Sandy, I sure hope you get good news from the mortgage co!
Judy, I have a marker and he will never stop. Fortunately his fave spots are on the tile. But he does mark in places on the wood floor but it doesn't seem to cause any harm. I go round to the usual spots every couple of days and wipe them up. I watch when walking through the house and I can often see the little drops when they are still wet. We have a doggie door in the sliding glas door so they can go out even when we are not here. I've wondered if he would use an indoor grass potty, or not, or use it and then mark his usual territory
