Mine enjoy an occasional dip, but: their skin and eyes can become irritated, so a good fresh water rinse is needed after. Also, as hubby discovered on one memorable occasion, they occasionally poop in the pool, if the water temp shocks them .... make sure they have pooped recently before taking them in. And, it goes w/o saying, be there with them at all times, in case they tire ... I prefer a small wading pool with just a few inches of tap water, that they can bounce in and out of ... messy but fun.
