Partly — dogs are allowed in some of it
Dogs are banned from every hiking trail in Great Smoky Mountains National Park except two: the Gatlinburg Trail (about 4 miles roundtrip) and the Oconaluftee River Trail (about 3 miles roundtrip). That restriction is long-standing — the park has kept dogs out of the backcountry since the 1930s. But the park is not closed to your dog. Leashed pets, on a leash no more than 6 feet, are allowed in frontcountry campgrounds, picnic areas, parking areas and along roadways — so scenic drives like Cades Cove Loop Road and the roadside overlooks are open to you together. Service dogs are permitted anywhere visitors can go; emotional support and therapy animals follow the standard pet rules. One thing to check first: the National Park Service proposed an improvement project on the Oconaluftee River Trail in April 2026 anticipating "a series of partial and full trail closures" over roughly 12 months, so confirm that trail is open at nps.gov/grsm before you drive out for it.
Where dogs ARE allowed
Considerably more than the claim implies. Leashed pets (6 ft max) are allowed in all frontcountry campgrounds, all picnic areas, parking areas, and along roadways — which covers a large share of how most people actually see this park, including scenic drives such as Cades Cove Loop Road and Newfound Gap Road with roadside stops. Plus the two named trails: the Gatlinburg Trail (~4 miles roundtrip, Sugarlands Visitor Center to Gatlinburg) and the Oconaluftee River Trail (~3 miles roundtrip, Oconaluftee Visitor Center to Cherokee). Service dogs are permitted anywhere visitors can go.
