My trick works on puppies and it does not take more than 3 tries
1. Just take a swipe of the faeces or urine with newspaper where it did its business (make sure the dog is watching).
2. Hold it's collar and let him smell (obviously it'll squirm away but don't let it do so)
3. Lead it by it's collar with the soiled newspaper in front and dump the newspaper where you want it to be at.
Good luck!
