I give up ..acoustic treatment for room with vinyl plank flooring

Ok so I have a small dog that for the life of me cannot stop from pissing on my area rug in my listening room. How would you treat a room and leave the floors bare? the room is 13x13 and has only 5 feet of back wall where I sit in the center the rest is open on each side into another room .. floor to ceiling is 7 feet 6 inches ..treat ceiling above the speakers at first reflection? treat wall behind my seat? 

Thanks Tim
i have a rough layout but have no idea how to post images here
