I agree with that, although I still use a prong to help train Harley to walk nicely. When people area approaching, her inclination is to meet them, which acauses her to pull, which tightenes the collar, and her ears go back. She may not look "nice", but is obviously under my control. I wish I had a better idea as to how to make her see me as the "pack leader", and therefor stay behind me. She sees me as her leader in other areas, so why not on her walks?
