Answer
Amy --

Keep in mind that I am not a vet, so that is still your best way to go.  Anything I say, since I haven't been there or seen your animal could be wrong.  However, with that in mind, there are several things that could be wrong, but my best guess would be that she has developed an ear infection of some sort.  That's why she's having balance problems.  In this case, I would recommend taking your animal to the vet as soon as you can so that you can get that taken care of.  I know this probably isn't what you wanted to hear, but it's what is most likely wrong, from the symptoms you've described.  

Hope this is helpful.  If you have any more questions, please feel free to contact me again.  Good luck!
