I use the "comfy control" harness, which is an "As seen on TV product", but hey I bought it at wal-mart for $10. I use it everywhere for Mikey; Pet stores, neighborhood walks, parks, hikes, etc. It really has helped stopped his awful pulling and it is pretty sturdy. It's made like the puppia harness. I quite like it and it seems pretty escape proof.

Good luck with your search!! I really like the Rope-n-go to, do they sell that at petstores?
