Cheryl Goede from "Controlled Chaos Dog Training" makes herself a target

Following is a video made by Controlled Chaos Dog Training group on Facebook. Cheryl Goede (owner and breeder) of GSDs asked for 15,000 "Liked" on their page during a given time period.  If that amount was reached, Cheryl promised to make herself the "bad guy", suited up for a trained K9 GSD (named Khaos) to attack her, AND, she promised up a video of this event as it happens.  Here is the video.  This is her own GSD, trained by professional K9 trainers, as he attacks her.  It's really cool.





I give her a grade of B, as she was fearful of her own GSD knocking her down.  What grade would you give her?
