We camp with our 2 dogs, a 3 year old 55 lb Norwegian Elkhound and a 2 year 75 lb old siberian Huskie, both males.
We've travelled extensively with friends who were partial to dobes.
Many parks have the dobes on the banned list.
None ban the huskie, and few have ever heard of an elkhound.
If you're calling ahead to make reservations, be upfront about your dogs, even tho that puts you in the position of dealing with thier preconcieved notions.
If you just show up, it's easier. Nobody will turn down a nice dog when he is in their face (licking it)
In the end, it comes down to the dog. Campgrounds are "close places" a lot of people in a small area. My dogs, and my friends Dobes, thank goodness, are friendly to a fault. They love all people big and small, and all other dogs. Our Elkhound tends to freeze in place while other people and dogs explore him. The husky is boisterous, and will sometimes jump up or move to fast to please other dogs.
If your dog tends to get aggresive toward, or bark at, strange dogs and people, then... well I'm sorry, he/she just may not be cut out to be a camper.
More training, or lifestyle adjustments may be in order.
