Families living on a Pinner estate are fearing for their children's lives after two youngsters were savagely mauled during vicious dog attacks.
Jordan Wright, nine, is the latest victim of a Japanese Akita which lives with its owner in Hazeldene Drive.
The youngster had returned home from West Lodge Middle School when the dog pounced, ripping flesh out of his hand, arm and chest.
Three years ago the same dog sank its teeth into 10-year-old Maria Molodyhh's head, resulting in her needing 92 stitches around her face. Her mother, Jalina, says Maria has never fully recovered from the ordeal and is outraged the dog was not put down after the first attack.
Mother-of-two Mrs Molodyhh, a piano teacher, said: "The dog just jumped on her. She needed two operations. We took the owner to court and Maria was compensated with £750, but nothing happened to the dog.
"Maria still has nightmares about the attack. When I heard another child had been hurt it made me so angry. It is clearly a dangerous animal but nothing has been done about it."
Jordan's furious mother, Amanda Cope, spoke of the moment she found her injured son. She said: "I could hear Jordan screaming and ran to see what was wrong. He had been helping the dog's owner with her gardening, and offered it a biscuit.
"The dog just leaped on him. There was blood everywhere, Jordan's flesh was hanging off. He was crying and screaming and in complete shock."
Jordan was taken to Northwick Park Hospital after the attack on September 10 and transferred to the Royal Free Hospital, where he needed stitches and skin grafting.
The football mad youngster, who is just 4ft tall, has been left with puncture mark scars across his chest and right bicep and a badly scarred hand.
His mother said: "That dog is a brute. The kids on the estate are scared of it. If a human attacked someone they would be dealt with by the police. So why isn't it the same for an animal?
"My son is scarred for life, but next time a child might not be so lucky."
The mother-of-three has started a petition in her neighbourhood campaigning for the dog to be destroyed.
The Japanese Akita is also known as the Akita Inu. The name means large dog, and it was originally bred for fighting.
A spokesman from Harrow Police said: "We explained to the boy's mother that the dog in question is not designated as a prohibited one under the Dangerous Dogs Act.
"Therefore, as the incident took place on private property, legally we are not able to take any action against either the dog or its owner.
"We understand from conversations with the mother that a dog warden from Harrow Council has been in contact with the boy's mother and has discussed what other actions could be taken, including pursuing the matter through civil courts."
