I don’t know, farmers always had dogs on the farm but they didn’t eat them and continued to eat the chickens. Chicken is really great and succulent. Hard to resist frying one of them up and sucking the meat off the bone. Absolutely no desire to do that with a dog.
I read about these Hawaiians that would use stones to wall in an area of water but leave gaps big enough to let smaller fish in. They’d create an environment that was safe (appeared so to the fish) and provide food. This would keep most of them reliably inside the wall. Eventually the fish mature and can’t escape due to their size. And now you have ocean fish that are easy to harvest.
Almost no culture routinely eats meat-eating animals. It is very easy to determine, even in ancient times, that it is incredibly easy to get sick from eating meat-eating animals. This is because predators often catch and eat diseased prey, and end up having a lot of parasites and such.
Not to mention the meat of such animals tastes much worse.
