Ok, what is the story behind these electric collars? I have my 2 year old GSD in a class with a great trainer, but I still seem to be having a problem. My dog is fearful of other dogs. I know part of it is me(I need the training as well LOL) At the last class my trainer recommended a electric collar. I know I am going to get alot of mixed feelings on this, but what the heck. I heard they just bandaid the situation, or else the dog knows when it's on and off. I don't know what to do. Please help.
