Agreed. Drives me nuts when people want to minimise it as just 'bad owners'.
This is what these dogs do. It is what they are.
Yes, you could say that owners drawn to these kind of dogs may have issues themselves but I doubt that they are so psychopathic that they are anticipating they or their children or anyone else being mauled to death and not caring.
They are likely not that bright or just have a false sense of confidence in their dog and their skills as owners.
90% of the time with fatal dog attacks on owners or their DC you hear the same thing "the dogs seemed gentle and loving, the owner seemed to know what they were doing. Something must have happened to set the dogs off".
And yes, something set the dogs off. Too much noise, too hot, feeling unwell, being over-stimulated, someone touching them in the wrong way, a bee sting, something moving too quickly which triggered them, something something something.
The point being that you could be the best owner in the world but once an attack/fight dog gets triggered to attack, which no owner is ever in control of - people get seriously harmed or killed.
And by then it's too late.
