I also have an above-ground pool that is attached to our deck, so we have a walk-in staircase, Lexi stands on the first step and then jumps in (sometimes) She hasn't ripped the liner, but its because she knows where to get out, if she does head for teh side we just say, "Lexi, stairs" and she turns around to go to the stairs!
