I had some golden laced polish when I was growing up. Mine were pretty sweet. I haven't had any since then, but my daughter had houdans. They were very docile and sweet. They were easy for her to catch (probably because they couldn't see her most of the time.)
I guess you can tell from my avatar that I love our great pyrenees. They do a wonderful job of protecting the livestock and the place. A word of caution, however, for anyone not familiar with the breed. The do bark at night. It is part of their protective routine. If that bothers you, or if it bothers a neighbor, it might not be the breed for you.
Also, they roam a long ways. They will chase a predator a long ways, and they patrol a very large area. If you only have a small acreage with a lot of neighbors closeby, they may not be appreciated by the neighbors.
Personally, I love ours. I've seen ours go after 5 coyotes. My sister has two and her GP's killed TWO ROTWEILLERS that had jumped her fence and were going after her boer goats. They are pretty awesome dogs. Very friendly and love attention, but very wary of strangers. One of our males is getting pretty old. He lays around, and gets up and moves like he has so much arthritis it's a chore just to get up.... until he smells a predator, then he is off like a rocket!
We had one litter, too, then we neutered our male and female. We kept one pup out of the litter. Runt. He was tiny compared to the rest. He is now the same size as the others, and does his job just like his Mama and Papa.
I sure wouldn't hesitate to get that little female pup of chicken danz if I was wanting one. Just because she is smaller doesn't mean she can't be every bit as good of a guard dog as the others.
