I have had this puppy since she was 7 weeks old, I know the people we got her from, she has never been hurt, or mistreated, but yet when she is excited she squats and pees, or if I get on the floor to play with her she does the same. Any advice out there for this pain in the butt PP pants?

The puppy is still quite young, so she could still not have full control over her bladder, and will grow out of it. If she just does it when she gets too excited, try not to get her excited in the first place, and don't scold her if she does pee. If company comes,don't make a huge fuss over her, and try to be calm if she urinates. She will very likely grow out of this, if it turns into submissive peeing it's a bit more of a problem, but at this age, she just likely has poor control.

It sounds like submissive peeing from what you've described and is something she hopefully grow out of.

Make sure you do not discipline her for doing it or it will get worse
