My dog is never with other dogs. He's probably one of the most loving dogs I've ever seen, but not with other animals

. Nonetheless, the dogs back then ate meat and only meat and lived for a very long time... (Army dogs especially)
actually they didn't live long at all. and they ate whatever they could get, not primarily meat. dogs are omnivores, not carnivores.
they also never traveled, there were no imports/exports, people didn't travel, and most illnesses went undetected and untreated.
very much the same as it is with humans and vaccinations/medications
