No specific recommendations for dispersed camp sites, but regarding dog behavior, one of the things that we have found to help (at the suggestion of a trainer) is giving the dog an assignment. Telling a dog to be quiet doesn't mean much to it. Approaching it, getting it's attention, and commanding it to follow obedience exercises it knows by heart is a distraction, and also helps it focus on something normal, which can help lower its stress. This may require an increase in training frequency to make successful.
