Baby Kamillah, who was mauled to death by a Rottweiler in northern New South Wales yesterday, has been remembered as a "beautiful angel” that was "loved and adored by so many".

The 12-month-old girl was tragically killed while visiting her grandmother who was moving into a new home when the family's dog attacked her in Inverell at 2.20pm.

According to the girl's aunt, Kamillah was being pushed in a pram by her mother when they were attacked by the dog.

Neighbour Ron Connors said: "I saw an ambulance officer run out with a child in his arms. It was very traumatic at the time for the family."

Kamillah died on her way to hospital after emergency services found her suffering critical injuries at a home on Greaves Street in the country town.

The Rottweiler was found in the home's backyard and was seized by council rangers.

The family owned a number of dogs, posting photos online.

Today, police have confirmed the animal belonged to a member of the family.

However, overnight, the girl's aunt took to Facebook to explain the dog was "not our family's".

"She was actually being walked by her mother in a pram on the way to her granny's house just one block away," Ida Boney wrote.

"There are no words to describe a scene where a mother is fighting with every ounce of her being to save her baby girl.

"The dog in question actually cleared a fenced yard - someone else’s dog not our family's.

"I really don't care what the breed of dog it was. Our family have lost our baby girl who never got a chance to live her life."

A GoFundMe page has been set up by a close friend to raise money for funeral costs.

Julie Parker wrote on the crowd-fundraising page: "Such a sad, sad loss of such a beautiful baby."

"It's just such a tragic incident. It's unimaginable and really sickening," Inverell Shire Council Mayor Paul Harman said.

"Sometimes dogs turn for whatever reason we don't know and I know as family you always need to be sort of vigilant."
