It is interesting how different countries have their dogs make different sounds.  An American dog goes Woof, a Czech dog goes Haf, a Dutch dog goes Blaf and a Chinese dog goes Sizzle.
This seems pretty offensive, even if it is just a joke
I find it interesting to know how different dogs would sound in different countries and all I'm trying to say is that, people from Asia eat dog meat.
Even though this is just a joke, it comes across as kind of disrespectful. Just because Asian people have a tendency to eat dogs in some spots does not mean that we should make light of it. Different cultures simply have different ways of doing things, and what may be normal here may be weird to them.
