Vulnerability to hypoglyc. would really be dog dependent, not really diet dependent - it could happen on any diet if the dog is prone.
As you stated, many dogs will self-fast on prey model. Since you're still describing an appetite (kind of?), I don't know if I'd be too worried yet.
If, however, poos are weird, she vomits at all, her appetite continues to be low, if her energy is lower overall -- then I'd be worrying and I'd probably take her in, if it were me. So, I guess I'd assess what happens tomorrow, and whether her appetite has really taken a dive and go from there.
If she has tendencies toward hypo -- well then I'd take a whole other route and find whatever it took to avoid it.
Is she drinking okay?
