I don't think I've ever been to a campground that didn't say that you couldn't leave your pet unattended. As I usually camp single with my small dog, I do have to leave him when I head to take a shower or to the bathroom. He is completely at home in the camper so he is fine. I've never left the campground without him, except last summer when I was passing a kidney stone and had to head to the emergency room in the middle of the night. When I returned he was still sleeping on the bed and didn't seem to notice I was gone. Acclimate your dogs to their new house and they should be fine. But, I don't recommend ever leaving them behind at the campground and going out for a few hours. If they are noisy, it is not fair to the neighborhood. If this past weekend was your first trip, let us know how it went!
