5 month old puppy, is 8:30pm to 5 am too much sleep?

I have a 5 month old puppy. She is crate trained and has done very well but lately she doesn't like going to bed at the normal time, which is usually 8:30-9 pm. I get her up at 5:30-7:30 am depending on how tired or late we went to bed. Is that too much time for her to sleep? Should I be letting her stay up later?
