Give her your crate command once and then lure her to the crate with a treat and into the crate with it.. first.. (try this a few times).
Correction method I'd use:
Let her drag her leash and a flat collar is enough, I wouldn't go beyond that given she could be fearful of your poor attitude already
(all jokes aside I'd play to her being fearful first). Less is more with pressure, the more I can accomplish with less the more tools I have if they are ever needed and the dog doesn't develop a tolerance.
Use your verbal correction ie: "no" when she lays down (no emotion in your voice just assertive) after you've told her to get in her crate. The first time I would give her your crate command once more ("no" pause a few second then "go to your crate").
After that point, I would give her a verbal "no" followed quickly with a leash correction if she didn't listen, this is a attention getter at this point.. I want her to look to you for direction.
This is a repetitive process, If she were to walk 3 steps then lay back down my correction level goes up.. not my voice the leash correction.
Make sense?
