A better plan is to change her onto something much blander for a short time - just pick two ingredients - for 4 - 6 weeks thats not going to do any harm.
Then if the symptoms are gone you have eliminated the problem. Add the other things back one by one until teh problem reoccurs adn there you have it.
In the wild your dog is v unlikely to come across pure CLO. Its not that good for dogs so id cut that out straight away. FBO has the benefits of CLO but not the downsides, and the best way to feed tht is to feed some oily fish a few times a week.
Yes dogs in the wild would not haev such a wide and varied diet but in feeding a raw diet we are trying to provide teh BEST - so when you have eliminated the cause of the itches, give her the widest most varied diet you can, especially on the fruit and veg mix (mine get apples, celery, broccoli, spinach, sweet potato, carrots, banana, tomatoes, peppers, green beans, lettuce, spring greens and loads more, and garlic and fresh herbs).
A wide range of fruit, veg and herbs will do the world of good, fish is good too and plenty of different meats. Feeding a very narrow range of ingredients is never very healthy.
