Dogs fights.

Dog fights make me very sad. More so then cock fights.  At least roosters would willingly fight each other any way.

Don't get me wrong, I know dogs fight normally.  God knows I've pulled my dogs away from other dogs often enough to know.  However, when they fight it is never to the death unless there's some extenuating circumstances.

To train dogs to fight, the dogs are often deliberately starved and subjected to 'corporal punishment'.  These malnourished dogs are then pitted against other malnourished dogs.  The dogs are forced to continue fighting until one is dead.  And yet, if one of these dogs turn on their 'masters', it is the dog who is put down!
