KayleeGSD, I agree with almost everything you've said in your posts, but I wanted to chime in with two things:
First, you're wasting your time. When people use terms like "Shocking your dog into submission" it is clear to me that they either did not read my post, or can't read for comprehension, because I have never said anything close to that. Believe me, Ninja has not been shocked into submission. He is still the happy GSD he's always been who wakes me every morning by licking me in the face, and follows me around all day hoping for a chance to play. The only time he looks even a little bit like a scared submissive dog is when I call him for a bath -- but that's a different scenario (and no, I don't shock him when he doesn't come for his bath...)
Listen, people are going to believe what they want to believe, so my advice would be raise the dog the best you can and ignore the people on here that have minds like funnels.
Secondly, this isn't quite true:
What I like about the e collar is the fact that it is hands free operation during training unlike using a leash and collar. It is operated using a remote.
The way I do it, it is not hands free. I still use the leash, but I have one hand on the leash and one hand on the e-collar control dangling around my neck. So, in that respect, it isn't easier. It has other advantages, which I outlined in my first post. But it isn't a hands free solution. If you wanted to use it to teach recall, of course, that would be different. But stopping unacceptable aggressive behavior, and training him not to chase cars -- these are all things that I do while he is on a leash AND on the e-Collar. FWIW.
I'm no expert. I just read everything I could, and took the basic behavior techniques used to shape a dog's behavior, and put the e-collar into the mix.
I thought of doing a quick YouTUBE video showing it in action, but the "problem" is that Ninja is such a perfect gentleman when we are out for rides and walks that I haven't nicked him in days.
