Bichon puppies knew before to go to the toilet on the mat and forgot what was going on for a few day

I didn't form a habit at all... You have to teach! It's the same as training him to shake hands, play dead, roll, lie down, sit down, and form a conditioned reflex... Before, it was subconscious, maybe there was a smell there and pulled there, but then I didn't want to go over because I was troublesome or couldn't hold it back or for various reasons... The punishment and reward are necessary, train him, and when she wants to pull, she will go around in circles, or sniff and sniff, or lean on the table and chair in the corner, then you have to pay more attention to be careful, immediately take her to the dog toilet, and then don't give her out, wait for him to pull, let him come out as soon as he finishes pulling, and then say okay, Mota head, give him a delicious reward for him, and then when you don't have time for him to finish, you have to let him punish the station, punish the station in the corner, take him to the toilet to see, Then take him to the place where she pulled, let him smell it, and say loudly, don't pull here again! Be louder, although he can't understand what you say, but he understands the tone, you speak loudly, he knows that you are angry, he is afraid and he doesn't dare, you say softly and touch her head He knows it's right, and then he is happy.

Practice slowly for a week, and you will become a habit.
