Robertn, I'm sorry to have put so much of my problem into your post. I hope it can help you in some way.
I spoke with the vet again last night and found out more information about the course of treatment-similar to your plan-and more things that were high on the sensitivity list including some foods. He's been on grain free, duck, fish or venison, and potato for more than a year now.
I still can't seem to get over human dander.
The serum must be individually prepared to include the what's causing the problem. I'm not sure if that would be called the "allergen."
Please keep me in mind whenever you find out more.
Thank you.
