YOU TUBE is a great sources for dog training info. You will have to glean through some not so good info along with the good.
As another poster stated you are making the pup fearful of you from what I read of the op. Most of dog training is really training you to understand the dogs pov and behavior. From there you can modify its' behavior.
If you get an e-collar WATCH THE VIDEO AND READ THE MATERIAL SEVERAL TIMES and take notes. Shock yourself with the collar to get an idea of what the dog will receive when you use it. The one I use does not hurt but it is unpleasant. Most dogs will respond to the sound and/or vibration setting with out having to be shocked. Good luck
