I believe that a dog that should keep an eye on it's owner.
My GSD I rescued from the pound and initially she would ignore me if I let her off the leash. To stop this behaviour we did lots of walks where there were no animal distractions.
To start the game I would run excitedly in the opposite direction, making all sorts of noise and she would hurriedly follow. When she caught up with me she gets lots of praise.
Slowly I reduced the noise and simply hide whenever she is not keeping her eyes on me.
This has produced a dog that is happy to watch me and I get her attention always.
