Indeed, there are intuitive or instinctual behaviours different breeds have - of course they can learn other behaviours from observing other dogs, and training can reduce or suppress instincts to some degree as well. Context matters too, so if the environment doesn't match what their instincts would lead them to do don't have the opportunity to get triggered then you're not going to see them, at least not as often or as strongly.

The most obvious to me are the breeds that were bred for herding, and where you see that behaviour in mixes of that breed as well - even if it's muted some.

And I tend towards agreeing with you re: pitbulls. I've seen perfectly friendly and generally very gentle pitbulls snap - there's no reason for this amongst the general population.
