OK! So I've included a lot of usful info in this one. It just so happens that dorian really doesn't have any void notes. This makes it really easy to imrpovise in a dorian situation, if you know the scale in all positions you really can't go wrong. BUT, playing randomly in a scale doesn't always sound the best so we need to think about arpeggios, phrasing aaaannnndd......LICKS!
Below I've included charts of the one octave dorian scale as well as each chord and arpeggio that I've discussed within the video.
