It'll take a couple of generations. Starting raising your kids on only Soylent Green type modern foods, and no meats; then, they'll grow up to find real meat disgusting.
(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)
Only animals I'm against eating is hominids like apes, monkeys and humans. And that is only because of pathogens.
