OMG that's a dreadful thing to read @Littletreefrog, what a dreadful experience for everyone involved. Dreadfully sad for all who had to see that, and the poor man that was attacked too. It might sound terrible but the person who did what he had to do, was incredibly brave to get that close. There was no choice in the matter.
Hands up there are some lovely ones out there, I have met many of them, do I trust them? Not on your life, would I have one? Nope again.I have worked with animals and had animals all my life, but no thank you very much.
They seem to turn very quickly from lovely dogs into killing machines, it's like something switches in their brain and off they go. My friend had one and it did exactly the same thing and had to be pts ( turned on her but never got the chance to cause any damage) she got rid asap.
Just shocked me that he turned like that for no reason, so I'm totally against people having them in a family home around children.
I hate thinking of a mass cull of any breed, but it will be needed as the pounds and shelters here are full to the brim of them, and they cant be rehomed, so they have nowhere to go. Pounds and shelters can't keep them forever, its simply impracticable so they will need to be culled.
