Playing G dorian doesn't mean playing G a lot.

The difference between G Dorian and G Aeolian (pure minor) is that G Dorian has an E in it and G Aeolian has Eb
So if you are playing a solo in G minor, and you put in an E, then you're playing the dorian.

Playing the third and sevenths of chords in your solos will sound good by the way.
