Considering how big the Chinese population, they will eat anything they see fit like dogs and other animals. Also, their culture of eating dogs is not new as well. They even have a dog festival, which is the practice of dog eating. But the problem lies here is that they are eating dogs the whole year round, not just during this festival. Sadly, the cruelty is an inherent part of the dog meat trade: there's a traditional belief that the meat tastes better if the animal suffers as it dies, with adrenaline coursing through the body. So its inherent in their tradition that animal cruelty is accepted.
I can see a lot of hatred directed at the Chinese in this thread. I admit that the Chinese are not angels. Some of their culinary practices needs to be either banned or modified. But what about the others? For example, shark fin soup is available in most of the American states. Do you know how painful is the practice of cutting off the fins from the sharks? And the less we talk about Foie gras, that better.
