This lead is really good. I use it together with a belt and it looks stable. My dog generally jogs alongside me so it is a little long for us, but it can be done.
I think this lead is ideal for cycling and jogging. A second carabiner with spirals would be good, as well as a loop directly onto the carabiner. I use the lead with my German Shepherd cross (30kg) and Giant Schnauzer (40kg) and am very satisfied. The dog can pull properly without constantly being jerked.
