(continued) Electrical Dog Collars!
Dogs have traditionally lived with humans; they have a mutually satisfactory arrangement whereby dogs assist with hunting, protecting and companionship whilst the humans make the dogs' lives longer and more pleasant by sharing food-supplies increased through the help of the dog.
Dogs communicate their needs and moods very clearly...........unmistakeably, actually!!!!........to humans. Humans have the equipment (voice, facial expression) to communicate in return with dogs (or, in other words, to "train" them so they perform wanted actions and behaviours, and don't perform unwanted behaviours and actions).
Why, in that case, do you feel you must/need to forego the existing technology (that is, the relationship and the communication between dog and man) and instead "get an electric collar and a couple of miles of electrified fencing" to make/force (???) the dog to do something which is totally contrary to its nature.........that thing being to sit alone for hours on end on its own in a field/park/garage/garden/kitchen (and then, presumably, apply stronger and stronger doses of epileptic seizure if it continues to manifest signs of loneliness despair and distress).
The longer I live, the more I wonder about the role and status of homo sapiens on this poor suffering planet!
