Hi Adrienne, had another follow up as unfortunately while a few of these techniques worked for about a week or so she was smart enough to realize that one of the times that she came into get food that the door was going to close and has really started avoiding doors if I am near them even if there are treats around. In order to not spend two hours outside every time we go out (morning, post-walk, and night) I have had to resort to using a tense leash to keep her from moving back into the yard and letting it slacken when she moves in the direction I go when we're near a door.
While this is somewhat working for the time being she'll basically lie in the open doorway until she gets tired of the tense leash and slowly works her way inside. Of course once inside, she immediately tries to turn around and get back out. This definitely doesn't feel like the best solution, and I have to imagine that this is giving her negative feelings around the doorway despite the fact that I try to give her a unique reward when she comes in (peanut butter, large piece of chicken etc). Recently those unique rewards have even lost interest and she will just immediately go into a room by herself.
Acknowledging that it has not been that long since you gave the original advice, maybe I haven't been patient enough. But with her not seeming to be enjoying indoors anymore than a few weeks ago and wising up to going near a door when I am around it, I again feel likes its hard to find a happy medium between being patient with her getting comfortable inside and hopefully wanting to come in more easily and getting her inside in the near term without reinforcing negative feelings she might already have about coming inside or having to be outside for multiple hours every time she goes out!
