It doesn't work that way recercare, you know. Breeds like CO, CAO and Sarplaninac, simply know what their duty is, it is written in their gene codes. The dogs that can't bond are eliminated from the pack as pups, or simply stay at home as guardians. One of legendary Sarplaninacs, called Sari, in his 9 years long life never went with sheeps to pastures. Durring the day, he stayed in his masters cabin and sleep, but every evening when sheeps come back from the mountain in to the barn with three other dogs, Sari is coming out and starts his guardin. Every night he circled around the barn and cabin in a mile wide circle and not even once failed to do his duty, and he killed more then 10 wolfs in his life, all at his night guards. He was the most precious dog of all four for his master. Usually there is one male and few females in pack that is guarding sheeps. Females are so called "alarming device" and they are usually the first that spots the enemy, and first ones that take some action and if they can't manage to overpower, the predators then the large male starts his show with the help of the females ofcours. Breeds like Shars, COs an CAOs are not the dogs that are moving far away from flocks in order to find and chase of the paredators , like to clear the path for the sheeps. They are staying very close to flock in order to defend it with all their power if some danger occures. So you see, they don't act like GSD or Border Colie, they are not trying to find the predators, they act more like profesional bodygards. If the danger is there, they will stand infront of you (or the flock) and defend and protect you and even risk their own life if it is neceseary. To go back on your example. If I had those three dogs that you have listed and the third one is best fighter, then yes, I woul go with him for breeding. Aleksa
