Thanks Ckuhn003!
As stated by AbsoluteApril, you can use the hook, I like the hook handle, it doesn't matter, just be consistent.
I made sure to shield Behira's head in the video, but usually her body language is such that I know I don't need to. I only do that when she seems a little on edge or hungry as an added precaution. To be clear, she's never even attempted a strike since hook training.
