jools - I know the problem only too well Keep phoning the council and reporting it to the dog warden. Unfortunately now that you've put a sign there, it often encourages some clowns to see it as a challenge.
If you want something more formal to keep neatly clipped and shaped,the quickest growing evergreen would be laurel, but it does get big and it doesn't look good if you try to keep it small, so it depends how much room you have. If it's a smaller area, privet would be the next best, although it's not strictly evergreen and can lose a bit of foliage over winter. If you want something more informal, you could try Berberis - one of the green ones, as the purples are deciduous. Nice and jaggy too!
