I was thinking it would be cool to make a pond/pool type thing for my dogs. then i came across this, would be awesome to make something like that for them, maybe on a much smaller scale, something for them to lay in the hot summer. wouldnt be able to stop them from drinking it though.

anyone ever though of doing something like this?
