11 hand pony is destroying all our fences. We’ve got a mix of motorway rail/sheep wire and posts with sheep wire and top wire but he pushes them all over. He’s ruthless and incredibly strong. We’ve got to replace the fence between the small paddock used in the summer to stop him getting fat and the hay field, would a mains electric fence keep him in? He wasn’t bothered about the battery one when I’ve run it across the main fence 😬. Any recommendations? My old Arab is scared of the fences and I could put a twig down and he wouldn’t cross it!!
