A gang of teenage thugs are terrorising a suburban street in western Sydney, bashing a family dog to death and poisoning a neighbour's cat.

The campaign of terror has residents of Roebuck Crescent in Willmot living in fear for their lives and desperate to leave.

Grandmother Joanne Carter, 63, found her pet dog Rocky 'howling in pain' and covered in blood in her backyard last Thursday.

The 10-year-old Labrador-rottweiler cross had been pelted with bricks by the group of out-of-control teenagers, believed to be aged between 12 and 15.

Rocky suffered horrific injuries including multiple spine fractures from the attack that left him paralysed, and had to be put down.

But residents of the troubled street dotted with public housing said it was just the latest shocking act of animal abuse and youth crime, including fires and robberies.

Where the teenagers live is not clear, but the troubled street's woes are centered around two double-storey housing commission blocks at numbers 44 and 48.

The two buildings of five units are arranged on either side of a strip of grass locals call 'the paddock', with a third block nearby.

Several units are boarded up or have their fences bolted closed after being abandoned, with sun-damaged kid's toys and swing sets decaying in the front yards.

Walls are covered in graffiti, tins of paint splattered across the street, mattresses abandoned by the side of the road, and even moulding loaves of bread.

Ms Carter's daughter Deann Kalantzis said the shocking animal abuse was the work of a group of teenagers as young as 12 who were terrorising the neighbourhood

Ms Carter came home to her public housing home next door to the flats after frantic calls from neighbours about the attack on Rocky.

'Sweetheart I have some very sad news to tell you,' she wrote in a message to her daughter Deann Kalantzis explaining what happened.

'I got home to find him paralysed from his shoulders down. Kids had been throwing rocks and brick bits at him and they had caused this damage.'

Ms Carter rushed the stricken pup to the vet but was told there was nothing to be done and he had to be put down.

'I'm so f**king angry and upset. Cops say they can't do anything,' she wrote in the text.

She later told Daily Mail Australia: 'The cops won't do anything, [Department of Community Services] won't do anything, nothing will change'.

Yusuf Kasli, 72, and his wife Meral, 65, said teenagers stealing property was an ongoing problem on Roebuck Crescent

'Another time they took six wheelie bins from around the neighbourhood, filled them up and set them on fire,' Mr Roebuck said

Ms Kalantzis said the shocking animal abuse was the work of a group of teenagers as young as 12 who were terrorising the neighbourhood.

She said the juvenile delinquents had earlier killed another resident's pet cat with poisoned food and committed numerous other crimes.

'These kids run around doing this kind of senseless all stuff all the time,' she told Daily Mail Australia.

'They set fires, they rob houses, they kill animals... you can't put anything past these kids.

'I feel sorry for my mum. Animals are helpless it's just so wrong.'

Ms Carter's neighbours said youth crime including vandalism, burglary, and animal abuse had been an ongoing problem for years as groups came and went.

A woman named Sarah living in one of the two-storey public housing blocks said the teenagers had a history of mistreating animals.

Les Askew, 39, said he would occasionally see cars on fire and the teens roamed the street in groups causing trouble

She said about a month ago they tried to rip a Staffordshire terrier living across the street from her through a small gap in a fence.

'I heard the dog screaming and ran over and grabbed the dog and told the kids how disgusting they were,' she said.

'I brought the dog back over here until the owners got home.'

Sarah said the family moved out soon after in fear for the safety of their pets and children.

'They weren't copping that. They thought if they can do that to my dog, what might they do to my kid?' she said.

'I think [the teenagers] are jealous because they don't have a dog. Kids sometimes walk around with sticks poking and hitting dogs.

'The way some people around here treat animals is disgusting. We keep our dog inside, better to be safe than sorry.'

A few doors down the street, Yusuf Kasli, 72, and his wife Meral, 65, said teenagers stealing property was an ongoing problem.

'They stole furniture from our porch, from a lot of people's front lawns,' Mr Kasli said.

'Another time they took six wheelie bins from around the neighbourhood, filled them up and set them on fire.'

Even moulding loaves of bread were scattered by the side of the road alongside other rubbish

Mr Kasli said the problem had persisted for much of his seven years on the street.

His daughter Merve Kasli, 32, said she had experienced similar troubles from teenage gangs.

'They stole a couch from my porch and burned it in the paddock, they damage houses and vandalise everything,' she said.

'I'm afraid to walk around the neighbourhood and always go straight to my car when I leave the house.

'I want to move somewhere else but it's hard to get out and I don't want to leave my parents here.'

Les Askew, 39, is raising his family a couple of doors down from where the poisoned cat lives before the teenagers killed it.

The father-of-three said he would occasionally see cars on fire and the teens roamed the street in groups causing trouble.

'The kids have a mouth on them, a lot of profanity, you hear them going past all the time yelling f**k and c**t,' he said.

'I have nine and 11-year-old boys and if I heard them saying that I'd wash their mouths out with soap.'

Mr Askew said he wanted to get out of the area, where he doesn't let his sons and two-year-old toddler play outside his yard, but it was difficult to get moved.

His friend Sarah Allan, who managed to get out of Willmot several months ago, said Housing NSW refused to do anything about the longstanding problem.

'It's been going on for years, housing won't do anything about it. They had to move me, that's how bad it is,' she said.

Farther up the road there are decrepit houses and ramshackle fences

'Our stuff gets stolen, our houses get smashed up and robbed - even while we're asleep upstairs.

'It's not fair because there's good people here.'

Ms Allan said many residents lived in fear and wouldn't let their children play outside because the neighbourhood was too dangerous.

'You see the fires, broken glass, syringes, people living with graffiti all over their house, it's just atrocious,' she said.

'Housing know who the problem is and has no intention of doing anything about it.'

Ms Kalantzis also hit out at Housing NSW for not moving her out of the area after her children moved out and started their own families.

The mother-of-four said her Ms Carter had been waiting for a transfer to 'anywhere but there' for years and if she had got it, Rocky would still be alive.

'We all used to live together my brother myself and my mum but I had four kids and moved out,' she said.

'She's been there for over 10 years now in a huge three-bedroom house with a yard she struggles to maintain.'

Ms Kalantzis said she wanted justice for the beloved family pet, but police said they were powerless to act because there was no footage.

She recalled when she picked up Rocky from an animal shelter and he urinated on her leg as she drove him home.

'It's so sad the way you left the world I've been in tears all day knowing you're gone,' she wrote in a tribute on Facebook.
