Got 3 of these for my guys.
(Mostly for Darwin really)
I've been Using them for a week and they really are very good.
Darwin is a sniffer, so he's all over the place. Holds back peeing on something then races forward.
So when he hits the limit there is still a jolt (no way of getting away from that)
However when walking normally even at the end of the lead, no pull or strain.
Daughtry is a plodder, out to the end of the lead, head down with the new harness exactly the same except
just slightly loose lead, no pull.
I'm bringing them to camp anyone who wants to try one is more than welcome, just ask
They look and feel flimsy, but they do the job very well.
