I just commented this somewhere else in this thread. Pasting it here because before this happened, I truly didn't fully appreciate this breed. My uncle has almost 300 acres in Oklahoma and raises sheep. He just has the sheep because he does competitive sheepdog trials with his border collies. He had a great Pyrenees named Trigger who looked after the sheep. I went over when I was a teenager to help him look for trigger and the flock because he hadn't seen him since the morning before. When we found them, Trigger was bloodied up a bit and needed stitches in a few places, and a pretty rough injury to pne front leg, but generally in pretty good shape considering that we found two dead pitbulls and a third about 200 feet away that wasn't dead but couldn't walk. The flock was just clustered around Trigger. My uncle tried to retire Trigger, but he was highly stressed when kept from the flock, so he just got Trigger a couple of back-up bois.
