Horrific update in case of young woman ripped apart by her own Rottweilers as doctors fight to save her limbs: Onlookers reveal details of mauling as calls grow to restrict dangerous dog breeds

Doctors are fighting to save a 31-year-old woman's arm after she was mauled by her two pet Rottweilers in a vicious backyard attack. 

Western Australian woman Nikita Piil was in the backyard of her home in Success, Perth, when her dogs Bronx and Harlem attacked her at about 4.30pm on Saturday.

She suffered serious injuries to her arms and leg and remains in a serious condition at the Royal Perth Hospital.

She will likely undergo surgery to save one of her arms.

Neighbours were alerted to the attack after hearing Ms Pill's painful screams and tried desperately to stop the dogs. 

Neighbours tried to stop the brutal attack by banging on the fence and spraying the canines with a hose but could not stop the dogs from mauling Ms Piil.

Neighbour Bryn Spencer said he and another person heard Ms Piil's screams for about 10 minutes before they tried to intervene.

Mr Spencer said he tried to stop the attack but could not access Ms Piil's backyard without putting himself in danger. 

‘I was contemplating jumping the fence and getting in there to rescue her but obviously there were two Rottweilers in there … I would have been ripped apart,' Mr Spencer told the ABC.

‘All I could really do was watch this girl get mauled apart while I was smacking the fence with a bat … while (another neighbour) was hosing the dog.'

Police were forced to shoot one of Ms Piil's dogs to stop it attacking her and the animal was later euthanised

Ms Piil suffered serious bite wounds to her arms and legs and was rushed to hospital, where she is a serious but stable condition

Mr Spencer said he pleaded with police to shoot the dogs because the pair were ‘going to kill her'. 

Ms Pill's screams can be heard on footage captured at 4.45pm when police arrived at the property.  

Officers first tried to taser the dogs but that did not stop the attack.  

The attack ended when police shot seven-year-old Bronx, after determining the dogs were ‘extremely aggressive' and Ms Piil's life was in danger. The dog was later euthanised by vets.

Ms Piil's other dog, four-year-old Harlem, remains at a City of Cockburn facility while police investigate why the pair attacked their owner. 

Ms Piil was rushed to the Royal Perth Hospital where she remains in a serious condition. 

The young woman suffered major blood loss and serious bite wounds to her limbs and requires surgery to save one of her arms. 

The avid Rottweiler lover, who once described her dog Bronx as her ‘whole world – loyal, intelligent and protective', requires surgery to save one of her arms. 

Ms Piil’s Facebook page is filled with photos of herself with her pet Rottweilers. 

One photo, from 2019, shows Ms Piil cuddling with a Rottweiler – however, it is unknown whether it is the same dog involved in the attack. 

The young woman also had a sign plastered on her front door which read: ‘Beware of the Rottweiler'.

Four dog breeds are restricted in Western Australia including Argentinian and Brazilian fighting Dogs, the Japanse Tosa, Pitbull terrier breeds and the Presa Canario. 

Rottweilers are not a restricted breed in Australia, however the breed does have a reputation for having an aggressive temperament. 

The breed are slightly longer than tall, ranging in height from 56 cm for a small female to 69cm for a large male and weigh between 36 to 60kg. 

A 2022 report by the Sydney Children's Hospital revealed Rottweilers ranked third for the most reported attacks on children. 

The data took account of 628 patients who presented with dog-related injuries from 2010 to 2020 and found their average age was just five-years-old.

The breeds involved in the most reported attacks were Pitbulls with 10.3 per cent, followed by Labradors with 8.5 per cent and Rottweilers with 6.8 per cent.
