Reposting Jim's email, it was garbled for some people:
While walking to and from our dog park every evening I seemingly inject myself into the path of every wayward dog owner with a pulling dog. For those that seem amenable I show them a method that I will give credit to Margie Cherry for showing us at a Sierra West seminar. She has a cute name for it, Calls it 'Suitcasing your dog.' The basic concept is to get the attachment point of the leash away from the neck and chest area and back towards the loins. This is very different than just wearing a chest harness. The nice thing is that you can use this with a flat collar or slip. The technique is basically using a six foot leash and tying a half hitch knot around the dog at the loins. It is very simple in concept, check your boy scout manuals. The leash comes down the ridge of the back and then at the small of the back or near the area of the penis, you wrap the leash around the belly, come back over the top of the dog and then back under the initial length of leash. The dog will look at it for a moment and then walk nicely for you. It also helps with dogs that like to bite their leashes. (they can't get at it.) We baby sit a lot of dogs and a lot of them don't have the manners God gave a Goldfish but using this method every one becomes a perfect citizen. Our little seven year old niece can now walk her own dog with only two fingers pressure on the leash. Quite a dramatic change from before. The nicest part is that you can employ it when you need extra control and then unwrap them when just walking freely or want to give them a little more room to run, No more diving off into the bushes, don't have to buy a special harness or get fitted, always there when you need it. Give it a try on your butt headed males you will be amazed. Thanks to Margie and Good Luck, Jim LaFrom San Jose, Ca now get out there and work dem workn'dogs
