First off, I don't dislike dogs :).
But I do dislike my ndn's dogs! They have three or four (not sure if one visits) and one in particular is a little bugger. Sustained barking at any little noise from my side of the fence, even the sound of watering the plants. It has dug through and got into my garden twice, and can't be caught without the owner chasing it round. I've got some plastic anti dig board at the small gap along the bottom of the fence, but it just digs under it. The two original escape holes have been blocked off by the NDP, but there's another two holes being dug which I've mentioned, and despite saying they'll block them off, they've done nothing. At the moment I've got large plastic toy boxes covering what I can on my side, but the damn dog just digs further along, and has already dug away a huge part of my flower bed.
Is there anything I can put down which will deter the dog from digging? I tried pepper but it had no effect :). Any barrier gets dug around or under. Ndn isn't interested.
Any good ideas?
