Rescue swimmer afraid of water?

Caspar got a new toy, a splash pool water sprinkler. A ring of fountains. But guess what? Our rescue swimmer, which ought to be his job, doesn't like it. He didn't take any of the treats we put in the middle. And also his ball was ignored.
Perhaps when it is really hot, the air that is, not the water.
