Dog-friendly trails and public land rules
Where dogs are allowed on US public land, what the leash rules actually say, and what each kind of terrain asks of a dog: water, heat and what the ground does to paws.
Who manages the land decides the rules
The same dog is welcome on one trail and banned from the next one over. It depends entirely on the agency:
US National Forests
The most welcoming public land for a dog. Dogs are allowed on almost all backcountry trails unless a sign says otherwise, usually to protect a watershed.
US National Parks
Tightly restricted under 36 CFR 2.15 to protect wildlife. Dogs are banned from nearly every unpaved backcountry trail.
Bureau of Land Management
Over 245 million acres across the American West, and the most freedom you will find for backcountry walking with a dog.
State Parks and Wilderness
Designated Wilderness under the 1964 Wilderness Act, and state conservation parks, protecting fragile alpine ground and native plants.
What matters on a trail, for a dog
Four things decide whether a route suits a dog, and none of them is the distance.
Ground heat and shade
Sun on exposed granite or dark rock can burn a paw pad in under a minute once the ground is above 125F (52C). Air temperature will not tell you this. Put the back of your hand on the rock.
Water you can rely on
There is a large difference between a fast perennial stream, a wash that is dry by July, and a still pond carrying blue-green algae, which can kill a dog that drinks it.
Scrambles and drops
Vertical rock steps, class 2 and 3 scrambles, and narrow exposure. A dog cannot place four paws the way you place two hands and two feet, and will need a harness with a handle.
Room to pass
Sightlines, blind switchbacks, and whether there is anywhere to step aside for a horse, a loose dog, or someone who would rather not meet yours.
Regions, and what they ask of a dog
Compiled from agency information and published sources, not from personal visits. Rules and conditions change, so confirm with the managing agency before you travel.
Alpine Lakes Wilderness
Washington, USAGranite ridges, tarns fed by snowmelt, and subalpine forest. Good from early summer into autumn, with water almost everywhere.
Trail tip: snow bridges last into July. Keep a dog leashed near undercut snowmelt creeks, which run faster than they look.
Green Mountain Forest
Vermont, USAShaded hardwood, soft loam underfoot, and mossy river valleys. One of the better places to walk a dog in high summer.
Trail tip: heavy tick season in spring and summer. Use a preventative and carry a tick hook.
Red Rock and desert BLM
Nevada / Utah, USARed sandstone canyons, dry washes and long views. An autumn to early spring place only, not a summer one.
Trail tip: sandstone works like sandpaper on a hot paw. Carry about 1 litre per hour for the dog, and bring boots.
San Juan Mountains
Colorado, USARugged peaks, wildflower basins and high passes. For a dog that is already fit, not one starting out.
Trail tip: thunderstorms arrive almost daily in July and August. Be below treeline by midday.
Pacific Northwest coast
Oregon, USACoastal rainforest, headland views and open beach. Mild all year.
Trail tip: never let a dog drink seawater. Carry fresh water specifically for the dog.
White Mountain Forest
New Hampshire, USAOld granite, steep technical climbing and cool spruce-fir forest. Physically demanding ground.
Trail tip: boulder scrambles can trap a paw. A harness with a solid top handle is worth having before you need it.
