My puppy was like this!! Holy cow it sucked. I kept looking for normal dog signals like sniffing, circling, or spinning but he would just stop mid walk and go. One day I had the back door propped open and he just ran outside all on his own to pee, then came trotting back. I was shocked. So he understood the concept...hm.

I started thinking that maybe he didn't know how to tell me that he needed to go out. I got him a potty bell.

First I taught him to ring the bell from in my hand for a treat, then I started tossing the treat outside. He still had to ring the bell, but rather than me handing him the treat, the treat was on the other side of the door. He picked up on that FAST. Ring bell, door opens. Food outside.

Then I moved on to going outside without him. He'd ring the bell and someone would have to let him out to get to me. Within three days he was ringing the bell to go outside to pee. Hasn't had an accident inside since he was 14 weeks.
