If a bear got your buddy the media would have a field day with it, so they are avoiding that buy having these rules, I know for sure you can't leave your pet outside at the camper even if you just walked to the bathroom or took stuff to the dumpster, and as you mite guess always on a teather.
we camped at Cades Cove last year and the camper next to us had a small jack russell that barked non-stop, a little hard to take but we couldn't hear it much over the screaming of MA and PA Kettle telling it to shut up, it seemed like they never talked to each other unless they were on opposite sides of the camper.
it kinda made for entertainment while we were cooking, and the looks that other campers were giving them was hilarious.
