German Shepherd Training

I've been busy with work the last few weeks, and haven't had much time or energy to do much training. I should have watched some videos earlier, I watched one today and made my walks so much easier! I've thrown most of what I thought out the window, and used one simple thing I saw and the dogs didn't go ape **** when they saw other dogs, and the GSD isn't pulling like a freight train. Amazing what one behavior correction can do!
