ok, to set the record straight. the water meter is our meter for our property, to which i have to supply a reading to our water company every month!
i have 2 small kids who have to walk pass this every day before going to nursery, i have to ensure they dont touch or walk over the bloody patch where the dog does it business.
the owner has a tree outside his own house, but goes out of his way to ensure he pee's outside my house! this is on the pavement...not on the side anywhere!!
btw you could try bleaching the area dogs usually only urinate where they know another dog has been, if you can clean the area enough it might just walk past next time
