what causes low red blood cell count in dogs?
86724
The main causes of bone marrow suppression that result in decreased red blood cell production include: any severe, chronic (long-lasting) disease (such as chronic kidney or liver disease, Ehrlichia) very poor nutrition or nutritional imbalances. autoimmune disease.

Red blood cells larger than 100 fL are considered macrocytic. When the cells grow too large, there are fewer of them than there needs to be and they carry less hemoglobin. This means the blood is not as oxygen-rich as it should be. Low blood oxygen can cause a range of symptoms and health problems.
3842
Medical conditions that can cause an increase in red blood cells include: Heart failure, causing low blood oxygen levels. Congenital heart disease (born with it) Polycythemia vera (a blood disorder in which the bone marrow produces too many red blood cells)
35189
Low red blood cell count symptoms (anemia) Symptoms of a low red blood cell count include: Significant fatigue. Difficulty feeling alert, having trouble concentrating. Appetite loss or weight loss.

Low levels of ferritin lead to iron-deficiency anemia. This means you have too few red blood cells. Iron deficiency can come from a poor diet or blood loss. Or your body may have trouble absorbing iron from food.
694337
Anemia can be caused by blood loss, decreased red blood cell production, and increased red blood cell breakdown. Causes of blood loss include trauma and gastrointestinal bleeding. Causes of decreased production include iron deficiency, vitamin B12 deficiency, thalassemia, and a number of neoplasms of the bone marrow.

Leukemia. Leukemia itself can also cause anemia. As leukemia blood cells multiply rapidly, little room is left for normal red blood cells to develop. If your red blood cell counts drop too low, anemia can occur.

Some patients with anemia have low hematocrits, and therefore reduced blood viscosities. Another important factor that influences blood viscosity is temperature. Just like molasses, when blood gets cold, it becomes "thicker" and flows more slowly.

Certain diseases — such as cancer, HIV/AIDS, rheumatoid arthritis, kidney disease, Crohn's disease and other acute or chronic inflammatory diseases — can interfere with the production of red blood cells. Aplastic anemia. This rare, life-threatening anemia occurs when your body doesn't produce enough red blood cells.
732611
Abnormalities in a full blood count Abnormalities of the blood sample may include: red blood cells and haemoglobin – low levels (anaemia) may suggest not enough iron in the diet, blood loss or certain chronic diseases (such as kidney disease).

A low white blood cell count usually is caused by: Viral infections that temporarily disrupt the work of bone marrow. Certain disorders present at birth (congenital) that involve diminished bone marrow function. Cancer or other diseases that damage bone marrow.

Pancytopenia is marked by low counts of all three types of blood cells—red cells, white cells and platelets. This condition can be caused by certain medications and by infections. In some cases, it is caused by a cancer or precancerous condition.
157689
Diseases and conditions that cause your body to produce fewer red blood cells than normal include: Aplastic anemia. Cancer. Certain medications, such as antiretroviral drugs for HIV infection and chemotherapy drugs for cancer and other conditions.

Causes for bleeding here include the following: Bladder infection: A lower urinary tract infection (UTI) is by far the most common cause for a dog peeing blood. It can be caused by skin allergies; the anatomy of the urethra, vulva or prepuce; and hormone-related incontinence in spayed females.
24276
Causes of rectal bleeding in the dog. Dogs can have blood on the stool for a variety of reasons. One of the most common reasons include colitis (inflammation of the colon). Colitis can arise from several things including bacterial overgrowth, parasitism, inflammatory bowl disease, or food allergy.

Anemia (low red blood cell count), whether it occurs acutely from bleeding or gradually for a variety of reasons, can cause fainting because there aren't enough red blood cells to deliver oxygen to the brain.
