Meat is rather different. Just about no kid in America would want to eat a dog. And there's nothing significantly different between a dog and a pig, other than our cultural attitudes towards them.
As disgusting as I've been raised to find the idea, I suspect GP's point might hold have a grain of truth to dog meat, too. Some cultures eat dog -- I suspect if I ate dog meat, especially if I didn't know it was dog meat, I'd probably find it an okay meat.
(that said, I don't believe the physiology of domestic dogs really lends itself to "good meat", certainly not as efficient as domestic pigs, so raising dogs as food doesn't really make sense)
I wonder if there is calculations where dogs would fall on axis of chicken, pork and beef. Probably around pork, but which side and what sort of diets would be allowable.
I think that is just because we haven't served it to them. Serve it a few years and then tell what it is. Could solve that issue. Also I wonder how well decent breed of dog compares to beef, chicken and pork from ecological and economic perspective.
Only animals I'm against eating is hominids like apes, monkeys and humans. And that is only because of pathogens.
