We camp in state, corp, and national parks with electricity and water almost exclusively; they're cheaper and usually prettier than commercial campgrounds/rv parks. I've never noticed any breed restrictions in them, but some corp parks do have a limit on how many dogs one may bring. Very few of these parks allow dogs on the trails or on the beaches. We crate our little dogs and the boxer thankfully is okay loose in the camper. Stuffed Kongs and split antlers to snack on help keep them occupied. We turn the radio on for them to help block out outside noise, and we close all window shades to avoid visual stimulation. We try not to stay gone more than 4 hours at any given time, and so far, so good.
