I went to a dad-daughter summer camp a few years back with Paige. They had a bunch of Alpacas there. They also had a big, white fluffy dog that basically lived with the alpacas. I wonder if it was a Great Pyrenees, keeping predators away from them.Yes, they are. They have been known to kill packs of coyotes. They love kids and are extremely gentle and protective. I dare anyone to mess with my wife or kids with them around. I can guarantee it wouldnt be good for them.
