National park · Dogs allowed in some areas only

Taking a dog into Yellowstone National Park

Barely. Pets are allowed only in developed areas and must stay within 100 feet of roads, parking areas and campgrounds; no trail, boardwalk or thermal area is open to them. Trained service animals that perform tasks directly related to a person's disability are allowed throughout the park and in all park facilities, but must be leashed.

What Yellowstone National Park actually requires

  • Pets are only allowed in developed areas and must stay within 100 feet (30.5 metres) of roads, parking areas and campgrounds.
  • Pets must be physically controlled at all times: in a car, in a crate, or on a leash no longer than six feet.
  • Pets are not allowed on boardwalks, on hiking trails, in the backcountry or in thermal areas.
  • Carrying the dog makes no difference: pets in arms, strollers, backpacks or carriers are barred from those same areas.

Where this comes from

“Pets are only allowed in developed areas and must stay within 100 feet (30.5 meters) of roads, parking areas, and campgrounds.”

Source: National Park Service — Pets in Yellowstone. Published by the agency that runs it, read and recorded on September 7, 2026 (dataset 2026.09). We publish the operator’s own wording rather than a summary of what other sites report, and we do not turn “varies by location” into a yes.

Before you rely on this

Pet rules, fees and limits change without notice, and staff at an individual park can apply them differently from what head office publishes. Treat this page as the question to ask, not the final answer: contact the specific park and confirm before you set out with your dog.

Other national park policies we have read

Each of these was read at its own source. None of them is inferred from Yellowstone National Park.
