I think most have it right....the first "bad dog" thread and people are lining up to respond. I'll just add my own experience. Since I started camping 40 years ago from tents, to trailers to motorhome, we have traveled with dogs. Yes, we are concerned dog owners, I always query my neighbors about our dogs and even though I've never received any negative feedback, to answer the OP's question, we'd make changes to our plans to accommodate our dogs to keep them quiet.
In that same 40 odd year period and in the last few years where we have done much more RV'ing, We have never had an issue with someone else's barking dog. Now that's not to say we haven't heard dogs barking, it just has never risen to the extent to be bothersome to us....obviously, some are not as tolerant and some are just plane looking for anything to complaint about. Before anyone gets uppity, I don't care for a constant barker either but its never happened...sorry if that's hard to believe. Carry on and have safe travels!
