Does the Vet have the dog on any medication?
Is the Dog hospitalized right now?
Is the dog eating and drinking normally?
You are very lucky! The liver is the one organ in the body with proper treatment and care can regenerate itself. There is a Medication called Denamarin which is SamE and Milk Thistle which has been found to work very well in help regenerate the Liver and clear the toxins. Cortical steroids are also used for both the Liver issues as well as the Lupus.
When asking about the quality of life when living with Lupus, I can personally attest that the life span with proper medication, monitoring and care, you dog can life a good life. I have SLE Lupus and have had been diagnosed with it about 15 years ago. Medicine has come a long way from considering it a life ending illness.
Steroids and immunosuppressants, such as Azathioprine or Cyclosporine may be necessary as well as no or very limited time in the sun.
Hopefully your Dog will respond well and you will have a long life with him.
The Liver as I mentioned has the ability to regenerate itself. There are different types of Hepatitis and most are treated with the same medication as you would the Lupus. This article goes over the various types of Hepatitis: http://www.2ndchance.info/hepatitis.htm
As far as the Lupus, I have seen dogs with SLE do very well with the Immunosurpressive therapy. The life span is much better than that of a dog with Cancer. There are new medications on the Horizon that are awaiting FDA approval. I really belive that this can be managed and your dog will do well. Joan
Nobody can say what will happen tomorrow, but my belief is the with what you have told me and the protocols being followed, he should continue to improve. I would speak with your Vet about the Immunosurpressives like Cyclosporin, if needed. We actually use that for dogs with seasonal allergies.
I feel the Vet was correct in saying that it was a gift that he was Cancer free. Remember that you will have to keep him out of the sun as that becomes an enemy, follow the medication protocol and hopefully he will be in remission and enjoy a long life with you and your family.
Happy Holidays and hugs to your boy!
