I had a Schnauzer who went blind and did that. I think he was also developing dementia. He seemed to get turned around in the livingroom and would lift his leg on the furniture. We knew he would never do that unless solmething was wrong and thats when we figured out he was blind. I would take him to the back door so he could get his bearings and remember the layout of the house. Once he realized he was at the back door he was fine. He did really well being blind and ran out on the deck and down the stairs with no problem. Good luck.
