I don’t understand the de facto prohibition against eating dog meat, or why people see it as so bad.

If you eat pig and think eating dog is evil, you are a huge hypocrite. I’d eat dog if I could find it on the menu anywhere. I’d eat cat, too, but seeing how scrawny they are underneath all that fur I doubt there is much meat to be had.

I’d eat any animal that was not treated horribly and that was killed humanely.

Meat is meat and killing is killing; pig, dog, horse, cow. There is really no difference.

If you have a ruff time eating dog meat, you are merely leashed by your social milieu and unable to slip the collar of expectation – so despite your dogged resistance to the idea of canine comestibles and even if you think it is barking mad, if you can put your paws on some dog chow in a country where fingers won’t be wagging at you, why not go ahead and woof some down. It might just be a walk in the gustatory park, and a doggy treat.
