Damn. That was nasty. Especially since the dog looks pretty much like mine.
But such is life, my dog probably looks like that on the inside too
But that is indeed rather 'shocking', if I wasn't totally desentized by the interwebs.
I personally get more shocked by animal cruelty (this is not animal cruelty, I know) than when people are cruel towards eachother. Animals and children are so 'helpless' and cruelty towards them is just wrong.
I even feel more bad in movies if a dog dies than if a human dies
