Somewhere the importance of dogs in a low intensity production setting has been forgotten. Some parties are bringing expectations into mix that indicate dogs are overwhelmingly a threat. I can think of no animal domestication efforts, excepting those with fishes, that did not involve dogs for either herding or guarding. Now we have parties with what are best described as over priced pets that are directing us away from one of the many values dogs have, namely the farm setting. You do not have to have a Ph D in animal behavior or formal training as a dog trainer to have trustworthy dogs. When did this all become so difficult?
when people use their dogs for working, be it herding or police work or guarding the property, do you think that they did no training? I know many who do all of the above and they put in a LOT of work. Not a couple hours here and there of training, but a full day's work every day with the flock.
In a basic farm setting, again the dogs are just turned out and left to roam the farm. They are with the farmer, working from dawn till dusk. The dogs learned by doing and were never left to figure it out themselves. Also, dogs who DIDN'T earn their keep were gone.
So, it's not that it is more difficult to train the dogs. It's that people today seem to assume that TADA the dog will magically be born knowing all it needs to know. Herding breeds will have the basic instinct, but they still need that instinct to be shaped into something useful. In fact, those natural instincts are the main complaint of owners. Herding = chasing and moving animals. With chickens, that equals dead birds UNLESS you put in the training to shape that instinct into something useful.
