You don't see that shit every day. This is something that has bothered me for a while. Decent article, great photojournalism. Worth checking out. Here's the reason why it's shocking though.
People have a choice to participate in the violence.
The dogs don't. Even though the violence may have been cut short, it still doesn't excuse encouraging the animals to rip the bejesus out of each other for the shot. There's no excuse for it. Snatch had dog fighting and human violence without this type of rubbish going on. Sorry to sound like an animal rights activist, but it was excessive.
