If your dog was good up to now about not going in the house, you might want to check if something else is wrong with the dog. It might be something as simple as a bladder infection.
I totally agree at 5 years old and never a problem there has to be a factor that set her off. I am assuming no new dogs in the picture? Is she fixed? Has her feeding schedule suddenly changed? Most dogs once house trained remain trained unless some disruption usually caused by a new pup. If that is not the case I would check with your vet. Also a female kept intact and is never bred can develope incontenance and cancer is she fixed or intact and never been bred? I hope you can find a simple answer and no health issues are at stake here Good Luck with your girl!
