I just drove past my neighbours property, there are three men working there hammering in fence posts and it looks like they are putting in an electric fence!!!

Update, it's NOT an electric fence, they've put wire fencing on some parts of their garden but mostly they've put a four foot high plastic fencing around the boundry because their dogs usually come to us through a hole in the bushes.
So that's alright then, one of their dogs is a rather big alsation that could easily scale a 6 foot wall, the other is a small "digger". I give them a week!
I don't think this was spurred by us, it's probably because one of their dogs got hit by a car when it wandered onto the road last week.
