Haven't had dogs in many years. Read the guide dog training book before I got the last ones. If I remember correctly, dog's bladder is not "mature" enough for training until four months. Up until that time, it's you being smart and timing her (which is sounds like you are doing.)
I was the behaviorist for a big school district many years ago. I ALWAYS carried little training treats with me when we were going for our walk. The dog got a treat paired with a lot of positive attention when they went to the bathroom outside. That was done with any training.
