Take care about the dog

Classic superstition in western countries: Chinese people eat everything. This statement is as true as saying that Americans only eat hamburgers and pizza.
While the first mentioned superstition might be true in parts (SOME Chinese people eat almost everything), you do not have to be afraid that your friend eats your dog. With high probability, your friend does not even like dog meat. And even if he does… nobody eats the pet of a friend. Right?
