This site lists areas to hike with your dog. Most of the listed areas are close to Omaha, Nebraska (USA), but some more distant places are also listed.

Areas are rated based on cleanliness, popularity/crowds, trails, and scenery. I like to hike on trails less travelled. If the trails are crowded, then the area will get a lower rating. Trails popular with mountain bikers will also get a lower rating. Not that I dislike mountain bikers, but we tend to get in each other's way. I also enjoy long, rugged trails. Paved and gravel trails will get lower ratings than woodchip trails. I will generally give woodchip trails lower ratings than dirt trails.
