you can buy some spray from the pet shop it helps

Hope the spray works for you Hazel, all we did with our dog was the newspaper near the back door, then when she went to the back door we let her out and she started to do it outside. x x x

Hope it works Hazel, I would put pepper on her do's and then rub her nose in it every time she does it. Also we used to have a whacker for poppy a rolled up iece of newspaper and she would get a tap on the nose everytime she was naughty it really worked she is such a well behaved dog.
