If he is now off cortisone and he does respond favorably to the NB Duck/potato again, then it would seem to be food related to something in the TWO.
It would be the easiest first step.
I think you should get his cortisol levels tested (it's an adrenal hormone).
If he responds that favorably to cortisone, it may very well be fulfilling a deficiency within his own body. It's not just a medication but a hormone that our bodies actually make. Dogs who are cortisol deficient often have immune issues such as allergies and infections. Not only that, but it effects the thyroid hormone conversion in the body. It is possible it was helping him utilize his own thyroid hormone (it is needed to convert T4 into T3 in the body). It's a fine balance as too much cortisone/cortisol are immune suppressive but then again so is too little.
So if his immune system improved while on it you may wish to look into it further to see if he was starting with a cortisol deficit and that it was not just a temporary fix once he recieved the cortisone.
You may not have to do anything though is he responds right away to the NB duck and potato. That would be the easiest I think before looking into other possible factors.You could then add the fish oil and supplements later and one at a time, once all symptoms hopefully clear up. Keep in mind some dogs are allergic to fish, even the gelatin (from cows) outer capsules that some supplements come in.
