I believe that this should be a regular case by case training thing, not something that lasts for several minutes at a time. It's more a question of ongoing manners training as opposed to reinforcing a sit or down which is less of a natural behavior and needs to be reinforced by repetition. You're also dealing with resource training which is a different thing altogether.

Your trainer will give you good ideas. I wouldn't worry. It may be that you are trying too hard to desensitize her completely too early.
