Sorry to hear about all of Jazz's issues. Dermatologic issues can be very frustrating and take a long time to resolve unfortunately. In terms of the steroid shots, if those are not working there are definitely other medications available that can assist with the symptoms. The first two the come to mind are Apoquel, which is a daily medication that is given orally, and the second is Cytopoint, a once monthly injectable biologic. I have had fantastic success, far greater than with steroids, fighting against severely itchy dogs. The itchiness associated with both fleas and food allergy should be addressed with both of these medications. In terms of switching to a different flea medication, I would switch if you feel you have been finding fleas. If not, then I see no reason to change to something else. Nexgard is typically a really good choice, which is part of the reason it is so expensive. As for the dietary changes, these trials can be very long and often require repetition with different proteins. I usually don't start with chicken since it is such a common protein that your dog has likely been exposed to already. I would have chosen something like salmon or venison. You might want to speak with you vet about why he thought to go with chicken as a first line choice. Anyway, I think the above recommendations are a good place to start. If you are not seeing any improvements are want the advise of a specialist, ask your vet for a referral to a dermatologist. Hope this helps!
