There should be someone who knows what they're doing in the room to supervise and prevent injuries. If OP doesn't have that experience then he's not in a good position to keep his partners safe, especially if she's a beginner and the dog is large. My opinion is that she knows her limits and OP shouldn't push her to do more before she's ready. That could go really wrong in seconds. And if his dog is frustrated, finish him by hand.
Maybe you can, but if you're suggesting that any woman can just give control to a 100 lb+ dog whose only objective is basically to ram a baseball into you, and then spend a half hour trying to pull it out again, and that without practice and a warm-up that such an experience would be remotely fun or pleasant, you're crazy.
