Bests & Worsts Reviews from Amazon

I had serious doubts about this. I have trained dogs for over 50 years, but my current dog is an incorrigible puller. She only weighs 20 pounds, but I was quite tired of having my arm hurt. I tried treats, various choke collars, the gentle leader, everything. This leash works. Immediately. Marvelous! It is a bit awkward to set it up initially on a squirming dog, but after that peace and pleasant walking.
