Cost effectiveness implies how much does the protection cost. Initial cost of dogs can vary wildly but the maintenance cost, especially when considering the two years to full protection usually exceeds purchase cost of dog. We have several LGD's here which includes Great Pyrenees, Ackbash (my favorite owing to speed and heat tolerance), Maramia x Great Pyrenees cross, and Old English Sheep Dog x Great Pyrenees cross. Those dogs are tasked with sheep and goats but operating cost are the same as they would be for poultry. The dogs and herds they protect are confined much the same way many of my birds are confined. The confinement alone excludes bigger threats such as dogs. The reality with the confinement is the dogs indicate larger problems are outside by barking and only deal directly with smaller threats like coyotes on down with respect to size and ability as they are the ones able to get past the fencing. The fence still provides the bulk of the protection. With coyotes on down as bad guys you do not have to have 90+ lb dog. That 90+ lb dog costs a lot money especially if it is valued only for protecting stock and that flock is valued at less than a years worth of dog feed. Smaller dogs and those better suited for warmer climates can do just fine when aided by a fence. My dogs also not confined but they have fencing they can navigate that impedes other dogs and even ground predators. My hunting breed dogs used as poultry guardians are relatively small, smart, fast and have value beyond guarding my flocks which spread out cost between their uses.
Territoriality need not involve behavior towards humans. It does most of time but need not. Not all classic LGD's are people friendly even when they otherwise perform in a stellar fashion with stock animals.
