Council rangers have seized two pitbulls who stalked and attacked a woman while she was walking home from the shops.

The City of Stirling Council in Westminster, Perth seized the dogs soon after the attack on Saturday.

A decision on whether they will be euthanized will be made this week by a magistrate.

Residents of Lodesworth Road heard a woman screaming about 3pm on Saturday as she was attacked from behind by the dogs who had escaped through a gap in a backyard fence.

The woman, aged in her 30s, had earphones in as she walked and had no idea the pitbulls were there until they attacked and tore flesh from her leg.

The dogs, aged 2 and 4, let her go when she hit them in the face, Perth Now reported.

Neighbours rushed out to find the injured woman in the street.

She was taken by ambulance to Sir Charles Gairdner Hospital where she spent Saturday evening in a stable condition.

The dogs' owner, a young woman named Ashlee, gave a tearful apology to the victim as she was interviewed by 7 News.

'I'm so sorry,' she said.

'I did try (to) run out and go speak to her but everything was just so chaotic at the time - if there's anything I can do to help.'

Ashlee said the two dogs, named Terra and Mia, were gentle and let kids ride them 'like they're ponies'.

She choked back tears as she said they were the only family she had apart from her daughter.

'They're beautiful - they made me feel safe,' she said.

'They're great dogs, this is just a really s**t circumstance.'

Ashlee said the two dogs, which are normally chained, had never attacked anyone before.

But angry neighbours told reporters they had been living in fear of the dogs for quite some time and had complained many times to council before the attack.

One neighbour, named Suzanne, said she was chased recently.

Others said they detoured away from the house when walking to the shops to avoid the dogs.

One woman said council wouldn't take action until an attack.

'The council rangers say they can't do anything about it till someone's attacked,' she told 7News.

'Now someone's been attacked - hey - it's taken long enough.'

The attack comes a week after another woman was viciously attacked by two large dogs in the Perth suburb of Huntingdale.

Isabelle Ward had been door-knocking to promote a grocery delivery service when she was attacked in the dark.

She remembers seeing a woman holding two large dogs in one hand but could not make out the breed.

The first dog mauled her legs and the second ripped into her ribs causing lacerations and severe puncture injuries.

Ms Ward said she was afraid she would die during the attack.

'One of the dogs locked onto the back of my legs and was chewing on my legs,' she told 7News.

'I just remember the dog's face coming towards me – that's when I kicked it away.'

A week after the attack, Ms Ward was still struggling to walk.

As of Saturday the dogs remained on the loose with City of Gosnells council rangers searching for them.
