I remember I watched a documentary many years ago, which showed Chinese "dog farmers" who produced dog meat for human consumption, to be sold in the black market (I believe dog meat is illegal in China). The interesting part was that these farmers followed a specific practice: the dogs were practically tortured to death by being slaughtered in a slow, extremely painful way (they were first brutally beaten, and then slowly slaughtered/skinned alive), and all this was done right in front of the other caged dogs, so that the caged dogs could see the process. The farmers said that the extreme fear and stress induced in the dogs made their meat much tastier, and could achieve a higher price in the market. There was some footage of the process, shown in the documentary, that still haunts me to this day...
