Awwwww.....! Petra and ?? - they are so precious and beautiful! That's great you made a step for Petra. She definitely needs one with her short little legs! The hotter it gets, the more interested they will be about the water!
We had another member, Sunbaby, build a mini-beach entry to her pool just for her dogs. It was so cute. She had min-pins, and I can't remember what else. We tried a hard plastic kiddie pool to use as a boat for our cats to 'enjoy' in the pool, but they weren't crazy about it! Not at all! Oh well, you never know until you try! Our furry families!!!
Your water looks fantastic! I love the plaster and trim!
