I like the harness myself. I like the dog that is dragging me down the path and I use the lead as much as a steering wheel as I do as a restraint. I also pull chain weight as well.

My path is a little over a 1/4 mile with a slight down grade. I bike the dog down the hill at a pretty good clip and then walk him and the bike back. I do this off the collar with the chain on the harness D-rings. He is running with the bike so there is no pressure on the throat.

If he is pulling me I prefer the harness. If he is running along side the bike I use the collar. EWO
