What kind of story does "Looking for Dogs" tell?

This film is based on a true story. They repaired their broken relationship on a hike along the Appalachian trail, looking for their beloved lost dog.

The degree of completion is quite good. The dog has been lost for less than 20 days, leaving home 180 km. The man walked 12 miles (38.6 kilometers) in the dark, and it took 12 hours to find the dog, and even got ulcerative colitis. I have to admire this perseverance.
