Not the owners, the dogs...............
Your viewpoint is as poor as those who blame guns for killing.
As much as people like you love to blame the breed or sub breeds it's vile human beings that have turned them into what some of them have become.
Blamed the scum not the dog, though it's innocent humans who suffer and the dog that has to pay, as far as I'm concerned the scum that do this to a dog, if the dog must be euthanized for an attack the owner should be too!
