Dogs can live fine on a vegetarian diet, and pigs will happily eat meat or predate. They’re both highly social omnivores. Most likely, they get the same kind of food when farmed, too.
The comparison gets more difficult to prove with cows, and a lot more difficult for chickens. But, a pig is almost the same animal ecologically, and people have pet pigs that live in their house just like a dog.
