There is something wrong with people who are attracted to these monsters. They aren't pets. They need to be eradicated, full stop. We don't let people keep full-grown lions and tigers just because they like them; this is no different.
The "deed not breed" brigade are making fools of themselves. Everyone with half a brain can see that these overbred, fucked up creatures are about intimidation and violence ffs. If you own one you've got something fundamentally the matter with you.
Also agree with the pp who said that ALL dog ownership should involve a licence which you have to actively qualify for. There are too many dogs, too much shit everywhere and too much nuisance behaviour, it's reached the point where something needs to be done.
