Possible. Up North here, I didn't want to string that much fence. Was able to circuit my property without having to use a Repeater between spools of wire.

My dog learned quick. She'll still bark at folks wandering by, but she stops well short of the barrier no matter how fast she's moving initially...

Can’t swear to this, having never owned one, but I *think* they now have e-fences that actually zap the dog well within the perimeter, a fair distance from the actual fence.

They may have created it for people who have sight hounds and live where they can’t have fences.

Seems to me somebody on the Ibizan forum mentioned it a while back.
