Here's a unpopular opinion: invading your neighbours being wrong aside, I feel like eating dog meat isn't morally any worse than eating a pigs or cows. (Assuming they're not someone's pet).
I'm vegetarian, and feel it's unhelpful and judgy to get mad at people for eating meat, I just think people give countries where dogs are eaten way too much crap. To the point I even think it's subtly racist to judge other cultures for eating dog meat (again, I think we certainly should judge Russia and North Korea for invading).
Dogs are cute, but heck cows are too, so like don't get riled up about people eating one, if you happy eating the other.
