Autoimmune Haemolytic Anaemia (AIHA) is a disease that is relatively rare in Basenjis. Anaemia is not a disease in itself, it is rather a symptom of another disease or disorder. Unlike Pyruvate Kinase Deficiency which also causes anaemia AIHA is not hereditary.
In the case of AIHA the body attacks and destroys its own red blood cells. In affected dogs, red blood cells are still produced on a continuous basis by the bone marrow, but once released into the blood stream, they have a shortened life span.
