I am a Boomer and we grew up with German Shepards. Whether in our yard or while we were walking the dogs, we cleaned up after them. My Dad had a term for it - “honey dumping.” It was the kids’ job to do it, as well as changing the cat’s litter box at home. Although we weren’t fond of doing it, we had no other chores at home besides clearing the table and loading the dishwasher after dinner. There were three kids, so not onerous. Not going to comment on why you have to be told to pick up poop.
