What is the difference between D dorian and D minor?

One note: the 6th. D natural minor has Bb, D dorian has B natural. That single note is the whole modal character.

When should I use dorian over a minor 7 chord?

Whenever the chord is not the tonic - a ii chord in a ii–V, or a static minor vamp. Over a true minor tonic, natural minor or harmonic minor usually fits better, because the b6 belongs to the key.

Is D dorian just C major?

Same seven notes, different reference point. Whether you are playing dorian or C major is decided by the chord underneath and by which notes you land on - not by the fingering.

D dorian: using it properly over Dm7

D dorian is D–E–F–G–A–B–C. Those are the notes of C major, played from D. Saying that is accurate and completely useless in practice, because it tells you nothing about what makes dorian sound like dorian.

Why this works

The difference between D dorian and D natural minor is exactly one note. Natural minor has Bb; dorian has B natural - the major 6th. Everything characteristic about the mode comes from that single note. It is what makes dorian sound bright rather than sad, and it is why the mode fits a Dm7 that is functioning as a ii chord: over Dm7 going to G7, the B is the 3rd of the coming dominant, so playing it early makes the change audible before it happens. The trap is the one embedded in the C-major description. If you think of D dorian as "C major from D", your ear will keep hearing C as home and your lines will drift towards resolving on C - at which point you are simply playing C major over a Dm7 and the mode disappears. The way out is to treat B as a target note rather than a passing note. Land on it, hold it, end a phrase on it. Then compare with Bb and the modal difference becomes obvious rather than theoretical.

How to practice this

One note is the exercise. Everything here is about hearing B against Dm7.

Step by step

Loop Dm7 for four bars in frets 5–10 with D dorian selected.
Play only D, F, A and C - the chord tones. This is your neutral baseline.
Add B and land on it on the downbeat of every second bar. That is the dorian sound.
Now play Bb instead of B in the same phrase. The mode becomes natural minor and the whole colour changes.
Add G7 as a second chord and use B over the last beat of the Dm7 bar - you are now leading into the dominant a beat early.
