Osage, you must have had some bad experiences involving dogs in campgrounds. Sorry they disrupted things for you.
I haven't ever done a huge amount of camping in campgrounds… usually just a few nights per year… so maybe I've been lucky. I can't recall any incidents in which a dog proved noisy or in which I encountered, er, canine byproducts in an unpleasant way.
Now, noisy generators… that's a different story!
