Woah where is this question coming from? I really hope you're just curious and not hungry.
I my potentially disgusting friend am a friend to dogs. I grew up with a dog (a large Norwegian Elkhound named Louis), and our current dog Lilo is living (quite comfortably) with my in-laws here in Thailand. And no, they don't eat dog. In fact they have another dog, Oishi (ironically this means “tasty” in Japanese) and he and Lilo are great friends, traipsing about where and when they want.
Now it is true that some people in Thailand eat dog. And I have a feeling that the dogs know who eats dog because I have story for you.
When we were building our little room in my mother-in-law's house Oishi and Lilo would constantly bark at this cousin that would come by. In fact. Oishi wouldn't let him come in the house and would chase him away. I was later told by Kookkai (my wife) that that guy ate dog.
So the dogs know.
And I have a more stomach-churning story for you. Hold on to your lunch.
A high school friend of mine Tim taught English in northern China for 6 months a number of years ago. He told me they raise dogs for eating there. He also told me of a strange ritual that he had to take part in.
He went to dinner with a group of people to a certain restaurant. After much eating of unidentifiable foods and imbibing of some amounts of beer, a frozen dog head was brought to the table. Tim had to lick this frozen dog head, light it on fire, and throw it out the window. If I remember correctly I believe he did.
Still have your lunch? Makes my stomach turn at the very thought of it. I'd have to whip out some drunken monkey kung fu in a situation like that because unless you have weapons I'm not doing that. But who knows what you might do under the right social and cultural pressures…
Anyhow, to answer your question no, I don't eat dog, I have never eaten dog, and if someone serves me dog I swear here and now I will slap them in the face like a pimp and call them very mean names that no child should ever hear uttered.
Dogs are pets not food.
