It depends on the jurisdiction.
Must Dogs Be Kept Leashed?
The Bureau of Land Management (BLM) and the U.S. Forest Service (USFS) do not require dogs be kept on a leash when boondocking on open lands, where dispersed camping is allowed. However, the BLM and USFS does require dogs be kept leashed on developed campgrounds or other improved areas.
The Bureau of Reclamation, which overseas water bodies and fishing areas, doesn’t specifically mention leashing dogs, but reserves the right to impound dogs that are left “unattended”.
The National Park Service and Army Corps of Engineers require dogs be kept leashed.
Note that state laws will apply over federal jurisdictions. Also, if your dog were to injure someone, they could pursue legal remedy from you.
