I got my GSD at 11 weeks. One of the first things I did was put him on a leash whenever he was in the house. It let him know how things work, and that I was the one in charge of him. It will help establish structure with him. When you take him outside, perhaps put him on a longer line so he has more freedom to explore and encourage him to go to the bathroom outside. When he’s not leashed in the house, I’d recommend crating him. It’s easy to get overwhelmed with all the information out there.
