This Wilhelm Busch work, read by the narrator Helmut Hansen, may be less well-known than Max und Moritz or Struwwelpeter, but popular enough to have been translated into English long ago.
This story is a series of short chapters about two dogs, found by two young boys. They explore and test boundaries, as dogs may tend to do.
In the first chapter, the boys are drawn nude, having come out of the water with the dogs.
