This infuriates me, every time I think about it.
I don't understand how the concept of dogs being "unclean" animals ever came to be. It's just... unfathomable to me. How can anyone believe that an animal-- a whole species-- is not only categorically "unclean", but even deserves to be tortured? They believe that dogs were created by their religion's god, correct? (I assume. I know little about their religious beliefs.) Why do at least some of them believe their god would make something so entirely despicable as to deserve such treatment? It's barbaric-- it's inhuman and inhumane-- it's just downright stupid-- and it fills me with white-hot rage and hatred (sorry, I'm not perfect) for anyone capable of such cruelty.
Again, I don't know about that religion, but as a Christian, I can't believe that God would smile upon the torture of any animal. (And there's a big difference between killing and torturing, to explain why I eat meat, use leather, etc.)
That story... It's enough to turn your stomach.
