Does anybody know of a good dog repellent that will deter them from urinating on the corner of my house. There is no border as such to this corner, the house walls just abut onto a York stone public foot path and a public side alleyway. I’ve tried washing the wall and pavement down with a Jay’s fluid solution. The odour from this deters the dogs for a day or two. I’ve also sprinkled pepper dust around the wall and pavement but this just blows away or washes away with the rain. I think what I need is something that can be sprayed on the wall that will last at least a week even through rain and hail. Apart from the staining and odour caused by the dog urine, I’m sure that the acidity is doing my early nineteenth century brickwork no good at all. Any suggestions welcome
