definatly something else going on here....
they dnot just attack for no reason.
cant dogs attack just by staring in their eyes or something?
Yes there does seem to be alot going on atm but like you say, once the media gets one story, loads of stories come in about it (think it could be too that the parents os the people know that they will be able to sell a sotry)
Personally i wouldnt have a rotti or staff...but even with a collie or labrador im sure that it could still happen.
