I’ve had my 3 month old male gsd for over a month and this method seems to be working well so far. I took him out about twice every hour or a few minutes after he ate or drank. I continued to say “(name) potty” until he did. I praised him. After a couple weeks i started asking him to sit at the door before i opened it. After a couple times of doing this, he started to go to the door himself and sit. Be quick though to get to the door because your pup might get impatient and pee at the door. My pup still has an accident here or there but his potty training is improving by doing this.
