't let this defeat you," she wrote. She also thanked the first responders for their efforts.

A report will be prepared for the coroner as the investigation continues.
