The tradition of eating dog meat dates back four or five hundred years in China, South Korea and other countries, as it is believed to ward off the heat of the summer months. Held every year, the Yulin Dog Meat Festival results in the slaughter of thousands of dogs, which are then served in some of the restaurants in cities in South China. Images of dogs being beaten and gutted in Yulin marketplaces have ignited outrage around the world, as celebrities and politicians throw their support behind efforts to stop the festival. In China, where dogs are increasingly viewed as companions, not food, animal welfare advocates have raised questions about the sources of the dogs, charging that many are stolen pets.
