In "The Silver Sword," what happened to Ludwig the dog? How old the parents were when both got taken away?

Stories very often leave some details to the imagination. We are only told of the horrible storm and of how Ludwig was barking frantically a distance away. Ludwig was running around in circles, half-blinded by the forceful rains and wanting to be rescued by Jan. Jan, for the first time, could not give in to the love and devotion he has always felt for his pets. It was either he helped Ruth to save Edek or he went after Ludwig. He chose the former. So, it is up to you to surmise what may have happened to Lugwig. My guess is, he did not make it through the storm. Then again, maybe he did as the rain had already began to ease and we are told that Ludwig made a sudden bolt inland.

As for the parents, the father was a headmaster so although we are not told his age, we can assume that he is somewhere in his thirties to early forties. Again, you need to rely on your creative imagination. If the parents have three children and the oldest being 13 yr old Ruth, what do you think the ages of their parents might be? Being told everything takes the fun out of the story, don't you think?
