Very nice. Just a word of caution about letting the munchkins and dog into the excavation. The sides don’t look shored up and it is possible for them to fail. I’m not speaking from experience with pool digs but trench digs. If the pool was excavated from bedrock then the hazard would be minimal but soil is susceptible to failure due to various factors. It’s hard to limit the fun but best to keep them out of the deep end and middle deep to be extra cautious and far from the side walls.
