How do u paper train a puppy?
If there is a particular place where you want him to go, then put the paper there and everytime your puppy acts as though he’s going to go or starts to go put him on the paper and reward him as soon as he has done anything on it. Eventually the puppy will realise that that is where he needs to go, when he can go out move paper to the exit where you will be letting him out of so when he goes to the paper you can open the door and put him out again rewarding him as soon as he has done anything. You will then be able to do away with the paper. It takes a while but he will get there.
