I think a woman owned the dogs, and ran off when they attacked the girl.
Very sad.
I do understand this annoyance of chavs owning these type of dogs and using them as a status symbol, but in this case, I'm going to guess the daft cow that owned them had them as protection from scrotes on the estate.
A lot of comments about the authorities should take control, just what we all need, a new law stating how many and what kind of dogs folk can own
I think you should be accountable for your dogs, no other laws needed.
