Dogs are relatively clean animals, and when they have identified a place to go to the toilet, they will be very regular in facilitating there every time.
The first time you let the dog go to the right place to go to the toilet, you must be patient, pay attention to the signs that you find the dog wants to poop, immediately take it to the place where it should go, and when the dog does it right you should praise and commend it;
If the dog has already defecated in an incorrect place, it should be reprimanded immediately and criticized in a rather sharp voice. Usually 2-3 times can be effective.
But pay attention to one thing, if the dog in the incorrect place has been a period of time, do not reprimand it, so as not to be at a loss, I do not know what to scold it, must be timely to teach it on the spot, the dog will understand what they did wrong.
