A mother and her teenage son were violently mauled after one of the family’s six American pit bull terriers escaped from their property in Sydney’s west.
Bloodcurdling screams were heard in the suburb of St Marys on Monday when mother Kim and her teenage son were attacked by the stepfather’s precious pit bull terrier Luna at around 11am.
Daily Mail Australia saw the teenager calling for help after the stocky dog sank its razor-sharp teeth into his left arm.
The teenager, with blood running down his forearm, fled the wild dog and sought help from a neighbor.
It’s the latest in a wave of brutal dog attacks across the country that animal behaviorist and veterinarian Kate Lindsey says are caused by “poor breeding practices,” leaving dogs more suffer from chronic pain.
Mother of 15-year-old attacked by their American pit bull terrier was caught in the crossfire

The 15-year-old (pictured right) suffered deep injuries to his forearm in the attack.

Police who attended the scene were forced to use capsicum spray to control the dog which attacked the boy and his mother.
Minutes after the attack, police cars rushed to the house, which has a dog run out front and piles of trash.
The 40-year-old mother emerged from her property with deep bites and scratches all over her stomach and back.
Both men were treated at the scene for their injuries by NSW Ambulance paramedics who wrapped the mother and son’s arms in bandages and took them to hospital.
Police had to climb through an open window of the house and separate the agitated dogs using capsicum spray.
Older sister Tahna said it wasn’t the first time Luna had attacked a family member – adding that the family at one point owned eight pit bulls.
“She bit me here (pointing to her left breast) and on the back,” Tahna, 18, told Daily Mail Australia.
“Maybe now (mom) has been bitten, she will have Luna put down.”
Tahna added that the family recently lost two dogs who were impounded after running away.
The RSPCA arrived at the home at 12.20pm where officers were able to speak to the dog’s owner while he smoked cigarettes on the front porch.
Inspectors left the property without removing any animals.
Nearby Chifley College Dunheved was closed until the dog was collected and placed in a fenced enclosure.

Another of the six dogs that live at the property briefly escaped before the owner was able to bring it into the house.

RSPCA inspectors attended the Maple Road property but did not remove any of the owner’s six dogs.

Dr Lindsey told Daily Mail Australia that poor breeding practices often leave large dog breeds suffering from chronic pain, causing aggressive behavior that has made headlines.
“I guarantee these dogs will have a history of anxiety or physical health issues,” she said.
“Pain is the leading cause of anxiety, especially aggressive behavior in large breed dogs.”
“In my experience treating 15,600 dogs with anxiety and aggression, the majority of large breed dogs exhibiting aggression have an underlying health problem that has gone untreated. »
“In all cases, the problem is resolved when the dog receives relief from pain and anxiety.”
Earlier Monday, a man was left fighting for his life. He was attacked by two Rottweilers in a violent attack which also killed a cat in Sydney’s southwest.
Emergency services were called to a house on George Road in Leppington, in Sydney’s southwest, around 7.30am on Monday.
A man in his 50s was walking when he was suddenly attacked by dogs that had escaped from private property.
The victim was bitten on the head, neck, arm and leg, while a cat from a nearby house was believed to have been killed by the dogs.
Nikita Piil, a 31-year-old Perth woman, had to undergo emergency surgery to save her arm on Saturday afternoon after rottweilers from the Bronx and Harlem began mauling her at her home in the southern suburbs by Success.
Horrified neighbors tried to distract the dogs, but it was only when a police officer was forced to shoot one of the animals that the attacks stopped.
The slaughtered animal then had to be put down.
An Adelaide man and his sister were seriously injured requiring surgery last Friday when their family dog, a Sharpei-Pitbull cross named Caliche, began attacking them during an argument at a Brompton home on Tuesday .
Clifford Newchurch, 42, was visiting family when the dog suddenly launched into a violent attack, latching onto his hand and tearing flesh with its teeth.

Perth woman Nikita Piil was mauled by her pet Rottweilers on Saturday, with police forced to shoot one of the animals to stop the savage.
After the family managed to distract the animal by pouring boiling water on it, the dog turned on Mr Newchurch’s sister Stella, 39.
After snatching the dog, family members locked it in a bedroom while the family fought to keep the door closed as the powerful dog tore through the wood.
The dog, which has been a pet for eight years, is at risk of being put down.
Dr. Lindsey said there was no such thing as an “aggressive breed,” only aggressive individual animals responding to what they perceived as the causes of their suffering.
“A dog is aggressive for a reason, there always has to be a threat,” Dr Lindsay said.
“Sometimes that threat is internal, they feel nauseous and that dog uses aggressive behaviors to feel safe.”
“Or they just feel pain and think what’s causing the pain?”
“It must be this person or that person, until they started patting me, I didn’t feel any pain.
“Rottweilers can be the most affectionate dogs when they are not in pain.”

Perth animal behaviorist and veterinarian Kate Lindsey accuses dodgy breeders of producing animals with defects that lead to aggressive behavior.
She said questionable breeders of rottweilers and pit bulls were producing dogs with multiple illnesses and that treatments sometimes only made the behavior worse.
“Due to poor breeding, the majority of Rotties suffer from chronic pain from the age of two in the form of degenerative joint disease,” Dr Lindsay said.
“Pitbulls have lists of hereditary diseases, including hip dysplasia, cross diseases, endocrinopathies and chronic skin inflammations.
“They frequently start taking prednisolone, a steroid that exacerbates aggressive behavior.”
She said breeders who failed to screen for congenital problems but “culled” dogs must be held accountable for putting people at risk.
“None of these breeders suffered any consequences for the problems caused by the aggression resulting from the physical problems the dogs were born with.”
