I live in a place where people eat dogs (Vietnam). Especially in the north of the country there are quite a few dog restaurants. But I think it's fair to say that a majority of Vietnamese people don't like this and there is a movement towards banning the dogmeat trade. I think there were new laws passed about it in the last year actually, although it remains to be seen if they will be enforced.

As for a place where you can eat dogs but not pigs, where is that? Most muslims certainly don't eat dogs, since they are considered dirty under Islam.
