Not that I like the chemical approach myself, but perhaps "Doggie Prozac" might get her over this rough spot? If the problem is anxiety related, maybe she just needs something temporarily to help her calm down. Worth discussing with your vet. (my niece who is a vet found that was the only way to get one of her cats to quit peeing everywhere because it was anxious about the other cats in the household)
Any experience with rescue remedy? I was wondering if something like that might help to calm her a bit….
I haven't used it for critters. My husband seems to get some good out of it for going to the dentist (like most men, he's a wimp!) But that could be placebo effect. Worth a try, since it really can't hurt.
I've heard of people using homeopathic Ignatia Amara for anxiety and have also heard of people giving it to pets. I have never tried it though so maybe do some internet searches about it. I've tried both dap and rescue remedy (pet) when Ruby originally suffered separation anxiety but I cant honestly say they worked.
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.
