Even if that was true (ignoring the fact that shock collars don't work on dog breeds with such thick fur and neck folds and the fact that the dog regularly leaves and is not on stream), if you're so angry about it, why aren't you protesting the companies that make shock collars? Or adopting animals from shelters that are overflowing right now because of the depression most of us are in?
Because it's not about the animal or the care it gets for you. It's pushing a narrative.
