When Bjorn was younger and not house trained he had a habit of going upstairs to my moms room to poop there. So when I heard him going upstairs I knew what he was about to do and would call him back.
So now he knows going upstairs gets my attention. Sometimes he goes up a few steps and stops and waits. Today he stood at the top of the stairs and would open the door to her room. Then just stand there and wait for me.
He has me trained well 😅
