That's the great thing about electric fences... It trains the local animals and they learn to stay clear of it even if it is not on. My fence is battery powered but it is rated for all predators even bears and really packs a wallopThe idiot furry child with the broken pelvis survived but it was 12 weeks of carrying the little block head around as she couldn't walk more than a few steps. Evidently it was what she needed as she runs like the wind today and enjoys digging out voles from the pasture. Her brother's nose was inches from the truck's front wheel. They were both very lucky.
Australian Cattle dog won't go near the front fence. He's the one that took two zaps. Both my husband and myself have tangled with the fence and yep, it makes you invent new swear words. But I can swear to the fact that they work.
At the moment the fence is not charged. Doesn't seem to matter. Dogs still are not going near it.
