Final answer:
The most common anemia in veterinary medicine is anemia associated with parasites, whereas, in humans, iron deficiency anemia is more prevalent.
Step-by-step explanation:
The most common anemia in veterinary medicine is anemia associated with parasites. While iron deficiency anemia is prevalent in humans, especially in children, teens, people with dietary restrictions like vegans or vegetarians, or those with chronic diseases, in veterinary practice, parasitic infections are a more common cause of anemia. These parasitic infections often lead to anemia due to blood loss or destruction of red blood cells.
