My Shetland foal, Tartine, has decided she needs to be on the other side of the electric fence, and has learned how to get underneath it by lifting both strands of ribbon up with her nose and almost 'crawling' under it. She does this even when the fence is on full current and it must hurt her - I got a jolt off it the other day. The first time I saw her on the wrong side I blamed the builders who had been in the field rescuing a plank they wanted from the far side, but then a day later I saw her there again and then I watched her do it. Now she just goes back and forth whenever she wants. Right now, it doesn't matter much because the electric fence is only 6 feet from the barbed wire so she has a strip of extra grazing, but later in the spring when I have to control their intake of fresh grass it could cause problems. Those fences are supposed to control cows - how can a tiny Shetland pony ignore them?
