About Colorado Earthdogs Inc.
Founded in May 2023, Colorado Earthdogs Inc. is a dog club dedicated to preserving the working heritage and unique traits of terriers and other traditional vermin-hunting breeds. While many of our activities are tailored to smaller terriers (15 inches and under), we welcome all dogs to join the fun and discover their natural instincts!
We hold our Play Days in Mack, Colorado, right near the Utah border, and our events draw dog lovers from across the region. Whether you’re experienced with working dogs or just curious about what your dog can do, we invite you to be part of our growing community.
Our Play Days and earthdog events typically feature:
Racing / Fast Dawg
Scent Work
Lure Coursing
Tunnel Challenges
Dog Games and Obstacle Courses


At Colorado Earthdogs Inc., our mission goes beyond fun and games. One of our core purposes is supporting dog rescue. We believe every dog deserves a chance at a loving home, and we put that belief into action.
A portion of the funds we raise goes directly toward helping animal shelters in our community. Our rescue support extends to shelters throughout western Colorado.
As a 501(c)(3) nonprofit organization and a registered Colorado nonprofit, your donations help make everything we do possible—from purchasing equipment and securing event venues to covering event expenses and funding dog rescue efforts.
At Colorado Earthdogs Inc., it’s all about having fun, building bonds, and celebrating what makes dogs amazing. Come run with the pack—you’ll be amazed at what your pup can do!
