Lewdogg21,
I have re-read your post and Roxy is hunting and retrieving for herself...not you. What you perceive as head strong I would call dominance over you. Does she place her paw on top of your foot as times??? Bet she does!!!
I also think you have used the E-collar improperly on her and doing so needs to STOP. She is fighting back the only way she knows how...being her own dog instead of your dog.
I would place her in "yard" work (back to basics) for two reasons. To give Roxy another chance to learn and for the both of you to work together as a TEAM.
One the yard work has progressed, I would force fetch her and then continue her yard training on force fetch, walking fetch
etc. You may want to send her to a Pro for some of her needed
re-education.
