It is still all very basic obedience. I do not use any prong/pinch collars, I don’t use e-collars, all I use is a ball and my voice. Once she’s got a command down you can play with your voice and put a little more pressure into it if necessary. Every now and then a pop on the leash is necessary but I barely use a correction at all. It’s simply not that necessary, I have all the time in the world and right now we are working on the formal retrieve, directionals, come, and the send-away. 

For pet-people this may look impressive but trust me, it’s not. There is far more impressive obedience out there. This is absolutely basic stuff.
