A HEARING impaired woman is in hospital after being mauled by a neighbour’s pet dog in Perth's east.

The 55-year-old’s leg was so badly mauled she had to have plastic surgery and the retiree has spent the last two days recovering at Fiona Stanley Hospital

The woman who is partially deaf and has brittle bone syndrome, was bitten at least five times, relatives said.

Her brother, Nigel Abreu, said the family was angry the dog was not seized by council rangers until two days after the attack.

A decision is yet to be made about whether the animal will be put down.

"I want the council to destroy the dog it's a danger to the neighbourhood," he said.

The woman, who did not want to be named, was attacked on Saturday afternoon while gardening out the front of her Langford house.

The dog ran at her 92-year-old father who hit the French mastiff with his walking stick before it went for her.

"She dropped to the floor and tried to protect her neck and face, if she didn't the dog would have gone for her jugular,” Mr Abreu.

Eventually the dog's owner pulled it away.
