I have invented a dog leash that stops dogs from pulling. I call the leash "No Pull No Bull". It works right away and takes the air out of the dogs ballon. The leash is not designed for you to pull back on it, you want your dog to do all the pulling. I tested it for 4 years before making the leashes available to the public.
I am a certified master dog trainer with 38 years of training experience. I also train trainers for Animal Behavior College, and Petco Corp.
Best of luck please let me know if I can help you in any way. I do travel around the USA helping people solve there dog problems.
Sincerely,
Carlos Diaz
