She didn’t like at all that I took her photo. She was laying on the stairs with her owner during the lunch brake.

Most likely, she didn’t like the sound of the shutter of the camera.

The nice thing about stairs is that dogs can’t run or move easily with stairs. They can fly up and down a set of stairs but only if they start from the top of the stairs or from the bottom of the stairs. If they are seating or laying down on a stair, it will take them a while to get in position to move.
