Don't even consider a chain or prong because those are just bandaids as well, but they cause pain to your dog.
I've always used the "go the other direction" method, but it works the same way as the "tree" method. If the dog pulls in one direction you *immediately* go in the opposite direction. This will be difficult at first and you will find yourself going in all kinds of directions. But it is imperative that you start in a VERY low distraction environment in the very beginning. And slowly add more distractions in. It can take a dog like 6 months to learn loose leash walking, just depends on how stubborn the dog is.
You have to be more stubborn than the dog is or you wont get anywhere with training. I would keep doing the "tree" method and stay consistent with it. The worst thing you can do is let her pull sometimes but not others. It HAS to be everytime she pulls. Just takes patience and effort on your part. Most people don't have the patience so they just use a walking tool, this isn't a bad thing but it doesn't fix the problem and you have a pulling dog if you happen to not have the tool on the dog!
