I'm working on this with my D (poodle) I gave up using a lure because it wouldn't work with him. He get's touch and the such so it throw him off on what I wanted. I do use a towards me motion with the treat to signal a stand, but didn't train him using the lure. When I tried it he'd just come forward, then sit again fast.
I had more luck just letting him sit on seeing the treat, then moving my hand towards his stomach, making him stand up and saying 'stand' and treating him. Once he realized what my hand was going to do (at first I had to stand him up manually) he'd stand before I touched him. Then I was able to say 'stand' and if he didn't after a count of five or so, I'd start moving my hand slowly towards him. He put then together and gets it now what the word and towards me motion with my hand means to stand.
'Lo was able to learn by luring as kendal advised. But if it doesn't work for Dylan try the above.
