When you reward her, try not being so excited about it. Your excitement is causing there peeing most likely. Try just saying, good boy/girl. And move on. When you come home and when you greet them and they pee, try ignoring the dogs at first when you get home, and just say there names and say hello, but that's about it, dont get all involved in the greet like bending down to their levels and all that sort. This should improve the excitement peeing.Let me know if this works.
