We stayed at a state campground last year and the people in the next site left their little dog in their tent. It barked all day non stop. People across from them said something to them when they returned. Next day they did the same thing. I called the campground. They made the people pack up and leave when they got back.
We have a large dog (Lab). When she goes camping with us she goes with us everywhere. She never barks. She will let us know if someone comes near with a little growl but that's about it.
