In 2026, the general rule at almost all public and private campgrounds (including KOAs and National Parks) is that you must never leave your dog unattended at your campsite. Dogs left alone often bark at passersby, dig up the site, or become distressed, which can lead to your immediate eviction without a refund. Even if your dog is crated or inside an air-conditioned RV, many 2026 park regulations prohibit leaving them alone due to safety risks from wildlife or sudden temperature spikes. A supportive peer suggestion: if you need to go somewhere that isn't dog-friendly, look for a local "Doggie Daycare" or use a 2026 app like Rover to find a nearby sitter. Some high-end "Glamping" resorts now offer on-site pet-sitting services, but for standard camping, your furry friend should be by your side (and on a 6-foot leash) at all times.
