Ok I have a question for those who have electric netting & dogs. My netting is up but not charged yet. So the dogs of course have their noses up to the netting. I'm afraid when I turn it on they are going to get zapped and then injure themselves horribly. Is the wattage that high? Can you control the wattage of the electric? I haven't looked at the electric charger yet to get the answers yet but was wondering if others have encountered these problems?
