Causes of nutritional anemia in dogs:

1. Protein deficiency: caused by insufficient protein intake by animals or chronic digestive dysfunction.

2. Trace element deficiency: iron, copper, and cobalt deficiency. Clinically, iron deficiency anemia is common. Iron is an essential component for hemoglobin synthesis; copper deficiency can also lead to reduced hemoglobin synthesis.

3. Vitamin deficiency: Lack of vitamin B1, vitamin B12, vitamin B6, folic acid, niacin, etc. will lead to disorders in the production of red blood cells and hemoglobin synthesis, resulting in nutritional anemia.
