We really appreciate the below quote from the book Livestock Protection Dogs: Selection, Care, and Training by Orysia Dawydiak and David Sims.
"In Old World countries where livestock protection dogs have been traditionally used, lifestyles and farming practices are different than those we know in North America. Throughout Asia, the Middle East and the Mediterranean Basin, full-time shepherds are common. Sheep owners in a village often form communal flocks of sheep during the summer months when high country pastures can be used for grazing. Shepherd and livestock protection dogs accompany large bands of sheep to mountain meadows,. During these times when many protection dos are present, older dogs help to discipline and train younger ones. With one or more shepherds always on duty, undesirable behaviors can be spotted and corrected immediately. In this setting many stimuli act on a protection dog, including social interactions with other dogs. Boredom is unlikely to occur. If attacked or threatened by a predator, a protection do can reasonably expect to be backed up by his fellow pack members. He can also expect that a shepherd will be somewhere nearby, if not always in sight. …
Most North American farms would not fit into the scenario described above. Farms here have fenced pastures in lieu of open maintain rangelands. Livestock are moved abruptly from pasture to pasture, sometimes by truck.There are few full-time shepherds, goat herders, or cattle tenders. Protection dogs are often required to work along without aid or training from an experienced pack of peer dogs. Many protection dogs are initially placed with livestock that have learned to fear dogs. A significant part of the task of protection is having the confidence of the animals being guarded. North American guard dogs may be expected to develop their self-confidence with livestock that will run away from them or even show hostility. After a protection dog has gained the confidence of the flock or herd and has matured into a successful guardian, he is almost always left alone to perform what can be a very boring duty.
When such factors are considered, you may wonder why protection dogs transplanted from the tranquil mountains of Europe and Asia are able to work at all in the United States and Canada. Yet they do! The reason for their success is not so much the training techniques that are described in the succeeding chapters, but rather the highly evolved instincts of the dogs. If you have purchased a healthy protection breed puppy with an established guardian pedigree, he will probably become a good livestock guardian, in spite of any errors, you, the owner/trainer, might commit. In fact, you will never actually “train” your protection dog to protect. You will instead attempt to create an environment in which the dog is able to develop and express his inherited talents."
