Pietruszka is *very* scared. She easily climbed those stairs outside a neighbours' house, but the only stairs she knows and has ever walked, at our house, have different parameters, such as step rise, tread depth, and so on. This is the moment she realized she's not in Kansas anymore.
@szescstopni Lol, poor doggo. When I was younger we had 2 dogs, and they basically never went upstairs because they were scared of the (winding) stairs. :D
We had cats too, and they always visited us upstairs so I wasn't lonely lol.
