Chuck and Buck love our in ground pool. They don't get free range of it but theyre in it at least once a day. They have a kiddie pool in their area that they turn their bill up to.
They're still alive and kicking
It does require more upkeep than normal but the tradeoff is worth it. My son is a pool and open water swimmer. He swims in lakes and oceans 7 days a week that has a lot worse than a handful of duck poop. He also swims with Chuck and Buck in our pool every chance he gets. The boys love chasing and diving to get their human.
