I used to walk my dog with the leash around her neck, like how it was shown in the dog whisperer's show. It sometimes made her choke when she tugs on the leash, but it is still not a bad method as long as you can control your dog to keep him/her to your side and listen to your lead. This product is great if your dog tugs and pull a bit, especially if you are not very good at handling your dog yet. I saw a similar product in retail costs about $25 and i paid only about $15 here. The harness is very easy to put on the dog once you figure out how to use it. It is a great purchase for me.
