What the Merck Veterinary Manual says
The total number of red cells, and thus the oxygen-carrying capacity, remains constant over time in healthy animals. Mature red blood cells have a limited life span; their production and destruction must be carefully balanced, or disease develops.
Production of red blood cells begins with stem cells in the bone marrow and ends with the release of mature red blood cells into the body’s circulation. Within the bone marrow, all blood cells begin from a single cell type called a stem cell. The stem cell divides to form immature forms of red blood cells, white blood cells, or a platelet-producing cell. Those immature cells then divide again, mature even more, and ultimately become red blood cells, white blood cells, or platelets.
It is important to remember that a decrease in the total number of red blood cells in the body (anemia) is a sign of disease, not a specific diagnosis. Anemia may be caused by blood loss, destruction of red blood cells (hemolysis), or decreased production. In severe blood loss anemia, red blood cells are lost, but death usually results from the loss of total blood volume, rather than from the lack of oxygen caused by loss of red blood cells. Hemolysis may be caused by toxins, infections, abnormalities present at birth, drugs, or antibodies that attack the red blood cells. In dogs the most common cause of serious hemolysis is an antibody directed against that dog’s own red blood cells (immune-mediated hemolytic anemia).
More from the Merck guidance
Factors that may prevent red blood cell production include bone marrow failure or malignancy, loss of erythropoietin secondary to kidney failure, certain drugs or toxins, longterm debilitating diseases, or antibodies targeted at developing red blood cells. The outlook and treatment depend on the underlying cause of the anemia.
