He's getting a running start and vaulting off the top bar of the fence in one certain spot. I'm thinking about putting something spiky on that one section, but am concerned the tard won't see it before putting his weight on it. I can't just get a taller fence, and he's a high energy dog so putting him on a runner isn't a long term solution at all. I could probably spike the fence, then carry him over there and put his paws on it so he knows what's there before he sprints into it... Anyone have any other ideas? Update: I just got back from the store, spent $150 on a solar powered energizer, some conductive tape, insulators, and self-tapping screws. I have to leave the energizer out in the sun for three days before I can turn it on, though. I was going to get a D-cell operated energizer, but that and what I got were the same price.
