Bridgett -

Unfortunately, I cannot diagnose what your dog's condition as I have not had the chance to give the dog a physical exam.  

Obviously, there is something wrong with your dog.  Perhaps you should seek the help of a another veterinarian if you are unable to find a diagnosis with your present vet.
