Ah yes - Tani went through about a year of being a
"submissive peer". Any time anyone reached to pet her, she'd piddle all over the floor and flop on her back. We started asking people not to reach for her, but to just ignore her when they first came in (we did the same) and that helped a lot! She did it more with men than women, and only if they reached down to her. It completly messed up my attempts to pass her off as a "guard" dog, though. I wanted her to have the image of scary even though she's a mush. However, when I had to tell people "she'll be fine if you don't reach out to her", we got our image back. By "people", I mean like the cable guy or whatever. Anyway, she doesn't do it as often anymore. You can google "submissive urination" in dogs for more info. Obviously, rule out medical issues first as has been suggested, though. GOod luck!
