Erik, My Keoki is 6.5 mos old and we had a similar problem w/him. I guess you could say we still have that problem, since he just did it again last week {ARGH!!}.
He has always stood still and peed in one spot outside. But even as a young puppy, if he peed in the house he left a pee trail. No UTI, no other health problems. I have yet to figure it out.
You're lucky he "pees a little". LOL Keoki left trails from one room to the next. We have hard wood floors through much of the area, and it was sometimes hard to see the pee. There'd be one of two of us, standing or crawling around, cocking our heads at different angles trying to see the pee {it gets "lost" in reflections from lights and windows}. Really, quite ridiculous!
Our female never did this.
Good luck.
