I have never really thought about it before but after some resarch:::: Dog meat is considered a delicacy in South Korea, China and Philippines. Dogs are being sold in markets for human consumption. They are kept in filthy animal farms where they are crammed in cages not even able to move. At the markets they are hung by the back of their necks, beaten for up to an hour and then skinned alive at the time of purchase. The reason why they're beaten first is to tenderize the meat which is thought to give men verility. They suffer for hours before finally having their throats slit. Other dogs tremble in fear as they watch their fellow friends being tortured and killed.

Poor dogs!
