An angry dog owner says he is scared a child will be killed by an out-of-control dog which attacked his Labrador in a busy street.
The man, who wishes to remain anonymous, said: "I read an article in the Gazette about a dog attack a couple of weeks ago - we had exactly the same happen to us.
"We were walking down Yiewsley High Street last week, outside Tesco's, and there were two young girls holding an English Bull Terrier on a lead, and it was snarling.
"It got free and came and attacked my dog, breaking his toes. He's now in a plaster cast and can't walk anywhere."
Police are limited in the action they can take regarding such incidents. Dogon-dog attacks carry no criminal charges, which has angered the victims of the violent dog.
The West Drayton resident said: "There really must be some kind of consequences for the owners.
"Our dog is only four months old and we're worried this will scar him for life.
"That dog is a big muscular thing and it just savaged ours.
"I had real trouble pulling him off. "The dog is well known around here; every time we turn the corner we are worried we're going to see him.
"The thing is, it could be a kid next time.
"Are they going to wait until a child dies before they do something?
"There is a metal sign outside a shop in the High Street which has massive bite marks where this dog just went berserk. It's scary."
Hillingdon Council confirmed its officers had attempted to make contact with the owner of the dog, but have so far been unsuccessful.
Police say if a criminal complaint is made, an Anti Social Behaviour Order can be placed on the dog owner, which would allow a fine to be issued if the problem dog is found not on a lead.
