My intention was to get her some professional training but I am hesitant because I'm not sure I want to keep her. She is very intelligent. We have been doing some basic obedience training. She loves to fetch and retrieves just about anything thrown.

Regarding the space she has to run around, she can go more than 100 yards in any direction. She zips around like a greyhound on amphetamines. How much more space could she need?
