1. Contact the council. Your details will remain anonymous. 2. Complain to the dog owner. Not just once. Everytime the dogs bark. Make a nuisance of yourself. Make them as fed up as you are. 3. Canvass your other neighbours. You may find that others feel the same, but are nervous about tackling the problem. Going to see them "mob-handed" might be preferable. 4. Arrange for 10 tons of manure to be dropped outside their house. Won't stop the barking, but it'll cheer you up. And it's good for the roses.
