According to the OP.
Anyone who owns one of these dogs will tell you it's more likely a warning bark (possibly even just excitement) than an aggressive intent to attack and kill his family.
Indeed, barking is simply a warning. Ddogs barking are just letting you know they are there, are excited, and telling everyone else that it is there territory (and is a sign orf poor training but it can be hard to completely eliminate).
Dogs that are aggressive with intent to harm/kill don't bark. Look for flattened ears, tail between legs, low stable stance, showing of the teach (gums rolled back), and a deep low growl, head low and possibly slow side-to-side movement.
If you don't have bare teach and a deep growl the dog is not going to attack!
