I need some help with Elton marking. I've been at my father's house for vacation. He had mentioned recently that last time Elton was there he went to the bathroom in one of the bedrooms. That is not like him. He tells me when he needs to go outside and between me and my father, he takes several long walks along with having a back yard we spend a lot of time.

I work and I will admit that there has been a time or two, I didn't get home during lunch to walk him so I know he has held it for 6 or 7 hours. Never an issue. As many here know, he was a rescue and is fully potty trained even with saying "last call" so he knows its time to go.

I was gone for 2 hours today to go run some errands. My step mother said Elton marked the same room 2 times today. Once my brothers girlfriend saw when my step mom went downstairs to get sheets, he peed on the pillow. It is clearly marking because he didn't have to go and he knows how to communicate that. He also went on a long walk at 1:00 and I was home before 4:00.

My step mom cleaned it up and left carpet fresh pet stuff on the floor. I don't know what to do or what is causing this behavior? I need to be able to take him places and not worry that this will happen. Any tips, ideas besides closing bedroom doors?
