I love your pool. The rocks around it are really cool, and the dogs are really a hoot. My FIL was always paranoid about dogs getting in his pool coz he was afraid they'd tear up the liner. Yours is a concrete pool isn't it?
Those rocks are a continuous waterfall but I didn't have it turned on. My husband actually doesn't like the dogs in the pool because of the dog hair but dang, they love it so much! Hard to make them get out. Yes, it's concrete but we used to have an above ground pool with a liner and it was actually a more fun pool. It was much bigger. And when you're sick of it, you can take it down and haul it off. In ground pools aren't all they're cracked up to be.
