I would use supplements in addition to the steroids. My dog has autoimmune dry eye, and she is actually doing better on the natural anti inflammatories than she did on the steroids and immune suppressant.
Omega 3's. Fish oil and other omega 3s are a natural anti inflammatory. Double the dose, I use the "double strength" fish oil pills and give 4 daily. 2 at each feeding, most supplements are better used when taken with food.
Post gone! Gah! If an autoimmune disease I would want to see a dermatologist and would go with a notebook in hand to jot notes, and ask them to write things down for you. At a university teaching hospital you would get a really great report summarizing what they found so that's another reason I like going there.
The prednisone is the thing that is stopping your dog's system from attacking itself. Picture a school yard fight and the monitor who comes along and tells the other kids to move along so no one else gets involved in it. Without that monitor, the fight goes on and more and more kids get into it, making it much worse.
You can ask about prednisilone which I believe is easier on the liver.
Agree with what Lin says in that make sure you do not add anything that is an immune booster - basically adding more kids to the fight.
Was it Pemphigus?
If DLE that myamom posted that's not so bad as others...right?
