Thanks for the replies. My pool water is maintained at 3 to 4 ppm Chlorine. I test every other day. And I don't shock or add anything (other than muratic acid to keep PH in range) to the pool.
I did a lot of internet searching on this and it seems about 50/50 for and against. I aways have clean fresh water available for the dogs as well.
Thanks.
