Melanie:
If the Kangaroo diet was helping, is there any way you could get another novel protein source that your dog has not had (venison, rabbit, etc?) There are some dry and canned varieties on the market that might fit the bill, as well as some pre-made raw diets (many raw food suppliers have exotic proteins–my cats vote for Hare Today’s rabbit chunks.)
One of my dogs had seasonal allergies completely unrelated to food. We did the testing route, and while identifying at least some of his triggers certainly helped it wasn’t a cure all. For awhile we did allergy shots and prednisone. It lasted 4-5 days and he’d be miserable for the rest of the month. As he got a little older, we worked for a few years with a wonderful vet on building a healthy immune system any way we could. We added a few things (mostly in the form of probiotics and other nutritional supplements, as well as medicated baths, etc). More importantly (I feel) is that we subtracted things that we suspected could possibly be linked. We gave him only clean, filtered water. We stopped using fabric softener (that helped tremendously!), and stopped giving annual booster vaccines (he was older, even our allopathic vet agreed with us on this) and stopped using flea prevention on him (as it seemed to be doing no good anyway). We let his immune system rest as much as we could. I can’t say it “fixed” him and I can’t put my finger on the one thing we did that did the most to help, but it seemed that the combination of factors helped him build an immune system that knew what it was doing. He had occasional break-outs, but I’d say he was 85-90% better. Just my personal experiences of course. I wish you luck with your little dog.
