These dogs don't have shepherds though. They pretty much live wild with the flock. Well at least thats what I have read.
Yes, livestock guardian dogs work independently. As the name says, they guard their flock from predators.
Shepherding breeds are pretty much at the opposite end of the spectrum - they work closely with their handler (shepherd).
Breed traits are massively important when choosing a dog (sorry
@barrybd , I'm on my soapbox). We have selectively bred dogs over thousands of years to do particular jobs, like vermin control, shepherding, pulling, seeking, guarding, hunting etc. A few years of being pets doesn't eliminate those deeply rooted breed instincts. Please don't get a particular dog because X celebrity has one, or you saw one on Y TV programme and it looked amazing.
Don't expect, for example, a husky to be reliable off lead - their instinct is to run in a straight line and keep running.
There's a reason why we don't use terriers to herd sheep. It's not to say it can't be done but it will be a lot harder than training a collie that was bred to do just that.
I'll get my coat.
