Tools can be wonderful if used properly however, using a tool for one thing that is opposite to its intended purpose is just ignorance. I have worked with several different harnesses and none are magic fixers so please stop trying to make them that. Walking your dog on a harness give them the mechanical advantage of pulling you harder. The front clip harness only confuse your dog long enough to teach them to turn toward you which you can just shape without a leash to begin with. Simple put, don't buy a harness with the intent of fixing your dogs pulling with it.
