I totally agree. Mistrust is not a specific trait. It can be fear based or protection based. That is why some people prefer very social dogs because the odds of when they bite is not connected to fear. The other side of the coin is that some argue the breeds are becoming too social and loosing some of the edge that can be an advantage. That is why I prefer a dog with a higher threshold for defense but is not a social butterfly and has some protective instincts. Some very defensive dogs are strong and confident, especially with good training, but many are nervy and won't fight a man if the fight gets intense. The more extreme high prey super social Mals will stay in the fight because prey is such a lustful drive and that lust prevents fear and social dogs tend to have very good nerves. As I said, the issue is if you need a perimeter dog or property protection dog, many of those dogs will not be effective or need special training.
