This is what the breeder who introduced the breed in Australia told me about the previous stud she had and what she is now breeding: "With him i was constantly scared for peoples safety as he could do a lot of damage. With these dogs i am a bit more relaxed".

I think that a confident dog will not cause harm out of nothing, and will not be confrontational unless there is a need, because of the confidence the dog won't be scared and will have nothing to prove. Of course, these are only thought based on my limited experience; I am not an expert in K9 psyche :)
