Dexter, a little puppy that we've been (and are still trying to) leash walk has been pulling us ahead trying to keep up with his fast walking, and this product, the easy walk, was recommended to us and this product is great for that. When the dog pulls you, the dog ends up turning himself back toward you instead. The leash works without suffocating him when he pulls unlike the leash, and he is becoming a model walker with an ordinary leash on normal conditions (not the dog park, or when there's other dogs around).
When we first started using, Dexter hated wearing it, but now that it means "we're going on a walk" he knows he has to stand still for us to get it all setup for him. It takes under 20 seconds to get it all hooked up. We've had it for a month and no problems yet.
