I finally had the shed in the back of my yard dismantled and would so love to put a pool of some kind back there. I'm not talking in ground. My yard is not very wide but is very long. Anybody have any suggestions as to what I could put? Obviously a pool that doesn't have a ladder to get into. A baby pool would have to be very big for the two of them. Also what sort of work is involved in doing this i.e. do you need to treat with chemicals, what if they drink the water that has been sitting? Also I have boarding dogs here all the time and I know the Labs that come would so love a pool. So something large and low to the ground.
