Eating predators is supposedly less healthy than plant eating animals for a few reasons. As I understand it, carnivores have a notably higher level of parasites, they share diseases with other carnivores more readily than herbivores, and they’re more lean and the meat is more tough/stringy.

There’s also a realistic level of sustainable effort to farm raise a carnivore vs a herbivore. https://www.britannica.com/science/trophic-level

It is also kind of dishonest to ignore South Korea which does in fact have industrial dog meat farms.
