Haven't pets, especially dogs, been treated as part of the family for a really long time (thousands of years)? https://en.wikipedia.org/wiki/Cultural_depiction

  I can't remember where I read this now, but I seem to recall that dogs were primarily outside companions until recently; the invention of flea/tick controls helped ease their transition inside. I had an inside dog growing up that got fleas one time. It was definitely a lesson in making sure that sort of thing never happened again.
