On the Way

Fifty years ago, the first humans to land on the Moon were on their way there. They sat inside a little space craft, all three of them, most of the journey.

I wonder what a dog would have done, if she would have followed the humans on the trip. There was no place to go out to do what you would have to do once in a while. In the future, when dogs will follow human colonists to other celestial bodies, this problem must be taken care of.
