It’s all about training and
patience.
When your dog is about to pee or shit at the wrong
place, bring it to the place where you want it to do the business,
and praise her for doing a good job. If your dog already did it at
the wrong place, dab the pee with tissue and dab it on the
newspaper where you want it to do the business at, so your dog will
know that that’s the place where it can do it.
Then wipe the place where your dog pee or shit with
vinegar to cover the smell.
