Yep, my pit bull/lab is a great protector. He was gone when we had the skunk attack, but never anything of the sort since. Hawks are a big problem for me (100% free range, but they have a coop and run, unlike some guy I know who didn't build a coop and couldn't figure out where his chickens went, sorry rambling now...) but they usually hang out around our house or in the orchard. So we've only lost one to a hawk, but they still make me run out waving my arms and yelling. (Shhh, don't tell the govt. but I have thrown rocks at a few and I never saw them again)
