This works fairly well once you figure it out. It is complicated and cumbersome. The problems is if your dog pulls to the side it can slip around and be difficult to get them back under control. Works for a forward pull-not a sniff every blade of grass pull.
DreamWalker is expensive but would be worth it's weight in gold if it worked 100%. I had a personal call from mfg. customer service rep to guide me thru a more correct sizing of the harness to my dog to make it operate to it's fullest capacity.. Customer Service went above & beyond to help. The harness definitely helps since I could not walk my dog at all because she dragged me down the street pulling so hard. Now, she still tries to pull but the strain never reaches my arm because of the harness and she does not look like she's dragging me down the street anymore. However neither do I feel the harness is "working" exactly as the mfg. implies. After each instance of depending upon the harness to stop the dog from pulling, you are supposed to relax the pull of the handle to the harness as a positive reinforcement of good behavior for the dog. My dog never stops trying to pull so the harness is always in full use! With the harness, she is not dragging me but neither can I get the chance to reinforce any improved walking habits since there are none. Somehow, between the dog and my arm, the harness either absorbs the strain of her attempted pulling or curbs the pulling so we actually can walk without making a spectacle of ourselves. Maybe the mistake is mine in thinking the harness is a training tool or that the dog will give up trying to pull and be content to walk casually down the street like a normal dog. I was torn between returning the harness or keeping it since it was pricey. I did keep it and will probably wish I had the money for something else. The dog can run in the yard for her exercise.. Maybe it would work better on a slightly less anxious-to-be-there-first dog.
