Hi Barbara,
Yes, I would suggest that you go back to square one and complete a proper elimination diet. Did you conduct your elimination diet using veterinary guidance? Here’s an article that will give you an idea of what your elimination diet should look like: http://communityvet.net/2010/03/diy-elimination-diet-for-the-dog-an-cat/
Elimination diets take a long time, many months, in fact; and require strict discipline. If your diet wasn’t conducted like the one in the article, it’s time to reconsider starting fresh.
You’ve mentioned some other items that your dog cannot have that you didn’t originally mention. Were those ingredients that you unearthed or did they show up on your dog’s allergy test?
Once you’ve identified his allergies, you can safely begin looking for foods. A raw diet, either homemade or commercial is great, but not if it contains any of his allergens. You could consider looking at Rayne customized diets, if you’re unable to find a commercial diet that meets your requirements or are not comfortable making home-prepared meals that contain none of his allergens, and are most importantly, properly balanced.
