I have to say I am a little confused. It was not her decision, unfortunately she is young, and still lives with her parents, and ultimately, these decisions are theirs.
I don't think Sheeba will have the same "fate" as Chewy, they are returning her to the pound, and she will find a wonderful forever home, maybe without men or whatever.

when you do consider another dog, maybe an older one who you are sure has no issues, and who can get along with your whole family.
Good luck.
