DO THEY REALLY EAT DOGS IN CHINA?

I don't know about china but...

my sister lived in a large American city in a "little korea" section and she was warned not to let her cat run free.

Yes

The Chinese peasants used to raise Chow's sometimes hundreds at a time, and fatten them up, in case of times of famine in the old system.

Then eat them.
Don't know if they still do or not.

I believe it because I use to live right above some Vietnamese people and one day my cat went missing never to be seen again. Poor little Falcor, he was so adorable but apparently also too tasty to resist.

FalCor stirfry......

They eat anything that moves.

Yes it's true and they do it here too.

I dont know about China but I have a friend who came over from Vietnam 32 years ago and to this day his family eats dog. He has told me stories of them buying german sheperds and other top breeds, and "processing" them in his fathers garage. Hanging the dog to drain the blood like you would do a deer.

It's a Korean tradition. The Korean ethnic group in China eat it too. That's how it spread from NE China to the rest of the country. According to Traditional Chinese medicine theory dog meat (some other animals too, such as lamb) has a blood-warming effect, which is why people living in cold regions like the dish.

Chinese will eat anything...

Yeah they eat the little weiners in a can lol.

Well the slopes eat cats and dogs here so I would say the same slopes eat them in their homeland.

SLOPES? lOL

I've heard many derogatory terms for Asians but never slopes.

In some areas, yes - it's considered a delicacy. That doesn't apply to the whole of China (it's a very big place, with an ethnic and cultural diversity similar to Europe), but there are parts where dog is quite popular (mostly the north, near Korea, and I think also in the far south around Guangdong).

It could be worse, though. I once went to a place where people eat horses... and rabbits... And even larks. And yet in the same place, they won't eat locusts or jellyfish. Culture is a very weird thing.
