The Rover walker dropped the dog's leash, he ran into the woods at the Grand Canyon, and was eaten by animals. We found his bloody harness and leash in the woods two days later after we rushed home from our excursion to search for him. This happened on March 18,2019, on only the second dog walk. The walker is obviously not trained properly on holding onto a leash (he was a 9 pound chihuahua). Our hearts are broken and we would never use them again.
