Wow. I am truly floored by this story.
Those poor dogs had such a tragic fate. They managed to escape from a research facility that seemed to have no other purpose than to torture animals. They fled to the countryside, only to be hunted down for killing sheep.
The situation is really bleak. Snitter and Rowf, being dogs, naturally know that they are meant to be with humans. But they can't fathom why men have turned against them. They find themselves stuck in a desolate landscape, having to kill and steal for every meal while being pursued for reasons they don't understand.
It really is a cruel world for animals. Poor Rowf, and poor Snitter. They deserve so much better than this.
