I've been considering this since you first posted . My pregnancies are many many years ago but I can't think that the Basenjis I had at the time reacted differently to it, but if this coincided I would give it some consideration and of course if she returns too normal after that would more or less clinch it.
If you go down the homeopathic road, I would give her Sepia to help stop the peeing as long as you're absolutely sure there's no infection.
