We recently bought our nubian, and the breeder is selling Great Pyrenees females, adult. I watched the dogs, who were some distance from the herd when we arrived but when I stepped in with the goats the dogs were both there in a flash. They were friendly but watched every move I made with the goats, and one stayed glued to my side. She was nice, but cautious. I was very impressed. So, we are thinking of returning to the breeder and buying one of these girls. My question is, how well do adult LGD's move from one herd to another? She would be familiar with the nubian we just bought, but the eight boer does would be all new to her. I haven't seen any predators around here, with the exception of the neighbor's dogs that border the back pasture, but our girls will eventually have access to the back pasture and I can't see a lot of it from the house. So, a LGD makes sense and I like the idea of an adult with experience instead of a puppy. The breeder said this LGD also helps deliver the kids (how cute!). Anybody transplanted an adult LGD into a herd with good results?
