j26dog, this sounds like something that would take some time and patience. I just brought my female Gordon(16yrs.) inside in October after her brother died. They had been outside/doghouse dogs for 14 years. We started off letting her be in her kennel only at first. Slowly she is getting more time to roam and only when we are sure she have been outside to use the restroom. I keep her kennel pads old stuff(quilts/sleeping bag) that can be washed if she has has an accident. We are getting there. That said, I am sure her brother would have peed all over the house by now many times, just because....Good luck to you!
