About Us Blissful contentment. That's how your dog feels after a great run. We have nine athletic dogs and know that it can be a challenge to keep an energetic dog fit and satisfied. That's why we started Good Dog Outfitters. Good Dog Outfitters promotes harness-based dog sports in the Four Corners region of Colorado, Utah, New Mexico and Arizona. Mark and Sandy Schwartz of Good Dog Outfitters organize harness-based dog sporting events for Colorado Mountain Mushers, and offer training sessions to interested dogs & their owners. Good Dog Outfitters also manufactures, on a limited basis, harnesses, necklines, tuglines and other items for harness-based sports. Custom sizes available. Click for Location
