I am sorry to hear of your pet's problems. Without the proper diagnosis anemia will be very difficult to treat, there are many different kinds of anemia, and theoretically they could all have different treatments. Ideally I would also need more information to be able to give you the best advice.
From what I understand from the information you have given your dog was anemic at the time he was diagnosed with hepatitis. Then, the original anemia, and the chronic active hepatitis resolved when your dog was treated with immunosuppressive drugs: Axathiaprine and
PrednisonePrednisone
Prednisone anhydrous, and a bile acid:
Ursodiol.
But now the anemia is back. Is this
correctCorrect (new formula)? Did your veterinarian give you a tentative diagnosis as to what kind of anemia your dog now has? Is it regenerative or non-regenerative anemia? Does your veterinarian suspect immune mediated
hemolyticHemolytic anemia anemia? Does your veterinarian suspect blood loss or decreased production of red blood cells? Has the hepatitis returned also?
Prednisone alone can be used for immune mediated hemolytic anemia. But it takes a long course of this medication to work, with frequent blood work. Sam-e (S-adenosylmethionine) at 250 to 350 mg per day has shown to be beneficial for liver disease. Milk Thistle is also helpful for liver disease (use a adult human dose). This can be safely given to your dog if the anemia is suspected to be secondary to the hepatitis.
If you could give me some more information I may be able to give you more advice.
