I think if you have worked your dog in agility for 6 years and put the pre-novice Obedience title on another then you must be pretty darn good at understanding your dogs and encouraging them to do their best. Congrats on the Pre-Novice too.
Maybe Ms. Poodle just isn't interested. Not all are. Most of the dogs loved agility when we did it but not all.
Have you noticed there is anything she DOES really like? Maybe a different sport would be more rewarding to her. Chasing balls? Morph it into flyball? Or even some junior hunt tests? After all, poodles were originally used for hunting waterfowl and I do see some trialing. Then once you find what is super rewarding for her use it to work on her recall?
Have you checked her hearing and vision?
