Confused boxers: what does the tennis ball do in the water bowl?

"Nanu? Why is there a round thing in the water bowl?" The cute boxers wonder in the video when they find a tennis ball in their drinking vessel. The dogs try to fish out the object with their mouths, but that's not so easy ...

"Maybe it helps if we scratch our paws along the edge of the bowl?" The boxers ask and push around their water bowl on the floor. However, they quickly realize that this strategy is not very effective. So they try again the method of fetching the ball with their teeth - and finally they succeed. Most of the time it pays off not to give up right away and just try again and again until it works. Smart four-legged friends!
