put it like this, it's not really like how they are brought up. some dogs trust humans more than others no matter what, every dog is different and they say that all living land animals are 80% instinct and if you didn't have much trust in something\someone and your main instinct is to be defensive what else are you meant to do? they have a lock jaw and the head sway to tear you to shreds. sure it's the animals fault and people need to have more precaution on all dogs in my opinion. i think it's unfair allthough if they were reintruduced as being legal people would need to take more precaution.
