So scary!
Zoe went on an elevator exactly once. When we took her to the specialist for her TPLO, she had to go for a consult one day, and they scheduled surgery for the next, so she was in the hotel with us for the night. I didn't think to get a ground floor, and with a torn CCL, she couldn't do stairs. The first time was fine, because she had no idea. After the floor moved, she decided to never go in one of those demon rooms again. And I didn't force her, for fear of a nightmare scenario like this. Thus, my 85lb dog had to be carried up and down the stairs for pottying.
