A 5-year-2-month-old male Papillon presented with exercise intolerance that had begun 1 week ago. Hematological examination indicated severe non-regenerative anemia. Bone marrow aspiration smears revealed erythroid hyperplasia accompanied by apparent erythroid maturation arrest, and phagocytosis of erythroid precursors by macrophages. Based on these results, non-regenerative immune-mediated anemia was diagnosed. The dog was not treated with an immunosuppressive agent, but with splenectomy, as the first-line therapy. The dog achieved a good hematological response, and has been in good condition since then without immunosuppressive therapy.
