The bone marrow responds properly to the decreased red cell mass by increasing RBC production and releasing reticulocytes
Hemorrhage or hemolysis

Diagnosis of Anemia in Animals
A complete history is an important part of the evaluation of an anemic animal.
- duration of clinical signs,
- history of exposure to toxins (eg, rodenticides, heavy metals, toxic plants),
- drug treatments,
- travel history,
- any prior illnesses.
A CBC, including a platelet and a reticulocyte count, will deliver information on the
severity of anemia and degree of bone marrow response
A blood smear should be evaluated for:
- abnormalities in RBC morphology
- RBC parasites.
Anemia can be defined as regenerative or nonregenerative and is based on classic findings noted on a CBC or blood smear evaluation.
