...And she's 2 years old. I read something about ear taping, but it says you have to do it with a young puppy. Am I still able to tape her ears, or are they doomed to stay halfway there forever?
You could try taping them, but at 2 years it's very unlikely they will ever stand. The taping needs to be done when they are young so the cartilage in the ear doesn't form a permanent crease.
