My wife and I had two dogs run with us for almost 10 miles last week. We went for a 20 mile ride out in the country, and these two little dogs, some kind of basset hound mixture, ran with us. We were just taking it easy about 12 mph and they kept up pretty good. But my wife kept slowing down and herding them out of the road when cars were coming. It was pretty funny watching drivers get frustrated at the dogs taking up the whole road. Very friendly little guys, we just didn't have the heart to try to outrun them, they were having too much fun.
