I've been looking into this myself for the perimeter of the garden to keep the dogs in.  Rather than having the expense of fencing right round, i'd only need to do a top wire along the low wall.


Not sure if this would be relevant in your location as I don't know if you have neighbours.  The only problem i've found is that hotwire fences are generally only acceptable in a rural situation but not if you've got the hotwire on the outside of your property with other houses nearby, even with a warning sign.  I haven't found laws about it yet so i'm not sure if it's just a guideline???
