Have you talked with your vet about medication. There is some good research and results with Prozac or Xanax for anxiety in dogs.    
I used the Xanax for a year following the anxiety cause by her hawk attack. The medication along with patience and loving worked well. Took a out a year, but it was very worth all the effort. I was able to get the liquid Xanax because the dose was so small I could not cut the tablet up small enough. The pharmacy had to order it for me. Was expensive but I would have paid anything to see her anxiety relieved.    
Starting agility was also a good thing. Gave her lots of confidence and something else to put her mind on.
