shenandoah national park is one of the most dog-friendly in the national park system. the campgrounds all allow dogs, and dogs are allowed on almost all of the trails including the appalachian trail, if kept on leash (6 feet or shorter). dogs are not allowed on ten trails: fox hollow trail, stony man trail, limberlost trail, post office junction to old rag shelter, old rag ridge trail, old rag saddle trail, dark hollow falls trail, story of the forest trail, bearfence mountain trail, frazier discovery trail. these ten trails fall short of a total of 20 miles of the 500 miles of trails of the shenandoah national park.
