Dogs can distinguish things from different places by smell. You can dip the newspaper in his urine first, and then put it in the designated place for him to smell, so that he will remember it. If he makes another mistake, you need to tell him, reprimand him in a harsh tone, then take him to the designated place, pat him on the head (not too hard) and tell him what you mean. You should learn this more often. Or buy a cage and put him in. In fact, the pig in the cage is good for him. If your house is small, take him out to pee regularly every day. You can go out several times a day at first, and the frequency can be gradually reduced. Maybe you can go out three or four times a day and have activities.
If you can't learn the above methods, you can buy an inducer, about 85 to 120, which is available in all pet shops. Spray it to the prescribed place to urinate, and the dog will naturally go.
It is suggested that you should train to urinate and defecate six months ago, otherwise it will be difficult to change.
