If you checked past posts about pulling then you probably came across mine and my troubles with Riley. We are now using the Easy Walk harness for our walks and we are doing pretty well. I have not experienced the "miracle cure" that many others have. We are still working on his walking skills. He does pull a lot less, but he will still do it if I give him a chance. It's still work, but it IS getting better.
There is hope for you and Bentley. Sometimes it takes a lot of time, but it is so worth it when you can have a nice walk with your dog. There's really nothing like that feeling. You'll see.
