What a great pool!!

Re Gracie jumping (or falling in), we had the same problem with my dog Rags when I was a teenager. (He was quite small, around the size of a Jack Russell) and he could ONLY climb out at the steps. So we used to put him in the pool at all different parts of the pool, sometimes after dark etc, and train him by waiting on the steps with treats, so he automatically swam to the steps where he could get out on his own. We really worried about him getting stuck when we werent there, so we spent a lot of time making him "pool safe".
