That's interesting. Our dogs have always been raised with the kids and the animals. They go out and protect the herd at night, then they will be in the yard for a sleep in the day. When we had two at a time, one would go out with the cows and horses at night, and the other would go out in the day.
We have quite a few wolves and a couple cougars up where my parents are. My brother was out along the fence line, he found a bunch of wolf tracks, and then he found Ruthy's trail (quite well worn) from the yard out to the horses (they are the farthest from the house). I prefer a dog that is good with people and the animals. But, that is just my preference. I am all for being best friends with all the animals that we own. Except the cow that tries to kill anybody that milks her. She is the exception to my rule.
Here is a site that my sister found when she first got her sheep last fall, and was looking into guarding animals.
Livestock Guardian Dogs at Work ? Another Side of The Great Pyrenees
It's incredible what these dogs can do. They aren't just the lovable pets that a lot of people see them as.
I just ask you to read the first page. Before I read it, I didn't know that the GP were that protective. And, they are around people a lot.
Our dogs are supposed to protect the farm and family. They have done that faithfully. And we have yet to lose an animal to predators (maybe the occasional chicken, because we had them free range out in the pasture, just getting locked up at night).
We have lost cows, horses, and sheep, due to our own ignorance, sickness, and other people's stupidity (I had a horse get shot by hunters), but so far never to a coyote, wolf, bear, or cougar.
