I cannot imagine a doggie that is housebroken suddenly becoming one that is not housebroken. I've never heard of that in my life.

Is there someone home with her everyday all day long?

Have you lived in the same home since you've had this doggie?

There is only one possible medical issue that I can think of and I don't really know if that could be it since I haven't read up on it lately. That would be possibly some problem with her kidneys, maybe even kidney stones??? Perhaps someone else on here has some knowledge on that topic.
