Trail Dog Thru-Hiker Registry

Every year, a handful of extraordinary dogs hike thousands of miles beside their humans — crossing mountains, deserts, and entire continents one pawstep at a time. These dogs aren’t just pets; they’re true trail partners, sharing every climb, storm, and summit along the way.

The Trail Dog Thru-Hiker Registry exists to honor those teams — to document, celebrate, and preserve the stories of the dogs who have completed long-distance trails like the Appalachian Trail, Pacific Crest Trail, Continental Divide Trail, Colorado Trail, and beyond.
