There is a dance forum here on CC. You will get more informed info there.
You might want to get a copy of Dance Magazine’s college guide.
Her situation is not uncommon at all, in dance, music, theater or art.
She will need to decide if she wants to major in dance (BFA or BA), major in an academic area with dance as a minor or extracurricular, double major or double degree. It is hard to suggest schools otherwise. (Some schools have vigorous extracurricular programs).
How much experience does she have in modern, jazz, contemporary? Does she want a straight ballet program?
She may be surprised: at Juilliard, a top program of course, students get rid of their pointe shoes pretty quickly, we were told. Make sure, if she wants ballet, that that is a focus.
Barnard, Goucher, Vassar come to mind for me. If she wants a conservatory, that is a different matter. With more info I could be of more help.
What are her career goals? I am a fan of doing what you love as an undergrad, but in this case, wondering if she is envisioning a career in dance.
