Cleaning up dog poop is not in the FA's job description -- literally or figuratively. However, the FA's *are* representatives of AS, and therefore responsible for messes -- figurative and literal -- of their employer allowing pets free reign in the cabin.

It is not acceptable for first class passengers to endure the stench nor to track down the offending human. It's the FA's job to ensure the comfort of first class passengers. A cover-up of the poop is unacceptable. I expect an FA to get down on his or her hands and knees and properly deal with the problem. If no cleaning solution is available, soda water can work in a pinch.
