I agree with Gilly's recommendation. I would want to know what food you are feeding. Is it a grain free food? You might try the Pro Plan Salmon for sensitive stomachs or one of the Natural Balance grain free foods. But, that is just a guess. You should run this by your Vet.
It's not possible for us to diagnose anything here on the forums. From the symptoms you have given, I would make an appointment at the vet's and let the doctor have a look at her. The two symptoms could be connected or they could be from two separate and distinct things, and the only way to find out is to go to a vet. Please let us know what happens.
